Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In this activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.
