1. WATER ROCKET EVALUATION LESSON AND NOTES
Matter - Material - stuff
Measure
Transportation Technology Mass Weight Gravity Force
Pressure Thrust Propel Accelerate Balance
Diameter Circumference Aerodynamic Drag
Different/Better
Mass x Gravity
Attraction - pull
Push - Pull
Change
Move
Quick – Sudden
Burst
Increase, Decrease speed or Direction Change
Straight – Steady
Stable
Force / Area
Make move
Widest - Center
Around - Perimeter
Shape – Cuts
Slices
Air Friction/Resistance Rubbing - Slows
CRAZY TO NOT TAKE DOWN WHAT’S IN RED!!

2. 1. Explain what might happen if a rocket had only TWO fins?
(Balance --- Drag)
2. Describe/explain the CHANGES you could make to improve upon your launch results?
Pointy Nosecone – Seltzer/Soda – Increase Pressure – Modify Fins - Adjust Mass
3. LIST Newton’s three laws of Motion!
(See bulletin board poster)
4. WHAT are at least four CHARACTERISTICS/FEATURES that would lead to any object moving well?
Balance – Low Mass – Aerodynamic – Greater Force/Pressure/Thrust
5. WHAT are the two PURPOSES of the Ping-Pong ball?
Up = Aerodynamics Down = Parachute/Drag

3. Water down/out slow = Rocket Up Slow
6. Explain why/how a LIGHTER rocket should be more successful than a HEAVIER one?
Less Mass & Same Pressure = Greater Acceleration/Propulsion
7. Explain what would occur if only 75lbs. of pressure were pumped into the soda bottle.
(Think 2nd Law of Motion)
Less Pressure = Less Force/Thrust = Less Acceleration/Propulsion
8. Explain what would occur if the soda bottle were filled with water, instead of using only one cup of water.
(Think 3rd Law of Motion)
Water down/out slow = Rocket Up Slow
