Water heater lab: Description of what we did: For this project we were supposed to heat up the water. We used copper tubing, plastic tubing and a water jug. The water goes through the plastic tubing into the copper tubing and heats up. We chose the copper because it is a good conductor of heat. Then we waited outside for 30 minutes and the temperature increased quickly. The final temperature increased by 11 degrees C.
How we first started working on the outdoor classroom was by finding a spot for it. Our site we selected was the box next to the cafeteria. We thought this site we selected would be best because it is close to the cafeteria and easy access to San Marin students.
We then surveyed teachers and students for what features they wanted for the outdoor classroom. They wanted a shady spot and wanted to use it for a lounge and they also wanted wifi. Then we searched for materials that would be used best for the outdoor classroom and we found that pressure treated wood would work the best in the outside environment. We would use a tarp for the roof. Chicken wire for the flooring so the squirrels wouldn't tear the floor up.
For our presentation we had a slideshow that had a 3D model of the structure and the blueprints of it. In my opinion I thought this was a tough project and it was hard to keep focused during it, but it made my group work more as a team when they got me and others on task.
For the wind turbine lab we made VAWT (vertical propellers) and HAWT (horizontal propellers). We made paper and metal propellers and the metal ones worked the best.
