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.

Remove Microplastics from Water with Bioremediation
Science Fair Project Idea
Scientific Method
Have you ever walked by an ocean, lake, or river and seen plastic trash? Have you ever wondered how microplastics might be impacting the creatures living in these places? In this science project, you will investigate how yeast can be used in bioremediation to remove microplastics from contaminated water. Read more
Removing Microplastics from Water with Ferrofluids
Science Fair Project Idea
Scientific Method
Have you ever walked next to your favorite ocean, lake, or creek and seen plastic waste everywhere? Have you ever thought about how much plastic breaks down into microplastics and pollutes waterways? Scientists are coming up with new ways to remove these microplastics from our waterways, and now you can test them out for yourself at home.  Read more
Can Plants Stop Soil Erosion?
Science Fair Project Idea
Scientific Method
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! Read more
Wildfire Simulator
Science Fair Project Idea
Scientific Method
Wildfires can devastate communities, destroying homes and creating smoke that can affect air quality over huge areas. A wildfire could start from a natural cause like a lightning strike, or humans being careless with cigarette butts or campfires. What if you could predict how a wildfire will spread to help give people an advanced warning to get out of harm's way? Can forest management techniques like controlled burns—intentionally setting smaller, more controlled fires—help reduce… Read more
Fight Flooding and Pollution with...a Garden?!
Science Fair Project Idea
Scientific Method
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. Read more
The Role of Interdependence for Pollination and Seed Dispersal

4 reviews
Pollination and seed dispersal are both crucial processes in a plant's reproduction cycle. These processes are helped along by many factors, including different animals. For instance, some animals disperse the plant seeds, while others transfer pollen from one flower to another. In this lesson plan, students will investigate the interdependence between plants and animals for pollination and seed dispersal by creating interdependence webs out of yarn. Based on their created interdependence webs,… Read more
NGSS Performance Expectations:
  • 2-LS2-2. Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.
Harvesting Fresh Water With a Fog Catcher
Science Fair Project Idea
Scientific Method
Did you know that about 1 in 10 people worldwide do not have access to clean water? Collectively, girls and women worldwide spend an average of 200 million hours every day collecting the water they need from rivers, water holes, or lakes. What if there was a way to capture water from another source—like the air? In areas where there is a lot of fog, a device called a fog catcher makes this possible. Fog catchers use fine meshes to capture and collect water droplets from the foggy air.… Read more
Investigate the Greenhouse Effect
Science Fair Project Idea
Scientific Method
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… Read more
Acid Rain and Aquatic Life
Science Fair Project Idea
Scientific Method
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? Read more
Air Particles and Air Quality
Science Fair Project Idea
Scientific Method
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. Read more
