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 the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

In this activity, learners examine nanoscale structures of common things.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners build a LEGO® structure while wearing mittens. This activity shows learners how difficult it is to build small things when your tools are too big.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity, learners concoct some stretchy green goo called Gak. This activity will introduce learners to polymers, chemical reactions, and how scientists invent new materials.

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

In this activity, learners will explore surface tension, what it is, and how we can change it.

In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?

In this activity, young learners will experiment with a basic chemical reaction and observe what happens when gas gets trapped! Activity includes step-by-step instructions, safety notes and more.

Build a car that runs on air. Using household materials, experiment with the power of air to create thrust powerful enough to move a homemade car.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

In this math activity, learners play a game and try to collect the most cards by guessing if the next number to appear will be odd or even.

In this activity (2nd activity on the page), learners explore the sensitivity of their sense of touch.

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.
