Top 101+ Amazing Environmental Science Project Ideas for High School

Amazing Environmental Science Project Ideas

Environmental science is an interesting subject that lets high school students learn about important stuff like pollution, climate change, green technology, and taking care of the planet. Doing projects is a fun way for teens to understand the world and how people impact it. 

In this blog, we made a list of over 100 ideas for hands-on projects about the environment that high schoolers can do alone or with friends. The projects we picked out range from easy experiments using basic materials at home to more complicated research topics. 

Each idea explains the experiment, how to do it, what you need, and what you might discover in simple language. Whether you want to test air or water, learn about renewable energy, look at recycling programs, or explore another environmental issue. 

You’ll find an awesome project that matches your skills and what you’re interested in. We aim to give high schoolers a list of meaningful environmental science projects that teach them about ecological challenges and solutions.
