Why Light bends when it passes from one medium (water) into another medium of a different density (air). This bending of light, called refraction, causes the apparent position of the coin to change to a shallower position1 (see diagram). The light bends when it passes from water to air on top of the water. It does…

Thunderstorm Convection Experiment (Video)
Even though there is a severe drought in the area where we live, thunderstorms are still a common spring occurrence. I have shown my kid how rain was created before. Now she’s curious how thunderstorms form and what causes them. So what is a thunderstorm? A thunderstorms is a storm with lightnings and thunders. What causes…
2 Light Refraction Experiments
Refraction Of Light There are so many good refraction of light experiments we want to do. Why: Experiment 1 Light bends when it passes from one medium (air) into another medium of a different density (water). This bending of light, called refraction, causes the straw to look broken1. The portion of the straw that is submerged in water…
Balloon Rocket Car Race | Propulsion STEM Activity
Propulsion And Newton’s Third Law How do airplanes fly in the sky, ships move in the water and rockets take off into the space? These movements all have one thing in common — thrust. Here is a fun science experiment to show how propulsion creates thrust to move vehicles. What you need a toy car(s) (You can…
Color Changing Flowers Science Project
Do you know that flowers can drink up water and change their own colors into the color of the water they drink? Flowers and plants drink water through their roots. In cut flowers, since there are no roots, water travels from the cut directly into the stems and travels to the petals and other parts…
