Marble Runs

Engineers use science and math to solve problems in a creative way. Third grade engineers reviewed force and motion concepts and the Engineer Design Process before constructing marble runs out of recyclable materials- a perfect connection to their current environmental unit. I challenged them to try to construct a run with four turns and at least one jump. This is a challenging task, and students worked collaboratively to solve the problems they encountered during the process. Vocabulary included accelerate, momentum, and inclined plane.

Try this at home!
