Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this physics activity, learners experiment with soap bubbles to see what variables affect their size. They explore how soap film and bubbles always seek the smallest surface area possible.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?

In this activity, learners discover what buoyancy is and determine the characteristics that make an object buoyant. Learners design, build, test, and evaluate boats made from a variety of materials.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.
