Bonus Module: Lenses

This week’s Distance Learning theme is optics, light, and the electromagnetic spectrum.

On Wednesday, we looked at how refraction impacts the way we see an object in water. This module builds on that activity, by using a bowl full of water and a few household props to further explore the properties of lenses.

Stick to just the hands-on activity for younger learners, or bring in the written blog content for middle/high school physics-lovers!

At-home STEM Activities: Calculating the Speed of Light with a Microwave Oven

This week’s Distance Learning offerings are focusing on optics, light, and the electromagnetic spectrum.

It took scientists a really long time to calculate the speed of light—up until 1676 when Danish astronomer Ole Rømer provided the first calculation, scientists weren’t even sure if the speed of light was a finite number. But a few hundred years later, we can calculate the speed of light using not much more than a microwave oven, a bar of chocolate, and a ruler. Let’s try it for ourselves!

At-Home STEM Activities: DIY Spectroscope

This week’s Distance Learning theme is optics, light, and the electromagnetic spectrum. Today we show you how to split sunlight into all the beautiful colors of the spectrum, with a simple homemade spectroscope! This activity takes just a few minutes, and utilizes common household items. Adult supervision is required—we’ll be cutting cardboard with a craft knife.

At-Home STEM Activities: Why is the Sky Blue?

This week we’re diving into wavelengths as we focus on optics and spectra. Let’s start off with something that you may have wondered about, the color of the sky. You might think it has something to do with our atmosphere, and you’d be right- it’s a result of of the interaction between our atmosphere and the light from the Sun. But how does it work?

At-home STEM Activities: DIY Kaleidoscope

We’ve all witnessed the reflection of light. Looking at ourselves in the mirror, seeing sunlight bounce off a pool of water, observing the moon—all of these occur because light is reflecting off of a surface. Light always reflects in the same way, following the Law of Reflection. Basically, the law of reflection says that when light hits a flat mirror, it will reflect at the same angle that it hits the mirror. We can use this law to manipulate light to make beautiful images inside a kaleidoscope! Let’s use some recycled material to make our own kaleidoscopes.
