Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity on page 4 of the PDF (Get Cooking With Chemistry), learners investigate ingredients that combine to produce gas bubbles.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity, learners explore sublimation by conducting experiments with dry ice.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners explore how salt water freezes in comparison to fresh water.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

This activity was designed for blind learners, but all types of learners can explore the three states of matter by examining tactile models that illustrate the characteristics of particles in each sta

In this activity, learners make instant ice cream without using a freezer.
