In this lesson, we discuss the distribution of electrons in a carbon atom, introduce the students to examples of plastic materials made from organic compounds, explore environmentally safe materials that can mimic the same properties of plastic and explore the effects of bacteria and fungi on plastic materials. It is important that students are familiar with the periodic table of elements. The video is 25 minutes long with approximately 20 minutes of activities. Students should be prepared with pen and paper as they will be asked to draw electron distribution and ethane/propane.
