In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

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.

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 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.

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

In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
