Determine the dew point temperature for your classroom through a hands-on experiment. Use humidity and temperature probes to investigate the temperature at which it would rain in your classroom! Learn about water density and the conditions necessary to produce fog or rain.

The forests of North America have seen plenty of change in a pretty short period of time, at least geologically speaking. Up until about 18,000 years ago, the Laurentide Ice Sheet covered Canada and much of the eastern United States. When temperatures climbed and the ice sheet retreated, forests gradually reemerged. But how? Did pockets of trees find refuge in sheltered areas during the Ice Age? Or were all tree species pushed to the southern tier of the United States, only to spread north again after the ice disappeared? Scientists still debate the topic, but one thing is clear: today’s forests in the eastern United States bear little resemblance to post-glacial forests. Starting with European colonial settlers and marching through four centuries of development, drought, and fire, the tree cover of North America became fragmented.

Learn about concentrations of solutions. If you brew tea or coffee for too long, it gets really strong, bitter, and dark. But if you add water, you can lessen its strength. So, when we talk about how strong our coffee is, we are really talking about CONCENTRATION. Like stirring a teaspoon of sugar into a cup of tea, solids can have a concentration in a liquid, but first, they need to be able to dissolve into a solution (solubility). But, is there a limit to how much of a solid the solution can take in? Through some sweet treats, you can eat, let's explore the scientific concepts of concentration, solubility, and supersaturated solutions. I promise you it's going to ROCK! Developed for students in grades 6-10.
