In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

In this activity (18th on the page), learners conduct an experiment to examine memory.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

In this math lesson, learners explore polynomial and rational function patterns.

In this math lesson, learners compare products to determine the best product.

Millions of organisms can live in and around a body of water.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this activity, learners add squares to paper dominoes to make polyominoes.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

In this math lesson, learners rotate through various centers while comparing and ordering objects according to length.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.
