This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

Learners use simple materials to construct a model the Big Dipper. Learners hang the model from a doorway or ceiling and look up at it to see the constellation as seen from Earth.

In this activity, learners will swirl paint into shaving cream to make an extravagant nebula print.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

"Exploring the Solar System: Craters" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this activity, learners build a paper model of the spacecraft and photometer (telescope) used during NASA's Kepler Mission.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

This is an activity about turbidity, or the amount of sediment suspended in water.

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.
