In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this "game," learners explore and relate the evolution of stars to a Navajo creation story. The story is written on a series of cards, which are laid on a table as the story is told.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

Discover how a refracting telescope works by making one from scratch using common items. This telescope won't have a tube so the learner can see how an image is formed inside the telescope.

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

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, 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.

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

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

In this activity, learners use a simple 3D model to discover why the Moon has phases.

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.
