Investigating How Our Designs Work

Students introduce themselves and their communities to the partner class through a video call, then see their plank car models and learn about the investigation goals.

In small teams, students change one design feature at a time, run controlled roll tests, and record distances and times in a shared data table with the partner class.

Students review both classes' data together, identify which design choices performed best under different conditions, and explain why they think the results happened.

Teams choose a community profile, such as a rainy mountain town or a dusty city street, and decide which plank car design choices would work best there, using evidence from the shared data.

Teams share their test results, community recommendations, and reflections on what they learned about working across cultures during a joint showcase.
