Sure, here are some more exciting ideas for elementary school physics projects:

1    Rocket Launcher: Build a rocket launcher using PVC pipes and launch water rockets, experimenting with different fins, nose cones, and payloads.

2    Roller Coaster: Build a roller coaster out of foam tubing and investigate the physics of motion, such as velocity, acceleration, and friction.

3    Rube Goldberg Machine: Create a Rube Goldberg machine that accomplishes a simple task using a series of chain reactions and investigate the principles of energy transfer and mechanical advantage.

4    Electric Circuit Maze: Design and build a maze that requires an electrical circuit to navigate, using wires, batteries, and light bulbs.

5    Laser Maze: Create a laser maze using mirrors and investigate the properties of light, such as reflection, refraction, and diffraction.

6    Sound Wave Visualizer: Create a visualizer that displays sound waves using a strobe light, a speaker, and a water stream.

7    Wind Tunnel: Build a wind tunnel to test the aerodynamics of different shapes and objects, such as airplanes, cars, and buildings.

8    Magnetic Levitation: Build a levitating train using magnets and investigate the principles of magnetic attraction and repulsion.

9    3D Printing: Use a 3D printer to design and build a working machine, such as a wind turbine or a robotic arm.

10    Augmented Reality Sandbox: Create an augmented reality sandbox that visualizes topography, water flow, and erosion using a Kinect sensor and a projector.
