In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? What’s the most common? the least common?

In this activity, learners keep track of how much paper the group uses in a week. Build awareness of paper waste, while strengthening measurement and estimation skills.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

This activity puts a mathematical twist on the familiar “guessing jar.” No guesses allowed, estimates only.

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

This activity teaches combustion as the interaction of a fuel source and oxygen.

In this activity, learners will collect and analyze data to learn about the people around them. How many letters in everyone’s first name? What’s the most common number of letters?

In this chemistry activity, learners use common chemicals and metals to examine reactions that produce gaseous substances.
