Early childhood science in preschool—a conversation on Lab Out Loud

By Peggy Ashbrook

Posted on 2014-02-24

Lab Out Loud logo radio tower broadcasting a signalListen in on a conversation between early childhood educator and researcher Karen Worth and the science teachers hosts of Lab Out Loud, Dale Basler and Brian Bartel, as they delve into the new NSTA Early Childhood Science Education position statement, in Episode 108: Science in Early Childhood Education. This conversation is a mini-course on what children are capable of at ages 3-5 years old, and how to best support their science learning. It is a compelling statement on how intentional science teaching in preschool builds on children’s non-focused exploratory play.
Photo of Karen WorthWorth describes the NSTA Early Childhood Science Education position statement as directed to teachers and educators of all kinds who work with young children, and for parents. She explains that science learning “doesn’t all start in kindergarten, it starts much earlier than that.” I appreciate her support for the professionalism of early childhood educators: “Part of the importance of this is to really push the acknowledgement or awareness that the professionals who work with very young children are very serious professionals who also should be treated as members of National Science Teachers Association and as significant players in the education of our kids.”
Here are a few more of Worth’s statements from the conversation, but don’t deny yourself the pleasure of listening to the entire podcast, perhaps more than once, to gain insight on strengthening your science teaching.
“One of the important overall message here is that in many ways we significantly underestimate the capabilities of very young children to reason in a scientific way, to reason scientifically and to develop ideas about the natural world around them that are based in their experiences in that reasoning.”
“This is a time when they are very curious, very open to making sense of the world around them, so it is a fertile opportunity, or rich ground on which to begin the process of turning that natural curiosity and those abilities into the beginnings of more rigorous scientific inquiry and conceptual understanding.”
EDC Foundations water 2“You first explore a phenomena in a rather open way. The children need to have that exciting, non-directed exploration of the materials and phenomena. As they become familiar, they then move into what one might call little more focused work.” Worth encourages teachers who feel unprepared to teach science to use materials common in early childhood classrooms, and their knowledge that children need to interact with materials,

but to engage children in a more scientific way. She suggests encouraging children to reason because they can think abstractly and do have ideas, about natural phenomena, using their limited experience in a rational way.
Ask, “What is your evidence—what makes you think that?” Teachers can ask questions and focus children’s attention, not through lectures but through guidance. Worth discusses recording results, documentation, as both an instructional strategy and to help children think more deeply about what they are doing.
“One of the things we want to underscore is not to let a formal position statement in any way imply that children’s play is not important – that there is now something separate from the exploratory play and the constructive play that children do. Play is fundamental, that’s the way children learn. We just want to put materials and adult engagement in there, so that that play can become more purposeful. And in the teachers’ head, intentional in terms of building science understanding.”
See the resources that go beyond the “science activity book format” on the Lab Out Loud website to find out how to provide a series of activities that build conceptual understanding. Share this conversation with your colleagues and the parents of your children! Listening to it and discussing after will make great professional development at a teachers’ meeting or pre-service class.
Lab Out Loud is a podcast, supported by the National Science Teachers Association and hosted by two science teachers, that discusses science news and science education by interviewing leading scientists, researchers, science writers and other important figures in the field. You can listen online at http://laboutloud.com/2014/02/episode-108-science-in-early-childhood-education/#play or download the mp3 directly, or find Lab Out Loud on iTunes.
Co-host Dale Basler was a teacher of science for the Appleton Area School District from 1998 to 2012 where he primarily taught physics and physical science. In the fall of 2012, Dale stepped away from teaching science to take on a new position as Technology Curriculum Integration Specialist for a portion of the Appleton Area School District’s K-8 schools.
Co-host Brian Bartel taught biology and chemistry at Appleton West High School from 1999-2013. In 2013, Brian left the classroom to pursue a new position as Technology Curriculum Integration Specialist for a portion of the Appleton Area School District’s K-8 schools.
Karen Worth was on the committee that wrote the position statement and serves as faculty member and chair of the Elementary Education Department at Wheelock College where she teaches courses in elementary education and science education to pre-service and in-service teachers. For many years she directed National Science Foundation early childhood science grants at Education Development Center, Inc. Her book, Worms Shadows and Whirlpools, is my go-to-guide for understanding and implementing science teaching in early childhood.

Science of the Winter Olympics: Movement & Robotics

By Judy Elgin Jensen

Posted on 2014-02-21

Did you see an Olympic performance (perhaps Davis & White’s gold-medal ice dance) that looked so perfect, so flawless, that it seemed almost robotic? If so, you’ll want to watch Olympic Movement & Robotic Design—another installment in the Science and Engineering of the 2014 Winter Olympic Games from NBC Learn and NSF. It’s amazing the parallels between the programming of robots and that of our own organic computer—the brain.
Then take a look at the companion NSTA-developed lesson plans, which are reviewed by several educators before making it to this post. One of the reviewers kept mentioning a variation of have kids sketch this idea, process, or structure—whatever was appropriate. Seems natural for primary students, but middle grades? A quick search on sketches and comprehension turned up these two articles on the value of sketches to student understanding.

If sketching seems a bit foreign, start with the lesson plans for this video, which prompt students to flowchart their programming instructions. This more structured drawing might pave the way for freehand sketches of both macro- and micro-scale ideas.
If you’re tuning in late to this series, look for them at www.NBCLearn.com and www.science360.gov. The downloadable lesson plans in editable Word format are linked below. Remember, if you made significant changes to a lesson, we’d love to see what you did differently, as well as why you made the changes. Leave a comment, and we’ll get in touch with you with submission information.

Olympic Movement & Robotic Design discusses precision and the practice needed to achieve it in Olympic athletics and how a type of robotic flyer called a quadrocopter can mimic Olympic athletic tasks.

NSTA conference tips

By Mary Bigelow

Posted on 2014-02-18

Are you attending the NSTA conference in Boston this spring? At this point, you should be registering, making arrangements for lodging and transportation, and thinking about your lesson plans for the substitute (if you haven’t done so already).

Conference Checklist: PackingIf this is the first time you’ve attended the national conference, it can be overwhelming at first. Here are some suggestions to consider before you go, updated from last year:

  • Consider attending the first–timers session on the first day. This year, Karen Ostlund is hosting the session Is This Your First NSTA Conference? on Thursday, April 11, 8:00–9:00 AM in the Westin Boston Waterfront, Harbor Ballroom I/II. It’s worth the time.
  • Add the NSTA Conference page to your bookmarks or favorites. Be sure to check out the Conference Newcomer’s page.
  • Decide what you’d like to focus on at the conference: More on the Next Generation Science Standards? What content, practices, or crosscutting concepts do you want to know more about? What topics do your students struggle with? Are you looking for new digital resources, textbooks, or equipment? Get suggestions from your colleagues, too. Ask your students what you should learn more about (related to science, of course!).
  • Then go to the conference website and use the Session Browser/Scheduler to look at the session descriptions. You can print out a personal schedule or add the session information to your smartphone calendar (mine is getting full already). Pick a few sessions for each timeslot, in case the rooms are full. There are several conference venues (the conference center and several hotels), so allow travel time between sessions.
  • Download the NSTA conference app to your smartphone or tablet. Search sessions to build a schedule that integrates with your calendar; access maps of the convention center, hotels, and exhibit hall, share the play–by–play with social media, complete session evaluations, and more.
  • Preview the Conference Transcript section on the conference site to access online session evaluations and tools to track your professional development.  This is a great way to show your administrators which sessions you attended—my principal was always impressed that I was at sessions all day into the late afternoon and on Saturday and Sunday!Some hints on what to take:
  • An empty bag—preferably one with wheels—if you know you can’t resist picking up any brochures, handouts, and session materials you encounter (resistance can be futile), although many presenters are now posting their handouts online.
  • Address labels are handy for sign–up sheets and marking your program and other materials.
  • If you don’t have any business cards, get some or make your own. Be sure to include your e–mail address and what and where you teach. These are great to hand out when you’re networking with other teachers, presenters, and exhibitors.
  • A camera is handy to take pictures of equipment, displays, speakers, and new friends.
  • Have an envelope or other system for keeping receipts and other documents. Expenses not reimbursed by your school might be tax–deductible (check with your accountant).
  • Chargers and adapters for your electronic devices.
  • Above all, take comfortable walking shoes and be prepared for the Boston weather!

 

Conference_Checklist-WhileThere_finalAt the Conference:

  • Pick up your badge holder, your copy of the program (there’s one for each day, unless you opt for the electronic version) and other conference materials ahead of time, if possible. Take some time to finalize your daily schedules. I like to put a small reminder in my badge holder with the session names, times, and locations. You can also stash a few of your business cards in your badge holder, making it easier to hand them out to new contacts. Keep your smartphone handy if you’ve created a calendar on it.
  • Evaluate your sessions online. They’ll be automatically added to your transcript.
  • Unless you’ve signed up (and paid for) a special event, the sessions are first–come, first–served. So get to the sessions early. Sometimes the smaller rooms fill up quickly. Have a back–up session in mind in case the room is full.
  • Divide and conquer if you’re attending with friends or colleagues. You can only be at one place at a time, so coordinate with other teachers on what to attend and how to share notes and materials from sessions.
  • Consider taking some snacks and a water bottle (the concessions are often crowded at lunch time). There is no formal lunch break at the conference. Take your lunch to a session if it’s one you don’t want to miss! The presenter won’t mind.
  • It’s tempting to collect every brochure, poster, and promotional giveaway in the exhibit area. It’s like a science wonderland! But whatever you collect, you’ll have to get home somehow. I know teachers who take an empty bag (see above under things to take) they can check on the way home (or you can ship things home via a delivery service).
  • Stop by the booths at registration staffed by local teachers who can fill you in on the many science education and cultural opportunities in Boston. If you’re new to Boston, explore some of the important historical sites.
  • Keep a log or journal of the sessions you attended, people you met, and new ideas. Update your homepage, Facebook, tweets, or class Wiki/blog with a summary of what you are learning at the conference. I’ve even seen teachers Skyping back to their students!
  • Update your conference transcript.
  • Put your cell phone on mute during sessions.
  • Introduce yourself to teachers at the sessions or events. You’ll meet lots of interesting people and make many new personal connections. Although it’s important to keep up with your colleagues and classes back home via texts/tweets/email, take the opportunity to actually talk to the teachers in line with you or sitting next to you at a session. The value of a face–to–face conference is meeting and interacting with real people, and teachers are the most interesting people of all.
  • Attend a session or two on a topic you know nothing about. It’s a good way to learn something new.

Back Home:

  • Share your experiences with your students. Use some of the promotional items you collected as prizes or gifts.
  • Organize and file your notes and handouts. Share the materials and what you learned with your colleagues.
  • Send a note of appreciation to the administrator who approved your attendance at the conference. Write a brief article for the school or district newsletter, if appropriate.
  • Access your transcript online to add to your professional portfolio.
  • Get ready for next year!

Add a comment with any other suggestions.  See you in Boston!

Science of the Winter Olympics: Physics of Figure Skating

By Judy Elgin Jensen

Posted on 2014-02-17

Many would call the figure skating events the most elegant of all of the winter Olympic sports. The spins. The tosses. The leaps. How on earth do they stay in balance? Find out by watching the latest installment of the Science and Engineering of the 2014 Winter Olympic Games, the video series created by NBC Learn and NSF that delivers a behind-the-scenes look at what the medal-seeking athletes really do.
The Engineering Design component of the Inquiry Guide in the NSTA-developed lesson plans explores the idea of how pairs figure skaters move back-and-forth between two independent systems and one cohesive system. The definition of a system can figure prominently in how engineers develop models. What, exactly, constitutes the system under study? Are aspects of the system really functioning independently, and are simply in the same space at the same time? If so, can the behavior of the independent systems be predicted so that one can predict how the larger, single system works?
This is just one question that illustrates where the processes of science and engineering overlap. Compare and contrast the Science Inquiry and the Engineering Design Inquiry in each of the Inquiry Guides for these videos to get a better understanding of how to talk about and incorporate engineering design processes in your investigations.
Figure skating events continue through February 20. Watch for Gracie Gold to nail her leaps. Then show your students how she uses science to do it. The video series, available cost-free, is on www.NBCLearn.com and www.science360.gov. Link to the downloadable lesson plans below. Let us know what you think—inquiring minds want to know!

Planning and carrying out investigations

By Mary Bigelow

Posted on 2014-02-14

According to the editor, “Although the practice of planning and carrying out investigations has always been a part of good science instruction, the student focus often has been more on carrying out than on planning, with teacher-structured investigations far outnumbering student opportunities to develop their own research questions. Giving students opportunities to design and plan investigations allows them to truly experience the excitement of science and better understand the nature of scientific inquiry.”
But this doesn’t mean that the teacher says “Do an investigation” and wait for the students to come up with something. The featured articles in this issue show how teachers can provide background information and preliminary experiences so that students can “practice” real science.
For example, Pond Power refocuses a traditional activity to incorporate research on how algae could be a renewable alternative to fossil fuels.  After an awareness activity in which students examine the algae species found in pondwater, they go on to investigate how to grow algae in the lab and design and then build photobioreactors. The article has suggestions for assessment and interdisciplinary connections. The extensive list of resources has rubrics and additional suggestions. [SciLinks: Algae]
Elementary and middle school students do activities with light bulbs and circuits. Teaching Electricity and Engineering With LEDs shows how to extend this with investigations using LEDs. I like how the authors describe “tinkering time”—time for students to practice critical thinking and brainstorming and how students can use their knowledge to design electronic devices. [SciLinks: Electric Circuits, Electric Current]

For a field biology class, The Bird Box Survey Project would be an authentic citizen science project. The data collected by the students could be used in a variety of investigations on bird behavior.  If your school is not near a nature center or outdoor facility, you can still conduct ongoing investigations—see the SciStarter site for ideas.
The author of Can You Picture That? shares a 5e lesson on how to design and conduct an investigation to test the validity of popular claims. Given a statement such as “Touching a toad will give you warts” or “Listening to classical music increases SAT scores,” students working in teams design a strategy to test the statement. The twist is that they are not allowed to use words to explain their design—only pictures (think of the game Pictionary). Their focus is on the process, not vocabulary such as constant or independent variable (these can be introduced later). The article includes examples of student work and suggestions for implementation. I could see students really enjoying this!
Two other articles describe projects that could be done as student research. Get Grounded in Groundwater has resources for students to investigate their own local water sources. Although The Missing Piece: Classroom-Based Exercise is addressed to teachers, students could design a study of the effectiveness of exercise in class: what kind, how often, how much? Or it could be an interesting action research project for teachers. [SciLinks: Groundwater, Aerobic and Anaerobic Exercise]

According to the editor, “Although the practice of planning and carrying out investigations has always been a part of good science instruction, the student focus often has been more on carrying out than on planning, with teacher-structured investigations far outnumbering student opportunities to develop their own research questions.

 

Science of the Winter Olympics: Faster & Safer Bobsleds

By Judy Elgin Jensen

Posted on 2014-02-13

Controlled violence. That’s what Steve Langton of the U.S. Bobsled Team calls his sport, in which he’s huddled in a bullet-shaped, finned shell made of carbon fiber and Kevlar hurtling down a curving track at speeds over 70 miles per hour. The team’s bobsled designer, Michael Scully of BMW DesignWorks USA, agrees based on a quote from a Bloomberg.com interview: “Just the brutality and the violence of it was something that really left an impact on me.”
So what’s a bobsled designer to do? In the same interview, Scully said, “As a designer, it’s your responsibility to look at those experiences and try to leverage those into design directions.” Turn your students into bobsled designers by first showing them Building Faster & Safer Bobsleds, from the Science & Engineering of the 2014 Winter Olympic Games video series created by NBC Learn and NSF. Then, use the Engineering Design Inquiry from the NSTA-developed lesson plans to create your own bobsled competition.
This is one of those inquiry investigations where allowing students to “mess around” with the materials you have on hand will fuel their creativity. Of course, if someone asks, your students are “observing the materials’ properties” or something that doesn’t sound quite so chaotic!
Tune in to the Games on NBC TV on February 18–23 to see the bobsled (and the USA Team) in action. Then find the video series, available cost-free, on www.NBCLearn.com and www.science360.gov. Link to the downloadable lesson plans below. Leave a comment to let us know what you think!

DiscoverE brings us Engineers Week

By Peggy Ashbrook

Posted on 2014-02-11

Logo for Engineers WeekNext week is Engineers Week, February 16-22, “a time to:

  • Celebrate how engineers make a difference in our world
  • Increase public dialogue about the need for engineers
  • Bring engineering to life for kids, educators, and parents”

DiscoverE website has  an excellent self-guided tutorial for volunteers and educators, with tips and advice on leading a hands-on engineering experience for children ages, and inspiring photographs of children involved in engineering activities. The advice includes:

  • Do the activity yourself before you introduce it.
  • Identify learning goals.
  • Make modifications if necessary.
  • Think of ways to extend the challenge.
  • Emphasize the value of brainstorming and exploration, rather than right and wrong.
  • Use open-ended questions to guide.

Child blows on a the boat sail made in the activity.The website has a selection of activities in case you don’t yet have an engineering curriculum. Use the “More filters here” tab (a bump on the left side of the horizontal blue line) to search for engineering activities for elementary and early childhood, such as, “Curious George Sailboat,” and adapt any that are above the level of your children.
To borrow from author Laura Numeroff…If you give children an engineering problem to work on, they are going to brainstorm a solution. If you give them materials to try build their designed solution, they are going test it and then re-design their solution…Once you and your students get involved in engineering, you will probably want to use resources to expanding the curriculum. DiscoverE suggests:

Cover of October 2013 issue of Science and Children journalScience and Children, the National Science Teachers Association’s (NSTA) elementary journal, publishes “Engineering Encounters,” a column on engineering. Searching for “engineering” on the Science and Children page brought up 43 articles, including several “Teaching Through Tradebooks” columns. The October 2013 issue focuses on engineering. Use the NSTA resources to develop a curriculum that aligns with the Next Generation Science Standards which have a strong emphasis on engineering design.

It’s February, and many of us are focused on groundhogs, candy, and hoping never to hear the words polar vortex again! Spring is still a few months away, so this is a good time to bundle up and get a fresh look at what your science teaching peers are doing. The National Science Teachers Association (NSTA) produces grade-level journals, written by educators, for educators, and they are targeted to your teaching level. NSTA’s February K-12 journals are live online (with select articles being free for all, and full content being free to all NSTA members). Browse these issues for classroom-tested ideas, activities you can use tomorrow, and commentary from experts in the field.

Giving students opportunities to design and plan investigations allows them to truly experience the excitement of science and better understand the nature of scientific inquiry. Just as basketball players need to practice shooting, passing, dribbling, and defense, so too do our science students need to practice real science by asking questions, designing investigations, analyzing data, and communicating results. Engaging in these practices helps students appreciate the wide range of approaches used in science and engineering to investigate and explain the world.

History and nature of science

By Mary Bigelow

Posted on 2014-02-08

If you think that the “history and nature of science” means students reading biographies of scientists of the past, your thoughts may change after browsing this issue of Science Scope. These articles represent lessons that incorporate the past, present, and future of science.
The History and Nature of Science: Is the Past the Key to Our Future? This question is addressed in a study that compares historical studies to those of today. The focus is on evidence as students examine the concepts of uniformitarianism, catastrophism, and climate change. [SciLinks: Causes of Climate Change]
Science Evolving describes a yearlong exploration of famous life scientists that results in a classroom timeline. The author includes a list of scientists, an example of how to guide students through primary sources, and a photo of the timeline. The activities matched up with the content being studied. [SciLinks: Scientist Biographies]

One misconception students have is that plants absorb food through the roots (I wish that fertilizer and garden ads would stop using the term “plant food”). The author of Historical Plant Studies: Tools for Enhancing Students’ Understanding of Photosynthesis developed a 5e lesson that helps students understand photosynthesis by considering historical studies in botany. The article includes descriptions of these studies and some student-created graphic organizers. [SciLinks: Photosynthesis]
Imagine Darwin’s voyage if present-day technology were available then. Evolutionary Technology: Using Google Earth, Cyber Databases, and Geotagged Photos to Enhance Students’ Scientific Practices and Understanding of Darwin’s Theory of Evolution describes an activity that incorporates Google Earth, cyber databases, and geotagged photos and guides students through defining a problem, locating information, organizing and presenting information, and drawing conclusions. Although we may think of students as digital natives, the authors note that they may have a basic understanding of applications but might not be aware of all of the capabilities. “Teachers may need to create a lesson focused solely on how to use the tool.” But then just watch them! [SciLinks: Charles Darwin, Galapagos Islands, Biological Evolution]
Who would think of using the lowly and annoying housefly to help students understand scientific principles? Don’t Swat That Fly! Using House Flies in an Inquiry Activity embeds the study of adaptations and characteristics of houseflies into a “mystery” to be solved. The article includes a copy of the activity worksheet/directions. [SciLinks: Insects]
Solving a present-day, authentic problem is the focus of Tracking Science: Following the STEM Trend*. After a review of related science concepts, students identified a problem, planned a solution and constructed and tested their trackers. [SciLinks: Seasons, Solar Cells]
The future of science is in our classrooms today, assuming that students choose STEM-related careers. The authors of Career Simulations: Technology Tools That Support STEM Content and Motivation describe several free science simulations that connect science curricula to real-life experiences, such as forensics, neuroscience, and medical research. The URLs of the projects are noted at the end of the article.
Trying to find an alternative to the do-a-report-on-a-career activity? Connecting Students to STEM Careers describes an ongoing STEM career awareness project that ties into curriculum topics. The project consists of 3-5 minute videos and fact sheets on 89 careers (so far). These emphasize technology and engineering, the inclusion of female and minority scientists, opportunities for creativity and problem-solving, and related careers that do not require 4-year or graduate degrees. Talk about going beyond the “mad scientist” stereotype! The authors note that “teachers who do not have a whole day to devote to STEM careers can add video clips to daily or weekly instruction.” I had a day or two in between units for students to catch up on tests and reports. These videos would fit in there.
If you do want to have a career day with guest speakers and other events, Tried and True: How to Organize a STEM Career Day has suggestions for planning, a timeline/checklist, and samples of invitations and schedules. Seeing this gives you an appreciation for what goes into an NSTA conference!
