Projectile Launcher- Marbles!

We created a projectile launcher out of an 8x3 inch piece of wood, PVC pipe, an end cap, spring, marble, tape and nut and ramrod. We created a trial to see how different angles affected the distance. Each angle was different and our data was never very consistent. It was interesting to see that the marble would launch in different spots and it was a good lab. It was beneficial and fun!
