Wonder Project: Rocket Challenge
Year 6 STEM Adventure Exploring the Science of Flight Building and Testing Our Own Rockets
What Makes Things Fly?
Think about objects you've seen flying What forces are at work? How do rockets differ from airplanes?
The Four Forces of Flight
Thrust - pushes forward Drag - pulls backward Lift - pushes upward Weight - pulls downward
Rockets vs Airplanes
{"left":"Use jet engines for thrust\nNeed air to fly\nHave wings for lift\nFly in atmosphere","right":"Use rocket engines\nCarry their own oxygen\nNo wings needed\nCan fly in space"}
Balloon Rocket Demonstration
Blow up a balloon Hold the opening closed Let go and observe What happens and why?
Newton's Third Law
For every action, there is an equal and opposite reaction - Sir Isaac Newton
How Rocket Engines Work
Fuel and oxidizer mix in combustion chamber Burning creates hot expanding gases Gases shoot out through nozzle Rocket pushes forward by Newton's Third Law
What Makes a Good Rocket Design?
Think about shape and size What about weight? How important is the nose cone? Where should the fins go?
Rocket Design Principles
Pointed nose cone reduces air resistance Body should be lightweight but strong Fins provide stability and direction Center of gravity affects flight path
Paper Rocket Planning
Draw your rocket design Label the nose cone, body, and fins Predict how it will fly Share ideas with a partner
Materials for Our Rockets
Paper tubes for the body Cardstock for fins and nose cone Tape and glue for assembly Film canister for propulsion chamber
Safety First!
{"left":"Always wear safety glasses\nKeep workspace clean\nUse tools properly\nFollow teacher instructions","right":"Launch only in designated area\nNever aim at people\nWait for all-clear signal\nRetrieve rockets carefully"}
