Scientific Method

• How long will the rocket stay in the air?
• The rocket stayed in the air for 3.64 seconds.
• Will the cotton protect the rocket?
• The cotton did not protect the rocket.

5
Materials Used

• Dixie cups
• Oak tag
• Construction Paper
• Cotton
• Bubble Wrap
• Tape

6
Building procedure

• We first put on the payload and then cut out the
  cone on the Dixie cup. The dixie cup was where we
  stored the egg. We put cotton balls around the
  dixie cup to secure the egg. Then we put 3 fins
  on the bottom of the rocket, and finally it was
  ready to launch.

7
Launching procedure

• For air we had to secure the bottle on the pump
  and the pump it with 80 psi air. The we pulled
  the plug out of the rocket, that sent it in the
  air. For water we put 1 cup of water and 80 psi
  air that we pumped in the rocket. Then we counted
  down to 1. When we reached 1 we pulled the string
  and the rocket blasted off.

Prediction

• We thought the rocket will go faster and higher
  because there will be more pressure and the water
  coming out makes it gain speed.

10
Comparison

• When we had water in the rocket there was more
  pressure so the rocket did go higher and faster.
  When we did the air launch it did not go as high.

11
Conclusion

• We learned that adding water to the rocket makes
  it go faster and higher. We also learned that
  water takes up space so there is more pressure.
