In this water activity, learners explore how water drops behave on different surfaces.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

In this quick activity (page 1 of the PDF under SciGirls Activity: California Fish), learners will build a simple Cartesian Diver in an empty 2-liter bottle.

In this activity, learners discover that sand is the major ingredient in glass.

In this activity, learners use Teflon (PTFE) tape to write secret messages.

In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

Make your own mummy! Using a combination of salts, transform an apple into a mummy and discover how the Ancient Egyptians used drying as one step in the mummification process.

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.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

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

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

In this activity about global climate change, learners will conduct an experiment and collect data to compare the amount of carbon dioxide (CO2) in four different sources of gases.
