Cell Comparison Chart
25 minStudents draw and label a plant cell and animal cell (8 organelles each). Create a comparison chart: same vs. different.
Experimental Design Practice
25 minProvide a science scenario. Students identify independent variable, dependent variable, control, 2 constants, and write a hypothesis.
Food Web Construction
25 minStudents choose an ecosystem and draw a food web with at least 10 organisms. Label producers, primary consumers, secondary consumers, and decomposers.
Rock Cycle Diagram
20 minStudents draw the complete rock cycle, label the 3 rock types, and explain the process for each transformation (3 sentences minimum).
Chemical vs. Physical Change
20 minStudents list 10 changes from everyday life and classify each as physical or chemical. Write the evidence for each classification.
Tips for the Substitute
- •Diagrams should be large, labeled, and detailed
- •Challenge: color-code diagrams by category
- •Pair students to explain diagrams to each other

Frequently Asked Questions
Can students do science activities without lab equipment?
Yes — all these activities use pencil and paper only. Science thinking (observation, inference, analysis, modeling) doesn't require a lab. These activities focus on the cognitive science practices.
What if students haven't covered a topic yet?
Tell the sub to let students choose a science topic they HAVE covered. Most activities are open-ended enough that any science content works.
