In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.

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 multi-part activity learners examine non-point water pollution.

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

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

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this activity, learners will make predictions and experiment with different objects to see if they sink or float.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners will explore saturated solutions and discover how crystals form.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

In this activity, learners will pretend to be archaeologist using this chilling experience.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.
