My colleague and I are early–career science teachers at a middle school. Rather than our reinventing the wheel, do you have any suggestions how to make lab days run more smoothly, especially at the beginning and end of the class?
–Sean, Oakland, California
To ensure lab periods run smoothly (and safely), planning and preparation are essential. Every activity should relate to your learning goals and be appropriate for your students’ experience level.
Review the activities or investigations thoroughly to determine if you have the proper facilities, time, and materials to conduct them safely. Put yourself in the role of a student. What could possibly go wrong? How much guidance and support will students need? Never have the students perform a procedure that you have not tried or are familiar with yourself.
Plan activities for the amount of time you have. If you have a single period, choose investigations that can be completed (including the introduction and cleanup) within that time or that can be paused and continued at another time.
Assemble materials and equipment in advance. Have extra supplies on hand, so you don’t have to leave the room to get something. Assemble trays or boxes with materials for each group (I numbered the boxes to match each team). An “inventory” card in the box or note on board helps students know what should be in the box. Assign a student on each team the role of equipment manager to get the materials and alert the teacher if anything is missing.
Prepare students for the activity by reviewing the purpose, procedures, and safety issues. If students designed the procedure, check their ideas by having them show you their proposal before they start.
Monitor your students as they work. In addition to looking for safety issues or off-task behaviors, this is an opportunity for formative assessment. You can ask or answer questions, guide their thinking, and eavesdrop on their conversations as they work. You can have a list of lab skills and check off students as they demonstrate them. Also note anything you want to change for the next class or the next time you do this activity.
Even your best class can run into difficulties. Never leave the room or be distracted with emails or phone calls while students are doing an activity. Accidents can and do happen, but you don’t want students to hide broken glass or clean up a spill with a sleeve. Deal with the situation right away in a matter-of-fact style.
If a student is engaging in potentially dangerous behavior and does not respond to your guidelines, remove him/her from the situation immediately, stopping the entire class if necessary.
Time flies during an activity, and if the bell rings while students are still working, they’ll want to rush on to their next class. Students must assume responsibility for cleaning up at the end of the period so everything is in place for the next class. Set an alarm or timer so there’s enough time to clean the workstations and debrief on the activity.
Have a sign at each lab station with a list of cleanup tasks. The equipment manager on each team should make sure group members complete tasks such as returning the materials to the boxes, wiping the tabletop, cleaning the glassware, turning off or resetting probes and other instruments, discarding any trash in the proper receptacle, and following other directions you may have (such as sterilizing and storing eyewear).
Boxes should be returned to a designated place where you can see the contents. Pay attention to forceps, calculators, scissors, and other items that may “disappear.” Note if anything is broken. Establish a routine in which students wait until you are satisfied things are in order for the next class before leaving. (This should be the routine on non-lab days, too!)
At the end of the day, return materials and equipment to their proper places if the activity is completed. If you’re continuing the activity, put the boxes in a secure place. Annotate your lesson plan with any concerns or ideas for next time. Update the inventory with how much of a material was used or if anything was broken or discarded.
This was an area in which I struggled at first. But with organizational strategies and routines, I found lab days were enjoyable and challenging for both the students and the teacher!

Patterns…cause and effect: mechanism and explanation…scale, proportion, and quantity…systems and system models…energy and matter: flows, cycles, and conservation…structure and function…stability and change…
How does your science and engineering teaching involve concepts that cut across many science disciplines and are central to the K-12 Next Generation Science Standards (NGSS)?
These seven crosscutting concepts are presented in the document that framed the NGSS, A Framework for K-12 Science Education: Practices, crosscutting concepts, and core ideas (NRC 2012) and were previously identified in some form in Science for All Americans (AAAS 1989), Benchmarks for Science Literacy (AAAS 1993), National Science Education Standards (NRC 1996), and NSTA’s Science Anchors Project (NSTA Press 2010).
The seven crosscutting concepts presented in Chapter 4 of the Framework are as follows:
1. Patterns. Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them.
2. Cause and effect: Mechanism and explanation. Events have causes, sometimes simple, sometimes multifaceted. A major activity of science is investigating and explaining causal relationships and the mechanisms by which they are mediated. Such mechanisms can then be tested across given contexts and used to predict and explain events in new contexts.
3. Scale, proportion, and quantity. In considering phenomena, it is critical to recognize what is relevant at different measures of size, time, and energy and to recognize how changes in scale, proportion, or quantity affect a system’s structure or performance.
4. Systems and system models. Defining the system under study—specifying its boundaries and making explicit a model of that system—provides tools for understanding and testing ideas that are applicable throughout science and engineering.
5. Energy and matter: Flows, cycles, and conservation. Tracking fluxes of energy and matter into, out of, and within systems helps one understand the systems’ possibilities and limitations.
6. Structure and function. The way in which an object or living thing is shaped and its substructure determine many of its properties and functions.
7. Stability and change. For natural and built systems alike, conditions of stability and determinants of rates of change or evolution of a system are critical elements of study.
These science and engineering concepts are part of early childhood learning. Early childhood educators teach their students to make patterns—ABAB, AABAAB, ABCABC—and to observe patterns—the sky is cloudy when it is raining, day follows night follows day, most leaves are green. We help our students investigate causes of events—pouring for a long time may overflow a container, the isopod/pillbug rolls up when touched, the playdough dries up when the lid is left open.
Children are beginning to learn about measurement of time and objects through experiences in early childhood, and learn about systems as varied as magnetic train and track sets and pollinators’ relationship with flowering plants. Caring for living organisms such as bean plants and fish teaches children that they need food (energy) of some kind to survive. Another early experience with energy is feeling the warmth of sunlight on their skin and feeling cooler in the shade. Building blocks, a staple of kindergartens since they were first organized, provide children with many experiences with stability. Pairing blocks with a ramp opens the door to exploring how changes in ramp position affect the motion of objects moving down the ramp. Making a change in matter through cooking is another way children explore change in the early years.
Our conversations and discussion with children can help them make connections as we ask them to tell us what they are thinking and how they came to that understanding.
The editors of the National Science Teachers Association’s elementary journal, Science and Children, put out a call for papers on the topic of crosscutting concepts for journal issues in the 2014-2015 school year.
How are children in your program expanding their understanding of these concepts that cut across the different areas of science? The deadlines to submit your manuscript are March 1-November 1, 2014. I’m looking forward to learning from you!

This month’s guest editorials address the theme of science for ALL students:
For some of out students “hands-on” can be a challenge. The authors of Let’s Get Physical* show how they adapted two elementary science investigations (egg drop and plant growth) to include accommodations and suggestions for students with cognitive, physical, and sensory disabilities so they could fully participate. The suggestions could apply to any grade level and activity! [SciLinks: Learners with Disabilities]
Kindergarten students find out What’s the Weather Like Today?* with lesson ideas and strategies designed to reach students of all abilities. Focusing on wind patterns, students gather and chart data. Eventually they also collect and chart data on temperature and precipitation. The authors describe how the lesson uses trade books and can be adapted for students who use assistive technologies or have visual impairments. Watching the Wind* features several trade books and lessons that help children focus on what the wind can do so they can understand that wind has power and can be used to simply blow items around (K-2) or generate wind power through building windmills (3-5). The lessons include links online resources and connections to Common Core and [SciLinks: Winds, Weather]
Students come to our classrooms with varied experiences to build on: cultural backgrounds, ELL, reading level, learning preferences, age, and a range of abilities. Assessment for All discusses how formative assessment probes can address all students and ways teachers can adapt them to meet the diverse needs within their own classrooms.
Watching the Wind* features several trade books and lessons that help children focus on what the wind can do so they can understand that wind has power and can be used to simply blow items around (K-2) or generate wind power through building windmills (3-5). The lessons include links online resources and connections to Common Core and [SciLinks: Winds]
NGSS for English Language Learners* addresses the question of how to get ELL students to engage in scientific argumentation. When a lesson did not go as intended, the authors revised their thinking with reflection on NGSS goals, planning and practice in designing a lesson on forest ecosystems.
Most teachers appreciated the role of visualization in learning. The authors of The Power of Multimodal Representations* share research findings on the effectiveness of visual supports with students with learning disabilities and with emotional or behavioral disorders. They provide several examples of concept maps and student-generated drawings and photographs. The article also includes a template for a claims-and-evidence discussion
Do you have a family night or similar event for students and parents? The authors of Culture Matters in Science Education* describe a multicultural “festival” that engaged students, parents, and the community. The article also discusses the concept of “culturally relevant teaching” in terms of the diverse ethnic, cultural, linguistic, and religious backgrounds of students.
Using the school yard as a resource and building on their prior experiences, students investigated renewable and nonrenewable resources as described in Learning Science in Cultural Context*.
This month’s Early Years column, Shape Exploration: Another Dimension* has suggestions for young scientists to explore three-dimensional shapes.
*And check out more Connections or this issue (January 2014). Even if the article does not quite fit with your lesson agenda, there are ideas for handouts, background information sheets, data sheets, rubrics, and other resources.

Talking with other early childhood educators enriches my understanding of how children learn and I often learn good ideas for teaching about particular science concepts. I had an online conversation with Mary Myron who I met at the 2013 annual conference of the National Association for the Education of Young Children. Mary has held several positions in early childhood, has a Master of Education in Early Childhood and is a National Board Teacher in Early Childhood. She is now the Mentor Kindergarten Instructor at the East Tennessee State University’s “University School” and an adjunct faculty member, with a wealth of experience as a lead teacher in early childhood programs.
Welcome Mary!
Peggy: At what age should children begin learning science and engineering concepts?
Mary: Children start on their own at birth! They are curious scientists and use all their senses to figure out how it all works.
Peggy: Can you describe an “ah-ha!” moment for you as a classroom teacher when you noticed a particularly effective technique for helping children understand science concepts?
Mary: I don’t remember the exact moment but I do remember when I was working with fellow educators to explore and absorb Reggio experiences. The projects that the Reggio children were involved in went in so many different learning directions—I wondered how will I manage this? It was shortly thereafter when I realized that I was a co-learner and co-researcher with the children and could joyfully participate with them. For me the ah-ha discovery was really listening to them and respecting their questions…then facilitating their search for answers and understanding using the scientific process (on their level of course)
Peggy: What is a memorable, or current, science investigation that your preK or K students took part in?
Mary: I would be happy to begin with a memorable one, the Bird Project. It has been to date the longest and most in-depth project I have been involved in. This does not in any way diminish others that are not as long but it was such an amazing experience that I love to share it. If I may, I will just describe what happened.
For curriculum planning purposes, I use an over-all umbrella theme for a period of weeks or even months. It is always a science related theme and usually has to do with the changes that are occurring out of doors in our northeastern Tennessee environment. I select these themes because they are meaningful and relevant to young children as curious scientists.

You’re barely in the door of your local sporting goods store before you’re bombarded with displays of clothing designed specifically for every sport—even fishing! Are you better at any one of these sports when you’re wearing the specially designed togs? Maybe—maybe not. But in sports where gold medals can be determined by hundredths of a second, the well-placed seam can make a difference! Delve into the design of those seams and fabrics by watching Shani Davis & Engineering Competition Suits, part of the latest “Science of…” series from NBC Learn and partner NSF. In this series the 2014 Winter Olympic Games becomes a backdrop for furthering your STEM efforts.
NSTA joins the team as well, with video-connected STEM lesson plans brimming with ideas for science and engineering design inquiries and activities focusing on math and technology. Download the lesson plans at the links below. When you open them, you’ll see that some are labeled grades 4–12 and others are labeled 7–12. Note that the writers are always targeting middle school, but, depending on the sophistication of the video’s concepts, many of the connections, suggestions, and activities can be scaled up or down for your students.

I feel overwhelmed by the grading process. It seems like I spend most of my waking hours grading homework, lab reports, tests, quizzes, notebooks, and projects. I teach two science courses at the high school and meet 150 students every day. What can I do to use my time better and meet the deadlines?
—Stacy, Seattle, Washington
One of my big “aha” moments when teaching 150 students was a realization that different types of assignments required different levels of my attention. It’s important to identify activities and assessments that demonstrate students’ understanding of a concept or their ability to use a process. These require time for in-depth evaluation.
But teachers can overwhelm themselves with trying to evaluate and designate points to every piece of student work. The real value of in-class assignments, homework, and formative assessments is in how they contribute to student learning, rather than how many points they’re worth. I know teachers who select student work randomly to get a sense of what students understand. (They explained this strategy to the students in advance.) Some teachers check off completed assignments before discussing them in class. The teachers recorded which students completed the task and students had the opportunity to update or revise their work.
Explain to students you need time to examine their efforts on projects and written work carefully and respond thoughtfully. For example, you could divide tests into two parts: an objective part and an essay part. The first could be returned and discussed quickly (even the next day), but the essays could take longer to read and comment on. I assigned a score for each, showing students the essay part was just as (if not more) important as the objective questions.
For lab reports, borrow the idea of “Focus Correction Areas” from our language arts colleagues. Instead of trying to review the entire report, focus on one or two key areas, such as the research question/hypothesis, data tables, graphs, illustrations, or conclusions. Glance through the rest of the report for any glaring errors or omissions if you like, but concentrate your comments on these areas.
Differentiate between proofreading and providing feedback. Part of your rubric for major assignments could be “clarity of communication,” but correcting every spelling or usage error on every assignment takes away time from providing constructive comments related to the science goals (and could discourage students from writing).
Feedback should focus on what specifically the student did well, point out where the student may have made errors or demonstrated incomplete thinking, or discuss how the student could improve. With 150 students, it would indeed be overwhelming to write a detailed analysis for each student. Rubrics can be used to provide feedback, showing students how they performed on components of the task, giving you time for more personalized comments.
Use science notebooks as much as possible. Each week, review a few from each class or focus on a key assignment. Have students include their vocabulary, notes, graphic organizers, summaries, or bell-ringers and review them holistically instead of individually. During lab or small-group activities, spend some time with each group to observe their work and do a quick scan of their notebooks.
With two different subjects, you have some options to help yourself. Don’t give tests in both subjects on the same day. Give yourself some breathing room in terms of doing labs, too. Assign projects in your two subjects at different times.
And take a break from the paperwork once in a while to clear your head—exercise, read a novel, do some yard work, visit a coffee shop, or do something fun with your family or friends. Your health and sanity are just as important as today’s science quiz.
