Bottle Rocket
Day 1 Log:
May 15th: Today we conducted research in order to create the most effective first model that wold fly the farthest and most efficiently. The research we conducted revolved around the following questions: What is a water bottle rocket? How do water bottle rockets work? How do each of Newton's Laws relate to bottle rocketry? How do the concepts of projectile motion relate to bottle rocketry? How does the Impulse-Momentum Theorem relate to bottle rocketry? Is there an existing design that will work? How might an existing design be altered for improvement? Based on our prior knowledge, and the information we discovered through our research, we created a diagram, that we would use to make our actual bottle rocket in the next class:
We will use 3 fins equally spaced around the base of the bottle, and we will create a paper cone. We would coat the cone, along with the wings with duct tape and hot glue them to the bottle.
Day 2 Log:
May 17th: Today we created or bottle rocket, corresponding to the diagram pictured above.
Day 3 Log:
May 19th: Today we launched our rocket for the first time
Modifications: We aren't going to use hot glue, because it caused the plastic bottle to melt a bit. We are also going to add weight to the front, by sticking play-doh in the front of the cone.
Day 4 Log:
May 23rd: Today we built our second rocket with the corresponding modifications, and tested it.
Modifications: Due to the fact that the cone dented every time we tested it, we decided to hot glue the top 18 centimeters of another 2 liter bottle on the bottom of our initial 2 liter bottle to act as the cone. We also decided to cover all exposed area of the bottle with duct tape, and use 4 fins instead of 3.
Day 5 Log:
May 24th: Today we built our third rocket with the latest modifications, and tested it.
This is our final model
Day 7 log
May 30th: Final testing
