As humans we are part of the environment. With over 7.5 billion of us on Earth, our combined actions also have a big impact on the environment. As long as we are aware of the impact, we can do things as individuals, and working together as groups, to lessen the detrimental impact of billions of people. Explore important topics like air quality, water quality, the effects of climate change, and many others to make informed decisions about caring for our planet.

Try the annual Engineering Challenge from Science Buddies! Open to all students worldwide, a new challenge and prizes are announced every January. Explore the current challenge as well as ones from past years!
Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants!

In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. Enter your score in the 2024 Science Buddies Engineering Challenge for a chance to win prizes! Teachers, lesson plan versions of this challenge are also available.
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. …

Does your home have any pet doors or gates for dogs, cats, or other animals? Some automatic pet doors can be set up to allow only certain animals through. These doors can help you control which pets are able to go outside alone or which ones have access to specific food, litter boxes, or toys. But why buy such a door when you can make one? In this project you will build your own automatic pet door that works with a magnetic collar tag. Exactly how you use it is up to you!
Growing crops takes a huge amount of water. That same water is also needed for drinking, bathing, and other industries. In dry climates or lands experiencing drought, there is a big push to conserve (save) water as much as possible. In this project you will experiment with creating environmentally friendly jelly-like materials called hydrogels and see if they can help soil retain water thus reducing the amount of water needed to grow crops.
What does the phrase, "Like a breath of fresh air," mean to you? This common phrase can have different meanings: calming, relaxing, invigorating, energizing or CLEAN! After all, you never hear anyone say, "Like a breath of dirty air," do you? Find out how clean the air is in this simple experiment.
Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out.
What looks pretty, stops flooding, and helps fight pollution? A rain garden! Find out how by building and testing your own miniature rain garden in a plastic bottle.
Chemicals from Earth's atmosphere are making their way down to the planet! Not in spaceships, but in rain. The acid rain can infiltrate ground water, lakes, and streams. How does acid rain affect aquatic ecosystems?
Has the temperature in your house felt hotter or colder recently? This could be due to the greenhouse effect. The greenhouse effect states that gases in the atmosphere, such as CO2, might increase the surface temperature of Earth. In this science fair project, you will build a small model of Earth and use it to see how the temperature varies, compared to outside of the model. If you select this science fair project, you will be a part of the effort that is working to figure out what role…
There is strong interest in "going green," including using products that cause less environmental damage when they are disposed of. In this environmental sciences project, you will compare the toxicity of "green" and conventional liquid detergents using worms as test organisms.
Imagine a wonderful summer day at the beach. You play in the sand, swim in the ocean—and, of course, put a lot of sunscreen on. The sunscreen protects your skin from harmful ultraviolet (UV) radiation. Special ingredients absorb or reflect the UV rays so they do not harm your skin. Different types of sunscreen have different types of ingredients, and some of them can be harmful to the environment—especially if they get into the ocean. In this science project you will put your…
