Standing in the Shadow of Earth
Source Institutions
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.

Why do Hurricanes go Counterclockwise in the Northern Hemisphere?
Source Institutions
In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.

What Causes Pressure?
Source Institutions
In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

Ocean Echolocation
Source Institutions
Use echolocation to find others and experience how whales’ senses have adapted to suit their environment. In pairs, learners are blindfolded and use containers filled with marbles to find each other.
Splitting White Light
Source Institutions
In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

Sunny Day Painting
Source Institutions
In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

Rocket Pinwheel
Source Institutions
This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.

Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

Soda Geyser
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

Solar Cell Simulation
Source Institutions
In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.

Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

Melts in Your Bag, Not in Your Hand
Source Institutions
In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

Spot the Sunspots
Source Institutions
In this activity, learners use binoculars (or a telescope) to identify and track sunspots. If using binoculars, learners need a pair that can be secured on a tripod.

Twirling Rope Frequency
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

The Shadow Knows II
Source Institutions
In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

Ancient Sun Observations
Source Institutions
In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
