In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

Learners will explore the concept of angular distance, and investigate why the moon appears to be the same size as the sun during a solar eclipse, despite the sun being much larger.

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

This is a lesson plan for an activity in which learners, playing the role of archeologists, use math concepts about number bases to decipher the Dresden Codex, an ancient Mayan document.

In this activity, learners recreate the lunar phases using the frosting from Oreo® cookies and place the phases in order. Round cream cheese crackers can also be used if cookies are not an option.

In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.

The "Exploring the Solar System: Magnetic Fields" activity shows participants how scientists can use tools to study the invisible magnetic fields of Earth, the Sun, and other objects in the universe.

In this online interactive challenge, learners choose items to represent the Earth or solar system, then determine other items to represent the Moon, or Milky Way based on their relative size.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

In ancient Chaco Canyon, the people used a "sun dagger" petroglyph to mark the passing of seasons.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

Exploring the Solar System: Solar Eclipse” is a hands-on activity demonstrating how the particular alignment of the Sun, Earth, and Moon can cause an eclipse.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
