Young scholars hang 200 sheets of paper, each with 5000 X's, around the classroom.When completed, this gives them a concrete example of 1,000,000 which is useful in getting a feel for the lengths of time involved in evolution.

Welcome to the companion Web site to the NOVA program "Einstein Revealed," originally broadcast in October, 1996. This two-hour special presents a penetrating profile of Albert Einstein, who contributed more than any other scientist to...

Students work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the lesson.

Students investigate how complex functions arise in biological systems through the creation of several paper structures to accomplish various tasks such as remaining suspended in air for the longest time, making the loudest noise and...

Students generate a radioactive decay table for an imaginary element, use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

Students design a craft that safely floats vegetables across a classroom. The teacher provides some materials, but the child may as well. As the experiment is created, they have to fill out worksheets to keep the actiivity organized....

Students engage in a lesson that is concerned with the water cycle and different states of matter. They conduct research using a variety of resources in preparation for taking a quiz. Then students take the quiz in correlation to having...
