In this activity, learners explore the different heating properties of soil and water.

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.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this activity (1st on the page), learners explore circadian rhythms by keeping track of their body temperature.

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!

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

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

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

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 activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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.
