1. The Exploration of Water Bottle Rockets Mr. Chris Dotson Introduction to Technology and Engineering Concepts (High School Technology)

2. Introduction Who wants to go into space?.... Who wants to go into space?.... Now how many of you like to get wet?.... Now how many of you like to get wet?.... Well a long time ago the Chinese developed rockets so that could use in warfare and the use of fireworks. Well a long time ago the Chinese developed rockets so that could use in warfare and the use of fireworks. But wait, we cant use gunpowder, how will launch a rocket? Lets find out. But wait, we cant use gunpowder, how will launch a rocket? Lets find out.

3. Task It is now your turn to design and build a bottle rocket to launch as high as you can. We will be using soda bottles, water, and air pressure to launch your rocket. First you will need to study aerodynamics and space flight. You will then research many rocket designs that you may want to implement into your rocket. You will ne to use the seven steps of the problem solving process. It is now your turn to design and build a bottle rocket to launch as high as you can.

4. Process The problem: The problem: To design and build a water bottle rocket to compete against your classmate in reaching the highest heights over the school. To design and build a water bottle rocket to compete against your classmate in reaching the highest heights over the school. Be sure you document where you found your material or building instructions. Be sure you document where you found your material or building instructions. Look everywhere, internet, books, magazines, even you classmates or just invent a new designs Look everywhere, internet, books, magazines, even you classmates or just invent a new designs (Remember Do not aim for the police chopper);) (Remember Do not aim for the police chopper);)

6. Evaluation Here is how the points are laid out: Here is how the points are laid out: 25 competition points for best looking 25 competition points for best looking (based on classmates voting 1 st =25, 2 nd =24 and so on) (based on classmates voting 1 st =25, 2 nd =24 and so on) 25 competition points for written explanation of your design, design drawings, and research sources. 25 competition points for written explanation of your design, design drawings, and research sources. 50 competition points for Highest soaring rocket. (h=d*tan) 50 competition points for Highest soaring rocket. (h=d*tan)

7. Conclusion I hope you enjoyed researching, building and launching your bottle rockets. Don’t forget what you have learned from this unit especially the aerodynamics, might fit in upcoming projects. I hope you enjoyed researching, building and launching your bottle rockets.
