In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners experiment with inertia by performing an easy and hands-on investigation with a playing card and a stack of coins. The activity includes an accompanying Mr.

In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract

Learners complete two simple experiments to prove the existence of air and air pressure which surround us.

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.
