In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
