1. What are the chemical compounds that react with water to produce acid rain? Write out the chemical reactions. 2. What produces sulfur dioxide emissions? 3. What produces nitrogen oxides emissions? 4. How does acid rain damage the environment?
Students will determine the pH of different solutions using indicator paper and a colour chart. Students will be able to relate pH value to whether a solution is acidic or basic. Students will examine how our drinking water and lake water is affected by its pH.
pH Scale - Draw your own pH scale by using the pH values obtained from the samples. Ensure that you label the pH values, the samples, and the acidic and basic sections of the pH scale.
1. Name and describe the two major sources of drinking water. 2. Name four contaminants that may be found in drinking water. 3. How many sources of contamination can you list? 4. List and describe the effects of contaminants in drinking water.
1. Name and describe the two major sources of drinking water. 1. Surface water: found on Earth's surface in lakes, rivers, dugouts and reservoirs 2. Groundwater: found in underground lakes called aquifers
