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, learners explore how the power of the sun can be harnessed to heat and cool a building.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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

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 activity, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

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 activity, learners discover how solar energy can be used to heat water.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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, challenge learners to keep an ice cube from completely melting in 30 minutes. Learners engineer a box or wrap to prevent an ice cube from melting.

This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
