Chemical Resistance and Synthetic Polymers

Students examine elastomeric polymers in a lab activity in which they design a bungee cord. Students must determine the tensile strength, percent elongation, and plot stress versus strain graphs for their experiments on rubber bands...

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

Chemistry classes pretend to be consultants to a grocery story trying to decide what polymer to use for therir new non-paper bags. They prepare tensile bars and use them to test plastic film samples for strength and stretchability. Both...

This in-depth organic chemistry lab walks learners through an investigation of the effect of initiator concentration on the resulting molecular weight of polystyrene. It is important that you use this lesson with experienced chemistry...

In this endocrine system worksheet, students match the correct gland found in the endocrine system to its hormone and target cell(s). They also describe the actions of each gland and hormone combined together.

The use of biodegradable polymers revolutionized many branches of medicine. The video explains what synthetic polymers are and why they are important. Through numerous examples of real-life applications, scholars learn their importance...

In this physics worksheet, students design an electric power supply and answer 5 short answer questions about it. They explain the functions of the different circuit components.

Young scholars demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
