  1. CITY SCIENCE STARS: Kick-off to Lift-off

  2. SHOOT FOR THE MOON! What forces are involved here?

  3. HOW DO ROCKETS WORK? LIFT DRAG THRUST GRAVITY Isaac Newton’s Laws of Motion Published in 1687

  4. WHERE DID ROCKETS COME FROM? China Year ~1200 Germany WW2 Global Modern era

  5. BUILD YOUR OWN PAPER ROCKET! Body tube (room for engine, fuel and cargo) Nose cone Mission logo Exhaust nozzle (hole for launcher) Fins

  6. EXPERIMENTAL DESIGN To design a fair rest, each team should pick one factor to vary and keep the rest the same • Length of rocket • Weight of rocket • Number of fins • Size or shape of fins • Shape of nose cone • …something else?

  7. EXPERIMENTAL DESIGN 1 - Low launch trajectory (pass) 2 - Medium launch trajectory (shot) 3 - High launch trajectory (lob)

  8. ROCKET LAUNCH EXPERIMENT Let’s go launch some rockets!

  9. ROCKET LAUNCH EXPERIMENT • Which angle sent the rockets the furthest? • Which design sent the rockets the furthest? • What could we do to improve our designs? • How might real rockets generate thrust?

  10. FIZZ, BANG, ZOOM! – ROCKET CHEMISTRY • Stomp-rockets get their driving force from air in the launchers pushing them forward, but where does the thrust for full-size rockets come from? • Chemical rocket engines rely on the combustion (burning) of fuel to create exhaust gases that fire out of the bottom!

  11. WHAT HAVE WE LEARNED TODAY? • The forces involved in kick-offs and lift-offs • How to build and launch paper rockets • How design and angle affects performance • How chemistry makes rockets go with a bang!
