DIY Sun Science is a free iPad app from The Lawrence Hall of Science. The app features directions for hands-on lessons about the sun. The lessons are a mix of activities that students can do on their own and activities that they should do with adult supervision. All of the activities use common household goods. Some of the activities that you will find in DIY Sun Science are measuring the sun, making UV detectors, detecting solar storms, and cooking with a solar oven.
At the end of the directions for each activity in DIY Sun Science you will find short video lessons related to the focus of the hands-on lesson. You can also just jump to the video section of DIY Sun Science to access the videos without going through all of the directions screens.
