Not strictly speaking rockets, actually projectiles. Make a compressed air rocket launcher from plumbing parts. The rockets are made from paper /card and sellotape. They are easy and cheap to make in class. Amongst other things, you can change the weighting; position of fins, number of fins, shape and size of nosecone on the projectile and the pressure and angle of firing can be changed on the launcher.-Ideal for investigations.
These rockets will spectacularly easily travel 100m.
The Rocket launcher is made from copper pipe with plumbing fittings (each launcher worth about €40 in materials)
IoPI supply all materials and tools needed. Participants construct and take their launcher back to school.
This workshop will accommodate 20 teachers. Advanced booking is essential.
