Submarine Project
Mission: My mission was to design, construct, and demonstrate a submarine device that floats, sinks, then floats again in a tank of water. The objective of the project was to demonstrate Archimedes' Principle and calculate the changing density of the sub. The entire design process was recorded in my Captain's Log.
Problem Statement: How does the design of a submarine affect how it floats or submerges in water?
Hypothesis: If the submarine design includes a chemical reaction, then the submarine will float back to the surface because the gas produced during the reaction will make the submarine less dense than the surrounding water.
Criteria: Design, construct, and demonstrate a device that floats, sinks, then floats again in a tank of water.
Constraints:
Students also had to present their project to the class in English class for a presentation grade. The English teacher worked with the students on eye contact, rate of speech, and using multimedia as visual tools.
Students were given a list of multimedia tools to choose from: Weebly, Google Sites, Prezi, Glogster, Discovery Education Board Builder, Educreations.

Criteria: Design, construct, and demonstrate a device that floats, sinks, then floats again in a tank of water.
Constraints:
- Device must be more than 5 cm long and not larger than an average shoebox.
- Sub has 5 minutes to complete its mission.
- The sub itself may not be touched once inserted into the tank of water.
- The density of the water in the tank must remain unchanged after your sub has completed its mission. Things that dissolve in water are not allowed.
- 2 class periods to research and design the sub, 2 days to construct the sub, 2 days to test/redesign prototype.
- The only materials provided by the teacher: 1 water bottle, 1 straw, 1/4 stick of clay, 50 cm kite string
