Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

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 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 quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

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