Environmental Science Science Projects (52 results)

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. With our list of environmental science fair project you can explore and understand important topics like air quality, water quality, the effects of climate change, and many others so that you can make informed decisions about caring for our planet.

Bug Vacuums: Sucking up Biodiversity
Science Fair Project Idea
Have you ever wondered what a wildlife biologist does? Ronnie and Denise from DragonflyTV found out firsthand when they worked with a local wildlife biologist to take a survey of the fish populations in their local lake. They wanted to determine what the biodiversity (number of different species in a habitat) was like so that they could find out how healthy the lake habitat was. In this science fair project you can take on the role of a wildlife biologist by examining the biodiversity of… Read more

Air Pollution
Science Fair Project Idea
Smog days are often posted in your local newspaper. Check how many smog days your city has had in the last year. How does it compare to to other years? You can also take pictures of your city landscape on high and low smog days. How do the pictures compare? How does smog in the atmosphere affect visibility? What is smog made of? You can use tongue depressors smeared with Vaseline to check for smog particles in different areas; just stick in the ground and look at them a few days later. … Read more

Are There Dangerous Levels of Lead in Local Soil?
Science Fair Project Idea
The element lead is a neurotoxin that is particularly dangerous to young children. Among other uses, lead compounds were common paint additives until being phased out for safer titanium-based additives beginning in the 1960's. Lead compounds were also added to gasoline to prevent engine knocking, until being phased out beginning in the 1970's. Although paint and gasoline sold today no longer contain lead, soil can have contamination from older sources of lead, such as paint from old… Read more
