In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

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

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

In this activity, learners use their hands as tools for indirect measurement.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

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.

In this activity, learners observe tide pool animals in a touch tank to consider how they survive.

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

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.

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

In this water activity, learners discover ways to move water across the water table.

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

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

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.

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.

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

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.

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.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners model ancient lunar impacts using water balloons.
