Now that we are at the end of the course, we just finished our unit on electricity. If, for some reason, you are not satisfied with your class grade, here is an extra credit project that can add points to you final class grade. Build a lemon battery. It will take a little time and money (you have to buy the lemons etc.), but it will be worth it. Follow the instructions in the video below.
Build your battery, show that it works, add 5 points to your final class grade.
To buy a low-voltage LED, try Farm Electric Inc. at 1045 Baxter Street. phone # 706-543-5280.
