4. First we got our bottle. Then we cut out our wings or fins. Then we taped them on. We built a capsule out of some sort of a cylinder thanks to Ally's dad. Then after we worked on it we taped that on too.

6. Scientific method (state the problem) 1. Can our water rocket go higher? 2. How can we keep our eggstronaut protected?

7. 1. Made a design 2. Got materials 3.Got the soda bottle 4.Made a capsule and stuffed it with cotton balls 5. Made 4 fins and put them on

8. 1. We put 1 cup of water into the rocket. 2. Then we put the plug into the soda bottle. 3. We pumped 80 psi’s into the bottle. 4. We pulled the string that was connected to the launcher and it went into the air!

9. We predict that the water rocket will launch higher than the air rocket because I think it will give it a little more push.

11. The reason why the water and air rocket are a lot different is because the water rocket goes higher and the air rocket goes lower. The water rocket went higher because there were 80 psi’s of air that take up a lot of space, so when we added water there was barely any space left!

12. In science we learned that when you pump 80 psi’s and pour one cup of water in the rocket it gets more pressure so it can go higher. When you put in just the air in, it doesn’t get as much pressure as it does with the water in it.
