In this chemistry activity, learners make a slimy non-Newtonian fluid called "Gluep." Use this activity to introduce learners to polymers and viscosity.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

Put math of measurement into lining up — and make waiting in line fun. Choose a size characteristic that learners can physically compare, such as foot length or hair length.

In this activity, learners investigate the Earth's rotation and how to tell the time of day without a clock. Thsi simple activity only requires a paper plate, a pencil, and sunshine.

In this activity, learners create a colorful foam fountain by adding yeast to a chemical reaction. This activity introduces chemical reactions to young learners and teaches the concept of catalysts.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

Space Guess Quest is a fun game that encourages participants to identify the many types of objects in space, from human-made spacecraft to nebulas, galaxies, stars, and worlds.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this game, learners use clues to identify mystery shapes. Use everyday objects (like from the pantry) as the shapes.

In this math activity, learners jump and measure how far they can jump on different surfaces using different jumping techniques.
