Do you filter your tap water before drinking? Many commercials claim these filters make your drinking water cleaner and safer. But what, exactly, are these filters doing and is the water really cleaner afterwards? The cleaning power comes from their filling material, called activated carbon. It exists in all kind of forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this activity you will investigate whether larger or…

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. …

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?

Living in the industrialized world, like the United States, we are fortunate because we don't have to worry about the quality of our drinking water. Your community has the means to clean and provide water to you. But in many parts of the world, people don't have this luxury. Whether it is due to war or poverty, the lack of clean water leads to many health and social problems. In this environmental engineering science project, you will learn about different methods to filter out impurities in…

Have you ever thought about how fortunate you are to have safe and clean water coming out of your faucet? Many people in undeveloped nations don't have this luxury. But does that mean they can't have clean water at all? Is there an inexpensive way they could use to make their own clean water? In this microbiology science fair project, you will investigate whether or not sunlight can disinfect contaminated water.

Your drinking water probably started out brown and muddy. Are you surprised? Maybe you were picturing it flowing from a clean mountain spring instead? All over the world, including in 68% of American homes, people get their drinking water from rivers, lakes, and other surface waters. This water is filled with dirt, debris, and other contaminants as it travels hundreds of miles. So, how does your drinking water go from brown and muddy to crystal clear? Often, flocculants—substances that…

Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams,
reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find
and a precious resource. In this environmental engineering science project, you will investigate one way
that people living in arid regions can collect water inexpensively: dew traps.

Lead is a very hazardous element. Even very small amounts can cause health problems, especially in babies and young children. One way to determine if a household item, such as a toy or a piece of jewelry, contains lead is to soak the item in a solution, and then test the solution for lead that might have leached out of the item. The goal of this chemistry science fair project is to determine how varying the pH of the test solution affects its ability to dissolve lead, which is a critical step…

We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or
the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many?
Because we humans understand how important rain is to our well-being. Rainfall, as part of the
water cycle, brings water back to Earth that had previously evaporated or transpired
from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,…
