In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil. Based on their observations, learners can conclude that both solids and...

In this hands-on activity (on page 2 of the PDF), learners experiment with lemon juice and paper to create a message that can only be revealed using chemistry. Using an oven as a heat source ...

In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs. Although...

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation. Learners compare the melting rate between chocolate left in the sunshine and chocolate...

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle. Use this activity to demonstrate the...

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. Learners design their own procedure,...

This is an activity about friction as well as kinetic and potential energy. Learners will be able differentiate between hard-boiled and raw eggs while they marvel at how one of the eggs seems to...

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving. The sugar will dissolve to a different extent in each...
