It's the Slime Time

Students investigate the physical properties of a rather peculiar substance commonly known as slime. They devise and carryout a procedure for testing the effect of varying concentrations of either the poly(vinyl alcohol) or the borax...

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

Bacteria outnumber all other living organisms found on Earth. Explore the evolutionary precursor to multicellular organisms, unicellular organisms with a video that delves into the world of bacteria, protists, and archaea and compares...

Students combine the skills and concepts that they have developed to ask a simple question which can be answered on a Petri plate. They ask questions and design experiments for verification through collaboration with their classmates.

Students explore change in physical properties of polymer as result of cross-linking. Students consider result of adding more cross-linking agents to polymer, view model of cross-linking, and complete monomer identification.

Students investigate polymers by completing 3 experiments. In this polymer lesson plan, students mix plastic with acetone, they create polyurethane foam, they make slime and build a polymer model once their polyurethane foam is set. ...

Young scholars study the concepts of polymerization and the function of crosslinkage.  In this polymer lesson students complete a lab activity and write down their observations.
