In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this construction activity, students use a 2-liter bottle to build a fly trap.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this outdoor activity, learners find out the color of food that jays prefer and then try to change the birds' preference by altering the taste of the food with salt.
