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

In this activity, learners develop an understanding of cylinders and volume as they compare two sizes of popcorn buckets.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

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.

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners investigate how different materials repel or absorb water. Learners use spray bottles to explore how everyday items like sponges, cardboard, feathers, etc.

Learners follow a three-step process to start their own rock collection.

In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

In this online activity, learners adjust mountain snowfall and temperature to see how glaciers grow and shrink. They will use scientific tools to measure thickness, velocity and glacial budget.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.
