In this lesson, a ready-to-teach cooperative reading activity, students learn about the effects of plastics in our environment, specifically that certain petrochemicals act as artificial estrogens and impact hormonal activities. Much of the content in this lesson was synthesized from recent medical research about the impact of xenoestrogens and…

A method for printing designs on plastic containers is presented. (CK)

A study demonstrates the potential application of conducting polymers to convert electrical energy into mechanical energy at low voltage or current. The performance of the device is explained using electrochemistry and solid-state chemistry.

Secondary vocational-technical education programs in Mississippi are faced with many challenges resulting from sweeping educational reforms at the national and state levels. Schools and teachers are increasingly being held accountable for providing true learning activities to every student in the classroom. This accountability is measured through…

The study describes the various thermal equilibrium conditions, which should be taken care for while designing or selecting the plastic and glass microscale containers for physical chemistry experiments. The results show that the thermal equilibrium completely depends on the material of the container for the same volume and thickness.

Plastics can be combined with several of the more traditional material areas of industrial arts instruction to introduce a more truly industrialized approach. (MS)

Describes how to make wooden molds and then form plastic laminates using the molds. (GB)

Describes the technology of the recycling process for high density polyethylene plastics; illustrates a way for technology teachers to demonstrate the process. (SK)

Various properties of polymers can be demonstrated using these simple tricks and recipes that were previously described in the 2002/3 IOP Schools and Colleges Lecture.

The construction of combined plastic membrane electrode for hydralazinium cation from a disposed glass electrode is described. A variety of electrodes could be prepared by students using other types of polymers, plasticizers, or exchangers which could also help to study effects of pH and temperature, or environmental investigations.
