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

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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.

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, 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.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

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.

Este Web site contiene links a 12 calendarios (12 meses). Cada mes contiene actividades sobre matemáticas.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

Learners build a lever and use it to lift a load. With the load on one end of the ruler, learners add coins to the effort cup at the other end until the load is lifted.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.
