In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this forensics activity, learners solve a mystery using “DNA” taken from the scene of the crime.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this math activity, based on the research of famed astronomer Frank Drake, learners calculate the possibilities of finding intelligent life elsewhere in the universe besides Earth.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

In this interactive game, learners listen to the songs of four different thrushes and then try to match each bird with its song.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
