Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this math lesson, learners explore polynomial and rational function patterns.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this activity, learners explore density and buoyancy as they design and construct rafts.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.
