In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.

In this fun chemistry activity (page 3 of the pdf), learners use cabbage juice to determine the pH of several substances.

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

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 physics activity (page 8 of the PDF), learners will make their very own working compass.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

Learners build simple catapults and use them to launch cotton balls.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

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 activity, learners create and understand surface currents. Learners create example surface currents and discover how landmasses affect the current.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.
