Students will then be able to understand and appreciate some of the grave concerns and issues and the need for environmental control. 6. And students will want to appreciate their environment and this great planet earth upon which we live more. Materials Needed: 1. visual aids - models of 2. soil 3. household chemicals sun clay hair spray ozone layers water nail polish remover earth rocks bleach vehicles wood chips perm poster boards plastic cups baking soda noise device plastic motor oil Strategy: a. Experiment will start with myself wearing many protective devices. I will be wearing a hard hat, safety goggles, ears plugs, gloves, boots, face mask, etc. Students will undoubtedly want an explanation. We then will review and discuss what we've learned from our previous lessons. Then students will begin to answer their own curiosity. They will tell me why I may be wearing different devices. They will want to identify each device probably with some form of pollution. Now they will feel familiar and confident. b. We will examine the models of the sun, ozone layers, and the earth. We will discuss how the sun helps us and how it could possibly harm us with its powerful ray. Students will learn that the ozone layers are like sunglasses for the earth, a very valuable pair that cannot be replaced. c. Students will be encouraged to examine different factors that are unfortunately contributing to acid rain. Ex. vehicles, factories, household items, etc. d. We will spray some of the chemicals on the model of the ozone layers which will be made of tissue paper to signify its fragileness. Students can discuss in brief the danger involved with the damaged layers. Ex. skin cancer, eyes. e. In a transparent plastic cup each group will build several layers of the earth from sand, soil, clay and rocks. They will each have four cups of water. Now they will do several tests with the water. Each is to be mixed with a household chemical. Using pH strips They will test the water with the chemicals and again after they've poured it through the earth's layers. These tests will help students determine how pollution is affecting our water supply and the soil that grows our food. * They will understand our survival is at risk. * Enforcement and Enrichment a. English - write letters to Environmental Protection, aldermen, senators, representatives, and the president of the United State expressing appreciation or concerns b.
