Plastic Identification Lab

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....

In this recycling worksheet, students search for as many types of plastics categorized with the resin identification codes and fill in a chart for each plastic type. They identify the product name, the category the plastic is in, the...

Students are challenged to investigate the physical and chemical properties of plastics and use them to design a system that could be used to separate them. 1st year chemistry students use density for separation, students gathered...

Explore the unique characteristics of polymers. A complete activity begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

There is the same amount of water on earth now as there was when it was formed. The water from your faucet could contain molecules that dinosaurs drank! Young scientists build their own hydrologic cycle model and observe...

Young scientists play tag as they act out the food pyramid in the ocean ecosystem. Energy circles pass from the smaller prey to the predators and at the end of the activity, a data chart and analysis questions allow pupils to apply their...

Students explore the field of nanotechnology by examining magnetic field strength in ferrofluids. They use probes attached to a computer program to determine the relationship between magnetic field strength and magnetic field lines.

Students investigate plastic resins and their uses. In this plastics lesson plan, students describe major plastic resins and what they are used for, they compare and contrast the properties of plastic resins and they list products that...

Tenth graders participate in an arthropod scavenger hunt. In groups of two, they identify and collect two specimens of arthropods in the school area, and create a table of all the specimens and what class they belong to.
