The human population on Earth is now more than 7.5 billion, and growing quickly. With more and more of us living an energy-intensive, modern lifestyle, the environmental stresses from human activity continue to increase. Greenhouse gases leading to global warming and fertilizer runoff resulting in marine "dead zones" are just two examples of large-scale environmental impacts from human activity. Try one of our environmental engineering projects to see how science, engineering and technology can help us take good care of our environment while still enjoying the comforts of a modern lifestyle.

Science Fair Project Idea
Have you ever thought about being stranded on a desert island? How would you find water to drink? What would you need to survive? In this science fair project you'll discover how to turn the ocean into a source of freshwater by using the power of the Sun. Read more
Science Fair Project Idea
Have you ever seen news coverage or other pictures of an oil spill in the ocean and wondered how all of that oil could be cleaned up? Oil spills can devastate wildlife by covering them with oil, and they can damage our precious water resources by contaminating them with oil. Part of the problem of dealing with oil spills is that the oil can be challenging to clean up. In this science project, you will test the absorptivity of different materials (called sorbents) to discover which ones are best… Read more
