Communicable diseases are caused by pathogens and can be transmitted from one person to another. You can become infected by a pathogen in several ways, including by drinking contaminated water, eating contaminated foods, receiving contaminated blood, and inhaling infectious aerosols (which are droplets from coughs or sneezes). In this lab you will simulate the transmission of a communicable disease.
The students will be able to visualize how water is stored in an aquifer. They will also see how groundwater becomes contaminated, and how these contaminants can end up in their drinking water. The main idea is to relate the above ground actions of people to the drinking water that is stored underground.
The following questions should be addressed and answered within the lesson: Where does our drinking water supply come from? (Groundwater or Surface Water) Why is it important to treat drinking water? What impurities or contaminants may be found in our drinking water? What are the effects of poor water quality on human health? How can our water be made safe to drink? What is the difference between rural and urban drinking water? What is the difference between Canadian drinking water guidelines and the regulations for Drinking Water in Europe and USA?
There are two major sources of water: Groundwater - found below the ground where it accumulated in between soil and rocks. The volume of water can range from small to very large similar to above ground creeks, rivers and lakes. Surface water - found on the Earth's surface in lakes, ponds, rivers, etc. Drinking water should be: Clear, Colourless, Odourless

The volume of water can range from small to very large similar to above ground creeks, rivers and lakes, found in bodies of water that resemble underground lakes called aquifers. Surface water - found on the Earth's surface in lakes, rivers, dugouts and reservoirs
