Bubbles and heat
Energy can be generated in so many ways. Try this energy experiment to explore a chemical reaction. This experiment uses materials you can find around the house. You will mix two substances to make a third. Heat will be a factor as chemical energy. What do you think will happen when you make the mixture? Safety note:…
Comparing light bulbs STEM energy activity
Choosing light bulbs for your home has changed so much in the last ten years. How do you decide what’s best? Here’s an experiment children can do comparing light bulbs. Which makes the most sense for the family? Congress passed a law in 2007 that phases out the US production of incandescent bulbs. The old-style tungsten-filament…
Solar beads ultraviolet detection STEM activity
Solar beads are a fun way to learn about the importance of sun exposure. We should put on sunscreen every day and think about reapplying it. We can teach children a craft project with pony beads and experiment with the UV rays given off by light sources and test sunscreen products for effectiveness. This post contains…
Solar energy activity – solar panel & motor
Use the sun’s power for this solar energy activity. Solar panels use semiconductor material that converts light energy to electricity. An electric motor helps you to see the electricity being produced! Safety note: Be sure to explain safety precautions to children. Solar energy activity involves electricity and heat. Eye and skin protection should be used. When…
