Valentine Themed Science Experiment on Light Refraction

Download the printable HERE or draw the design yourself.

Place the paper with the boy and the girl design behind the glass and look through the empty bottle. What do you see ? There is no change, the boy is facing away from the girl.

Fill the glass with water.

Look through the glass of water from the front again and slowly move the paper back, what do you see ? The boy is facing the girl and looks like he is giving her the flowers.

Isn’t that cool.. so grab the printable and give it a try.

The science behind it

When the image is moved to a certain distance behind the glass, it appears to have reversed itself. When light passes from one material to another, it can bend or refract. In this experiment, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before reaching the image. And therefore, it’s refracting.

The glass of water acts like a magnifying glass. When light passes through a magnifying glass, the light bends towards the center. Where the light comes together, it is called the focal point. Beyond the focal point the image appears to be reversed because the light rays bent past each other. The light that was on the right side is now on the left and the left on the right, making the image appear reversed.

I hope you will surprise your special someone with this valentine’s themed science experiment on refraction of light. If you are looking for more science experiment, then check out some of them HERE.
