Did your family have a chance to see the total solar eclipse this year? We focused this week’s science experiments on the light, heat and energy we receive from the Sun. We also created a scaled version of totality with a desk globe and a flash light. Our goal is to teach each student the basics of using scientific tools, so children learned how to use thermometers by measuring temperature in degrees Celsius of the room and of hot water. (To our older kids, we explained the difference of measuring temperature vs. measuring heat in joules). Students explored light: playing with laser pointers, they reflected the laser rays with multiple mirrors; created rainbows using old CDs; and changed the color of light emitting from a flashlight using blue or green filters. We gave children a bright flashlight, desk globe and a small ball, and showed them how the moon creates a totality zone on Earth during the solar eclipse. It was a sunny day, so we took solar-powered toys outside and explained how they work.
