Desalination
Mixtures and Solutions:
Students investigate how various mixtures can be separated. While making a mixture of salt and water, connections are made to global water supplies and the amount of fresh and sea/salt water. Students discuss the importance of water conservation, and how sea water can be "purified" for human consumption.
Students investigate the water cycle, and discuss how rainwater tastes, (or the amount of salt in rainwater). They review the water cycle. Students then use this information to create a device (using solar energy) to extract salt from water and discuss how this device can be used on a large scale to desalinate sea water. As an enrichment activity, students will discuss what other energy sources can be used and how they will source sea water, since Arizona dose not have a sea/ocean border.

As an intro to Thermal Energy, students are challenged to create a warmer that will keep my coffee warm. Students project will be tested in class, data will be collected, compared, and graphed.
Students utilize the Engineering Design Process to create a sailboat! Students must design and build a sailboat that will get them from one end of the channel where they are stranded to the other. It
This is a continuation of lesson 1 and 2. Students will learn about kinetic vs. potential energy and apply that knowledge to their car designs.
