Chemistry Hall of Fame: Polyethylene a Plastic of Many Uses

After reading about polymer materials, engineer trainees examine how plastics have been integrated into everyday products. In groups, they compile a list of products made entirely without plastics and then, as a closing activity, try to...

Imagine having to give up cell phones, computers, and TV? What would be lost? What gained? An examination of the Drokpa, a nomadic people who live in the grasslands of Tibet, provides class members an opportunity to consider how access...

It's not often that you come across a clever laboratory activity that is both imaginative and comprehensive! Using M&M's and Reese's peanut butter candies to represent two different clam species, young biologists test for "relative...

First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling....

Explanations for six different physics lab activities and five suggested assessments are contained in this resource by the National Science Teachers Association. Any combination can be used to open learners' eyes to rotational motion....

Inspire environmentally conscious young minds with an exceptional video, which traces the life cycles of three different plastic bottles after they are thrown away and move through the earth with different journeys through a...

Viewers consider shrinking down to the size of the nanoscale. With fairy-tale-like animation and narration, they imagine what they could see if they were 1,000 times smaller than a red blood cell! Use this clip in any class where you...

Excellent examples and clear diagrams in this PowerPoint will help you explain the genetics of alleles and the combinations of hybrid crosses. A high school class would appreciate having this student copy of the PowerPoint as the images...

Have you heard of the Fosbury Flop? It was invented by a college high jumper in and has become the standard technique for high jumpers world wide. Learn the physics of this move and why it is more effective for clearing the bar than the...

The mind-bending concept of space-time is further discussed by two cartoon scientists in this second of three animated films. Assign each part and the accompanying Think questions as homework or as an enrichment when working on motion...
