In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In this activity, learners cut a shape into two equal sized pieces and use their knowledge of geometry and space to prove that the two parts are equal.

In the kitchen, learners can perform their own density investigation.

In this math activity, learners play a game in which every roll can earn you counters, but if you roll the wrong number (6), you have to put everything back.

In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

This activity introduces learners to Native Americans as people who depended upon nature in the past and continue to emphasize the importance of nature in the present.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this activity about gravity (page 6 of the PDF), learners will come to understand how all objects will fall at the same rate, but that air will slow things down.

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

In this Cyberchase activity, learners use math to explore how parts of the body are proportional.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
