In this most recent project we learned about energy efficiency. We had many small projects in this one unit. They were: Solar water heater, cold frame, solar reflector, and an extra bonus project we could choose.
1. The solar water heater was a shoe box with copper wire running through it. we made it on an angle for maximum sun. After 30 minutes our solar water heater raised 3 degrees.
2. In the solar daylighting technique section we designed a house of 1,000 square feet. We wanted to optimize the amount of solar light that went into the house. When we finished the plan we built a small scale model.
3. This section was Wind turbine. In this section we designed and built two wind turbines. One that was horizontal and one that was vertical. My group used cardboard, popsicle sticks, paper, tape , and hot glue. After we completed the building we tested them with a leaf blower. The fan head was connected tot he tester which connected to a motor which had wires that were connected to a voltmeter.
TESTS: horizontal fan head generated 1.12 volts on low, 1.50 volts on medium, and 1.40 on high. The vertical fan head generated .32 volts on low, .46 volts on medium, and .95 volts on high.

4. Cold frame, reflector, bonus plan
For this part of the unit we made a prototype cold frame out of cardboard and seran wrap. Then we we assigned to make a reflector to optimize the amount of light that got through the north window on our STEM house. The last part of this project was to make a bonus plan to further advance our STEM house. My group came up with the idea to put a garden on the roof.
REFLECTION:
Overall I think this project went very well. This was my favorite group so far. We worked very well together and did not argue which made the projects go a lot smoother. On most of the projects we did our best work and were proud. Though we could have done better on our solar water heater.
