This is a Power Point presentation on exploring materials. It includes information on polymers and monomers, plastics, composites, synthetic polymers, alloys, steels, ceramics, glass, optical fiber, nuclear reactions, radioactivity, alpha, beta particles, gamma radiation, half-life, radioactive dating, tracers, etc.
This Power Point is 11 slides and comes from Prentice Hall Science Explorer Grade 8 Chapter 18. However, it could be adapted to cover this topic from any Science Textbook Series.
***This item is also included in the Science CD that I sell separately which includes all of my Science digital products (power points, printables, etc.)
