Today’s Work Build rockets

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: Construct your own hypothesis

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 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 fins Odd seats = 3 fins Row 1 long barrel rockets – 280mm long Row 2 medium barrels -215 mm long Row 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 is the winner.

280 mm = length of paper. Cut in half length wise. 215 mm = width of paper. Cut paper in half width wise. 140 mm = Fold in half twice, then cut all 4 pieces loose. A ¼ sheet of paper is rolled for the barrel, use the longer side for the length.

Fin construction Use a ruler to measure the 2 sides. Draw the hypotenuse. Cut the hypotenuse. 5 Cm 5 Cm 5 Cm is for the MEDIUM sized, Small =3 cm Large = 7 cm
