In this activity, learners can play two card games related to endangered species, specifically North American amphibians.

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

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

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 chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

This is a series of three quick science activities to do with a spoon, knife, and fork. In the first two activities, learners use the flatware to explore optics, mirrors, reflection, and distortion.

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.

Learners explore their surroundings while reasoning about categories and counting.

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

In this online version of the classic paper and pencil game, learners practice looking ahead to anticipate an opponent's move.

In this activity, learners experiment with inertia by performing an easy and hands-on investigation with a playing card and a stack of coins. The activity includes an accompanying Mr.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or
