There are many ways students can be motivated in science. Some students have a passion for the subject that goes beyond the classroom. Others may find the types of activities in the classroom to be motivational—working with others, using technology, or having options for how they demonstrate their understanding. This issue features articles that describe a variety of creative ways for students to communicate their ideas and share their knowledge.
Blending a science unit on motion with art led to an interesting way for students to communicate their understanding of the concepts. Science + Art = Enhanced Learning Experiences for All Students includes several examples of student expression—what a wonderful opportunity for students to express their learning! With the abundance of visuals in science publications, websites, and apps, students can (and should) be producers as well as consumers of these visuals. [SciLinks: Force and Motion]
Physical activity in science lessons can also be motivating for students, such as the projects described in Stomp Rockets: A High-Impact Exploration of Science Concepts*. [SciLinks: Rocket Technology]
Every Assessment Tells a Story describes a classroom-based action research project on alternatives to traditional tests. In a story assessment, students are presented with a narrative and a set of questions or tasks related to it. After trying these assessments along with more traditional ones, the author discovered that scores of assessments with stories were higher than traditional tests on the same concepts. Students indicated that they felt less anxious with the format. Some students even looked forward to them. Two examples are provided, along with guidelines for creating story assessments.
Standardized Test Questions: A Tool for Developing Students’ Proficiency with the Framework’s Science Practices describes strategies and sources for finding test items that assess higher-level thinking and relate to the NGSS. The authors suggest incorporating these items into everyday instruction, such as in exit tickets, writing prompts, and evidence circles. Exploring concepts through virtual environments is the topic of Engage, Elaborate, Evaluate! Virtual Environment-Based Assessments of Science Content and Practices. The authors provide the links to the modules, including the one on weather described in the article. [SciLinks: Weather and Climate]
Many students and teachers are using electronic discussion boards and forums to communicate. If you need some suggestions on how to begin and manage such a discussion, The Leonardo Strategy: Scientific Discourse and Argumentation in an Online Environment* describes the use of a structured format. The teacher poses a stimulus question with an image and students can respond to the question and to other students’ responses. The authors provide examples of stimulus questions and examples of students’ participation. They also share the results of a study on time spent on participation.
Scientific Explanations and Arguments* (this month’s Teacher’s Toolkit column) describes argumentation as “not simply the generation of a final product, it’s an ongoing dialogue through which scientists build new understanding of the natural world.” The authors compare argumentation as a culminating activity with knowledge building; they provide three examples of exploratory argumentation that they used at the beginning of units of instruction on plate tectonics, evolution, and the particulate nature of matter.
Do you have students that are English language learners? The authors of Supporting Linguistically Diverse Students in an Era of Science Education Reform offer six strategies for working with ELL students (or “emergent bilinguals”—what a powerful description) that focus on what these students can do.
Using Place-Based Inquiry to Inspire and Motivate Future Scientists* integrates scientific inquiry with place-based education (in which students learn through direct experience with an environment instead of indirect presentations or textbooks. The lessons described incorporate typical field trip planning with a 5E model to produce a study ecological study of their school grounds. The article includes project ideas, a sample activity sheet, and rubrics. The resources at the end of the article include suggestions for field guides, safety, and tools for exploring the environment.
Exploring concepts through virtual environments is the topic of Engage, Elaborate, Evaluate! Virtual Environment-Based Assessments of Science Content and Practices. The authors provide the links to the modules, including the one on weather described in the article.

This April, the National Science Teachers Association (NSTA) will feature a special strand “Teaching Elementary Science with Confidence!” at our 2014 National Conference on Science Education, in Boston, April 3–6.
With limited time, resources, and opportunities to learn science, elementary teachers sometimes find teaching science within the school day to be challenging. There is a constant struggle to find the time for engaging students in active science experiences. We also know that simply doing a science activity does not produce a deep understanding of concepts. This strand provides opportunities for elementary teachers to enhance their content knowledge, locate resources, incorporate science and engineering practices from the Next Generation Science Standards, and explore classroom management strategies when teaching science.
Sessions organized around this strand include a featured presentation on Friday, April 4 10:30–11:30 AM (“Chrysalis: Transforming Your Teaching”) by Steve Rich (NSTA Director for Professional Development; Director of GYSTC, University of West Georgia: Carrollton, GA). More sessions on Teaching Elementary Science with Confidence include the following:

For all those who are experiencing the solid form of water or teaching about it, here is a cool video from the National Science Foundation (NSF) about the science of ice. In this short video, athletes J.R. Celski, Britanny Bowe, and Gracie Gold talk about the ice they like and mathematician Ken Golden of the University of Utah explains why the unique surface of ice enables the slide and glide of winter sports. The science is several levels above early childhood understanding but it’s good for teachers to stretch ourselves as we prepare to answer at least part of our students’ questions at an age appropriate level.
The NSF has other videos about the science and engineering of the 2014 Olympic Winter Games. Add your favorite resource about water in any form by commenting below.

We are surrounded by data. When you read, watch, or listen to the news, you are presented with the conclusions drawn from data someone else has collected. And they’ve collected that data to understand something, argue a position, make a point, or persuade the listeners to adopt a particular view. It’s important to realize that everyone has an agenda of some sort, and being more data literate helps you understand if others are making a fair argument.
Data literacy is an important skill to develop in students, and science classrooms are a good place to do that because data collection and interpretation are part of the science curriculum in most jurisdictions. What authors Michael Bowen and Anthony Bartley realize is that the “challenge in encouraging teachers to do inquiry investigations exists in part because of aspects of data collection, analysis, synthesis, and presentation that teachers of science often just do not know.”
The authors developed Basic Data Literacy: Helping Your Students (And You!) Make Sense of Data after years of presenting workshops at NSTA conferences on this very subject. This book is designed to help teachers and students make sense of data in ways that are conceptually grounded in hands-on practices and reflect how scientists use and present data.
The examples included relate to classrooms and the types of data collection activities that teachers have students do. As every teacher understands, supporting students who are doing laboratory investigations of the student-directed and open-ended type is a considerable challenge and can require a lot more background knowledge than undergraduate teaching programs often provide.
Learning about how to analyze and make better sense of data also helps you learn the best way to collect data. And learning how to collect, summarize, and analyze data is a very important skill, central to the newly released Next Generation Science Standards (NGSS).

This book is also available as an e-book.

And if you feel inspired, please keep the communication flowing in both directions—we’d love your comments on what you liked, didn’t like, and especially on what works in your classroom!
All students must be provided with equitable opportunities to be captivated by the wonders of science. This month’s issue is filled with resources for making science in your classroom engaging, inclusive, and accessible to all.
Featured articles (please note, only those marked “free” are available to nonmembers with out a fee):
Providing students with a variety of ways to communicate their ideas and share their knowledge helps build their confidence and keeps them engaged. Check out the activities in this issue for creative ways for students to express themselves in the science classroom.
Featured articles (please note, only those marked “free” are available to nonmembers without a fee):
Teaching science has important implications for human society and the future of our planet. All students will need to make ethical decisions about complex socio-scientific issues that arise as a consequence of new science and technology. This issue of The Science Teacher focuses on bioethical issues such as genetic engineering, access to health care, and personal medical decisions. Students will also need to be able to think critically about energy allocation, individual resource consumption, climate change, access to food, and distribution of scarce resources. By emphasizing these socio-scientific connections, we help students learn important content while developing their ability to make informed decisions about critical issues. This edition of the journal will help you bring the necessary emphasis to your own classroom.
Featured articles (please note, only those marked “free” are available to nonmembers without a fee):
Given the financial pressures faced by many colleges and universities, the hiring of temporary faculty has become more common; read about the challenges and benefits of being an adjunct professor in Ann Cutler’s Editorial and in Robert Liftig’s Point of View. Don’t miss the article on an outdoor environmental project designed to connect with students’ real-world experiences in the Two-Year Community column. And don’t forget to read the Research and Teaching article on a new instructional model that focuses on teaching students to use foundational principles rather than rely on a multitude of facts to improve their understanding of core scientific concepts.

As the editor notes: “All students will need to make ethical decisions about complex socio-scientific issues that arise as a consequence of new science and technology.” So how does this translate to the classroom? The featured articles in this month’s issue describe several classroom-implemented lessons and units that go beyond the presentation of content to including the processes of analysis and argumentation—helping students exmine issues and develop their ability to make informed decisions.
Using popular fiction as a context for evaluating the effects of genetic engineering is the focus of Bioethics in the Hunger Games. The authors provide connections between the book and science concepts. They include assessment prompts aligned with Bloom’s Taxonomy and a chart that could be shared with students on determining the credibility of their sources. The culminating activity is round table format for presenting student arguments. There are suggestions for setting up and using a round table presentation (including a rubric). [SciLinks: Genetic Engineering]
Justifying a position on socio-scientific topics through argumentation is also the featured process in Beyond “My Opinion Versus Yours.” The article includes a strategy called the Silent Debate, in which pairs of students support their arguments by writing on a piece of paper that they pass back and forth. I can see how this idea prevents shouting matches and allows all students to participate, not just the more vocal ones. [SciLinks: Bioethics]
This month’s Green Room column has suggestions for going Back to Ecological Basics. The author’s big picture: To function, all organisms and ecosystems rely on a constant cycling of matter. How can human behaviors affect these cycles? [SciLinks: Water Cycle, Carbon Cycle, Nitrogen Cycle, Phosphorous Cycle]
I was intrigued by the subtitle of A New Take on the Field Trip: A low-tech, inquiry-based virtual field experience. The author describes a process she used to create a virtual field experience that could be replicated for any topic and subject area. She provides a step-by-step procedures for planning, constructing, and sharing the experience. Although her examples feature on earth science, the process could be applied to any content area (a trip inside the cell?). The extension is also interesting: Having students use the process to create experiences. This could be an authentic assessment opportunity. In this month’s Connections the author shares a sample virtual field experience and more suggestions. [Use SciLinks to find graphics, maps, simulations on a variety of topics]
Perhaps students could take a virtual trip to explore Micro World. The article describes a study of microfossils and pollen, and I learned a new word—palynology, the study of ancient or modern pollen from 5 to 500 microns. [SciLinks: Foraminifera, Fossil Pollen]
Personalizing Science includes four lessons and five strategies for engaging students in socio-scientific issues. The author includes a matrix showing how the five strategies mesh with lessons on food choices (nutrition), heart transplants (circulatory system), herbal supplements (organic compounds), and Huntington’s Disease (molecular genetics) and were implemented in core science courses.

Working in a school with teachers who have a different expertise than I have means I have access to an informal professional learning community’s broader depth of knowledge. Early childhood teachers represent a wide variety of cultures, ages and educational backgrounds. This variety is a strength when we learn from each other.
Sara Fritel Johnson is an early childhood educator with graduate degrees in early childhood special education and reading. She has worked extensively with public and private school children ages 2 to 8 years old. I asked her how I can best support all children’s learning when I model teaching science activities, such as the one on the movement of 3-D geometric shapes in the January issue of Science and Children, and she agreed to be a guest on this blog in interview form. Welcome Sara!
Peggy: When introducing preschoolers to new vocabulary words such as names for geometric shapes, are there any tips for helping children master the pronunciation and remembering the names?
Sara: Using a multi-sensory approach will help all children. You can use visuals, real materials, whole body movement or smaller movements to help them remember new vocabulary words being taught. I think it is especially important to let them handle the materials – not just watch you as the teacher handling the materials. For example, when you are reading a book, the children can be holding shapes and when you come across “their” shape, they can hold it up or bring it to you.
Peggy: How can we help children who have fine motor difficulty manipulating ramps and rolling objects, or using scissors, participate in these activities?
Sara: When manipulating ramps and rolling objects, some children can be accommodated by using larger balls (e.g. golf ball instead of marble or 4 inch ball instead of golf ball). If they are having difficulty manipulating ramps, you could hold one end while they hold the other. You could also have children describe how they want them placed and then put them in place using hand over hand assistance (your hand over their hand).
When using scissors, if children are having a difficult time snipping paper, you can verbally prompt them “open, close; open, close.” You can also give them hand over hand assistance for this. If they are able to cut, but are having difficulty staying on a line, you can help hold the paper, so they can focus on cutting instead of having to focus on holding and cutting. Eventually, they will be able to use both hands – one for cutting and one to hold the paper.
Peggy: What are some general ways teachers can to check ourselves to ensure we are meeting the diverse needs of all the children in our classrooms?
Sara: Ask yourself – Are all the children participating and are they engaged/having fun? If the answer is “yes,” then their needs are most likely being met. If the answer is “no,” chances are you need to reflect on your lesson and possibly talk to students to see what you can do to support their learning. Sometimes asking students, “How can I help you?” opens up the conversation for them to tell you with what they might be struggling. For example, if you are working on a cutting activity and one student is just sitting there, asking them how you can help will give them the opportunity to say what is difficult for them. If students don’t respond, I usually say, “Let me show you how we can do this,” and then give them hand over hand assistance and give them more independence as they demonstrate more confidence. If the activity is more open ended, I try to get the activity started and then encourage them to try. For example, I might say, “I am going to place a ramp here, where would you like to place the next ramp?”
Peggy: Do you have any suggestions or resources for teachers?
Sara: Having developmentally appropriate expectations for each student is essential.
Occupational therapist and trainer Dr. Marianne Gibbs’ website, Write Out of the Box, offers developmentally appropriate information on fine motor skills. (Check out the Tips and Teacher Feature pages!) Dr. Gibb’s Handy Handout for Parents, is also an EXCELLENT resource for teachers, about building fine motor skills that will later support handwriting.
Children’s singer-songwriter Nancy Stewart has a fun song and game to play that could go along with the January 2014 Early Years column activity. You could change the words as you teach different shapes, from “rectangles, triangles, circles and squares” to “rectangular prisms, cylinders and cubes.”
Peggy: Thank you Sara, for this information and for being a resource for all the teachers you work with.
I appreciate Sara’s help in recognizing the diversity of student needs in the classroom. “Promoting meaningful and inclusive participation of individuals with exceptionalities in their schools and communities” is an ethical principle for all teachers who work with children with exceptionalities, stated by the Council for Exceptional Children.
As the children and I work with three-dimensional shapes, I remind myself that it takes time to become familiar with any new vocabulary word. Teachers and children may stumble over the words “triangular prism” because they have always said “triangle block” to identify that shape. Posting pictures the geometric shapes along with their names helps readers remember the name and non-readers can refer to a picture.
Here are a few suggestions for teacher resources—books and internet sites—with information and activities to engage children in working in three-dimensions:

The Early Years column in the January 2014 issue of Science and Children, Shape Exploration-Another Dimension.
Sara also shared a game that is a favorite of the children she teaches, “Shape Monster”. The Shape Monster poem is online from several sources as a class book or game. Sara makes shapes – circles, squares, triangles, rectangles in different colors (red, blue, yellow and green) and sizes (big/little). In a 3-D version, the shapes could be balls, blocks, and other geometric shapes. Each child gets a shape or two and then they listen for their shape to be called. The teacher says,
Shape Monster, Shape Monster, munch, munch, munch.
How about a [name of shape] for your lunch?
Each child that has the named shape then gets up and “feeds” the shape monster their shape. The Shape Monster can be a large drawing of a monster face with a wide open mouth, or the children can build a shape monster as they decide where to place their shapes in the center of the circle.
This activity can be differentiated by asking for:
A fun way to be sure all children are included while learning about three dimensional shapes!

This April, the National Science Teachers Association (NSTA) will feature a special strand “Science and Literacy: A Symbiotic Relationship” at our 2014 National Conference on Science Education, in Boston, April 3–6.
Attention to literacy is often seen as taking time away from science. In fact, built right into the Common Core State Standards, ELA, literacy can and should be used to enhance the effective teaching of science. Well-designed and integrated science and literacy instruction creates a symbiosis that supports classroom practice and student achievement. The investigation of science concepts within the elementary classroom enhances the development of reading, writing, and communication skills. At the upper grades, strengthened literacy skills continue to empower all students to access the science content and communicate their understanding. This strand will address how literacy and science are in service to each other across the learning continuum.
Sessions organized around this strand include a featured presentation on Saturday April 5, 3:30–4:30 PM (“Reading and Writing Science: What Should Be My Line?”) by Wendy Saul (Professor and Allen B. and Helen S. Shopmaker Endowed Chair, College of Education, University of Missouri–St. Louis: St. Louis, MO). More sessions on Science and Literacy include the following:
