1. Model Rockets By: David Bivens

2. Big question Does size change the height of how high it goes? Because rockets come in different sizes.

3. Hypothesis I think the taller the rocket the higher it goes. I think this because the rocket is higher and can reach a higher altitude.

4. 5 interesting facts 1.There are more than 300 types of rockets 2.The smallest rocket is 6 inches 3.Rockets are more than 2000 years old 4.Some rockets take 4 or 5 years to build 5.The largest rocket made in the US was the Saturn V

5. Experiment Materials Model rockets (small, medium, and large) Binoculars Launch pad Something to record data I had no control groups or variables. Step by step instructions 1.Get all the materials. 2.Build the rockets. 3.Set up the launch pad. 4.Launch the rockets. 5.Look through the binoculars and at the highest point write down the estimated height.

6. Data

7. Analysis of data Yes my experiment tested what I wanted to do. I know because I could estimate the height of the rocket.

8. Conclusion No, my hypothesis was not correct because the shorter one went higher. I would change the rocket engine types and see if that does anything.

9. Questions I had 1.Would weather change the results? 2.Would wind change the results? 3.Would the weight change the results?
