Project Idea
The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to become more acidic. What impact does that have on the marine life? In this ocean science fair project, you will demonstrate ocean acidification and investigate the effect on the shells of marine life. Read more

Project Idea
thumbnail 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

Project Idea
Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes… Read more

Time Required Long (2-4 weeks)
Prerequisites This science fair project must be performed in a well-ventilated area; a fume hood is recommended. You must also have a teacher who can help you order the necessary chemicals.
Material Availability Specialty items are required. You will need methanol, and either potassium hydroxide or sodium hydroxide. See the Guide to Purchasing Chemicals for more information.
Cost High ($100 - $150)
Safety Minor injury is possible. You must wear safety goggles and gloves when dealing with chemicals. Do not breathe in fumes from the chemicals. Read and follow the suggestions in the Chemistry Safety Guide.
Project Idea
thumbnail If you leave an ice cube out on the kitchen counter and come back to check on it in awhile, what do you find? A puddle! The same thing happens to ice in nature—if the temperature gets warm enough, it melts. In this ocean science project, you will find out what happens to sea levels if the ice at the North Pole melts, or if the ice at the South Pole melts. It is an important question for the millions of people who enjoy living along the coasts of the world. Read more

Project Idea
thumbnail What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

Project Idea
thumbnail The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. Read more

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

thumbnail 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

Trees grow more during the early spring than they do the rest of the year. Because of this period of dormancy, or lack of growth, each year of growth is marked by a line called a tree ring. You can count the number of rings in the cross section of a tree trunk to show how old the tree is. You can also count the number of rings in a stem to see the age of a stem or branch. One way to measure the rate of growth of a tree is to count the number of rings per inch. Trees with high numbers of… Read more
