7.1: Forces & Motion 3 Dimensions & Progressions

Unit 1

●​ I can provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object.

●​ Students use a balloon rocket, and change variables (shape, size, weight) to explore how

●​ Under Pressure: Launch a Balloon Rocket ●​ Use Micro:bit Counter to measure ●​ Balloons (various shapes and sizes), Plastic Straw, Tape, Stopwatch (optional), Weights (optional) Note: Weights can be added to balloons for more in-depth exploration, Veneer Probes (optional), iPads (optional)
