In this activity, learners explore how ordinary marshmallows expand when heated in a microwave.

In this activity, learners cook amino acids and sugar to explore the range of aromas released.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

Use this hands-on activity to demonstrate infrared and thermal radiation.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
