Today’s Homework Astronomy night postponed to next Wednesday

Today’s Class •No Safety Test? NO rocket launch! Come in before school, after school or lunch. •Build Rockets

Mental Notes

There is no making up work after May 29, end of triad. (28 class days).Make up triad 5 work by May 1 for credit.

Notes

Stomp Rocket Lab Observed: Pieces of notebook paper can be crafted into a missile powered by compressed air. The compressed air can be created by stomping on an empty soda bottle. These rockets can fly quite far. Various designs may affect the distances achieved.

Question: Can we develop a design that maximizes the distance a stomp rocket will fly horizontally?Prediction: If trained students guide others in the design and construction of stomp rockets, then we will be able to test different rocket designs to determine which design maximizes horizontal flight distance.

Hypothesis: The best designs will exceed 40 meters horizontal flight distance.

Tools – ROCKET construction: a) white notebook paper for barrel; b) ¼ sheet of paper for nose cone; c) large or small squares of construction paper for fins; d) cellophane tape. STOMP BOTTLE construction: 2 L. soda bottle; 30 cm. drip hose; 60 cm duct tape.

Procedure: Construct rocket using white notebook paper for the barrel. The barrel opening must allow the drip hose to be inserted. The nose cone must be sealed around the tip and the joint with the barrel. The stabilizing fins may be large, small, or a combination of each. 3 or 4 fins per rocket. Put your name on the rocket barrel and fins.

Rocket configuration: Even seats = 4 finsOdd seats = 3 finsRow 1 long barrel rockets – 280mm longRow 2 medium barrels -215 mm longRow 3 Short barrels = 110 mm long

Once complete, place rocket on inflated bottle launcher, inserting the drip hose about 6 cm into the barrel. Hold hose in a 450 angel to the ground. Stomp on the middle of the bottle. NOTE! DO NOT STOMP ON THE BOTTLE ENDS. Allow the rocket to settle on the ground. The farthest distance will be marked. If time allows, a second attempt for distance shall be completed. Longest distance wins.

Longest distance is the winner.
