This Hands-On Wednesday blog requires adult supervision. Make sure to conduct this experiment with help from a parent or friend. Electrical currents aren’t the only thing that can make a light bulb glow — follow these steps to see what microwaves do when passing through the tungsten filament of a light bulb. The results may surprise you!
Today’s activity doesn’t require a lot of materials, but it’s a great test for your senses! Our muscles, tendons, joints, and inner ear all contain what is called proprioceptors. These ‘stretch receptors’ help us know positional locations, which means that we have a sense of where our hands, fingers, and other body parts are in relation to the rest of our body and the environment around us. See how well your proprioceptors are working by completing a few simple tasks with your eyes shut.
