This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors. The PDF contains step...

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules! Learners measure 18 grams (or 18 ml) of water which is equivalent to 1 mole of water and...

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick. Learners...

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix. In chemistry, this mixture is...

In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms. Information about...

In this activity, learners investigate convection by using food coloring and water of different temperatures. Through this experiment, learners discover the effect of gravity, density, and...

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of...

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil. Then learners use the device to test if a solution, a series of solutions, and a solution...
