In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.

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

In this chemistry challenge, learners discover that many chemical reactions involve heat loss or gain.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

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

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

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 explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

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

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.
