Teacher's field guide

What Students Need to Do: Students build diagrams, physical models, or simple prototypes that show how something works. They use labels, parts, and arrows to explain relationships, then improve their work after testing or feedback.
What Mastery Looks Like: A student chooses a model that fits the question and includes the parts needed to explain it. The student can use the model to make a prediction and identify one limitation.
Common Misconceptions: Students may treat a model as a decorated copy instead of a tool for explaining or predicting. They may assume models must be full size, include every detail, or cannot change after testing.
How to Assess It: Ask students to draw a model showing how water moves from a puddle to a cloud. They must add labels, arrows, and one explanatory sentence.

Lesson moves

Build a watershed model from foil, spray it with water, and revise the land shape to reduce flooding near a paper house.
Show two plant growth models and ask, "Which model better explains how roots receive water, and what evidence supports your choice?"
Play Model Match by pairing picture cards of systems with cards showing the processes each model can explain.
Study a local crosswalk problem, then build and test a cardboard prototype that helps pedestrians become more visible to drivers.
