Do a Nature Survey Science Projects (13 results)

Survey the natural world to discover the answer to a science question. Take measurements of stars or the moon, take samples of soil or water properties at different sites, or find patterns in data about the natural world by accessing free online databases.

Water Quality
Science Fair Project Idea
Scientific Method
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. … Read more
How Does Soil Affect the pH of Water?
Science Fair Project Idea
Scientific Method
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. Read more
Are There Bugs Under Your Feet?
Science Fair Project Idea
Scientific Method
Look out! When you walk on the grass, you are squishing millions of micro-invertebrates! Just kidding, these animals are too small to squish. Learn how to catch them by making a Berlese funnel in this fun project that will teach you about soil. Read more
How Salty is the Sea?
Science Fair Project Idea
Scientific Method
Have you ever been swimming at the beach and gotten some water in your mouth by mistake? Then you know that the ocean is very salty. But what about other bodies of water? How much salt do they have compared to the ocean? Read more
Study the Effect of Fertilizers on Algal Growth
Science Fair Project Idea
Scientific Method
You might not know it, but a lake without algae would be a very dull place. If there were no algae, there would be no small animals feeding on the algae, and there wouldn't be any fish eating the small animals that eat the algae. You might conclude that since some algae is good, more algae is even better, but algae growth has a down side. If there is too much algae, they can deplete the oxygen in the water, killing off other species in the water. What is one culprit that leads to algal growth?… Read more
Using a Digital Camera to Measure Skyglow
Science Fair Project Idea
Scientific Method
This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations. Read more
How Does Soil Change with Depth?
Science Fair Project Idea
Scientific Method
What covers less than 10% of the Earth's surface, yet is a vital natural resource for terrestrial life? What filters ground water and supports most of our food production, not to mention the production of building materials and paper? The answer, often overlooked, is: soil. With this project you can get all the dirt on soil formation, soil horizons, and the composition of different soils. Read more
Where Did All the Stars Go?
Science Fair Project Idea
Scientific Method
One of my favorite things to do when I was a kid was to go outside and look at the stars. As an adult, I moved to a major city and the stars seemed to vanish from the sky. Where did they go? Read more
Measuring Soil Erosion
Science Fair Project Idea
Scientific Method
When you think of environmental challenges facing the world, the first things that come to mind might be global warming, or loss of biodiversity, since these are often in the newspapers. A serious problem that you may not have heard about is soil erosion. Why is soil so important? What is the danger of erosion? How can we measure soil erosion? What can be done to prevent it? Check out this project and you can start finding answers. Read more
Chemical Analysis of Rainwater
Science Fair Project Idea
Scientific Method
Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize the scientific area that most interests you. Read more
