Building Building procedureprocedure

We first put on the payload and We first put on the payload and then cut out the cone on the Dixie then cut out the cone on the Dixie cup. The dixie cup was where we cup. The dixie cup was where we

stored the egg. We put cotton balls stored the egg. We put cotton balls around the dixie cup to secure the around the dixie cup to secure the

egg. Then we put 3 fins on the egg. Then we put 3 fins on the bottom of the rocket, and finally it bottom of the rocket, and finally it

was ready to launchwas ready to launch..

Launching Launching procedureprocedure

For air we had to secure the bottle on For air we had to secure the bottle on the pump and the pump it with 80 psi the pump and the pump it with 80 psi air. The we pulled the plug out of the air. The we pulled the plug out of the

rocket, that sent it in the air. For water rocket, that sent it in the air. For water we put 1 cup of water and 80 psi air that we put 1 cup of water and 80 psi air that

we pumped in the rocket. Then we we pumped in the rocket. Then we counted down to 1. When we reached 1 counted down to 1. When we reached 1

we pulled the string and the rocket we pulled the string and the rocket blasted off.blasted off.

PredictionPrediction

We thought the rocket will go faster We thought the rocket will go faster and higher because there will be and higher because there will be

more pressure and the water coming more pressure and the water coming out makes it gain speed.out makes it gain speed.

ComparisonComparison

When we had water in the rocket When we had water in the rocket there was more pressure so the there was more pressure so the

rocket did go higher and faster. When rocket did go higher and faster. When we did the air launch it did not go as we did the air launch it did not go as

high.high.

ConclusionConclusion

We learned that adding water to We learned that adding water to the rocket makes it go faster and the rocket makes it go faster and

higher. We also learned that higher. We also learned that water takes up space so there is water takes up space so there is

more pressure.more pressure.
