How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? What factors affect how effectively saltwater is turned into fresh water? Read more

This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. Read more

It is important to ensure that we all have good clean water to drink that is not contaminated by heavy metals or chemicals. One common pollutant in a water supply is lead in old pipes or paints that can leach into the water and cause lead poisoning. There are different kits available for testing the presence of lead and other contaminants in water. Test your water supply, and also the water in some local ponds, lakes or streams. The same contaminants that can harm you can also harm wildlife. … Read more
