In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

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

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

Whether it's the genetic code, an ancient language, or patterns of light in a distant galaxy, scientists often have to play the role of decoder.

In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

In this activity, learners compare the ancient Egyptian system of measurement, which was based on body lengths, to the customary and metric systems used today.

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, learners explore how two cylinders that look the same may roll down a ramp at different rates.

This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

Learners investigate how the temperature of water affects its density.

Learners will determine their respiratory rate and explore the factors that affect breathing rate by filling out and using the Respiratory Chart provided in the lesson.

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.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.
