This is a great way to see how the sun's rays can be turned into thermal energy, useful in our daily lives to cook food among many other things. This activity should be done on a sunny day to ensure that the oven cooks at or above 200 degrees. Take caution! It functions like a real oven, so don't touch!
This is a more advanced activity that uses the same photovoltaic technology as solar panels to convert solar energy into electricity. You can challenge yourself to build a solar car just for fun, but there are competitions that take solar cars more seriously. Check online to see if there are any races happening in your area and see if you measure up to the competition!
