In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

This is an activity to do when there is a solar eclipse!

In this art-related activity, learners make a coin rubbing—a process similar to what archeologists may do with ancient artifacts. This activity can be used in connection with a history or art lesson.

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this craft activity, learners create a string of cut-out moons and stars.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this activity (page 11 of the PDF), learners investigate how quickly water moves through various materials. They measure and compare the permeability of gravel, sand, and soil.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
