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.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.

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 activity (23rd on the page), learners conduct an experiment to examine memory and learning.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

This is an activity about reaction times. Just how quickly must an NHL goalie respond to save a shot, and how does your reaction time compare?

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

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,

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

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

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.
