Science Fair Project Idea
As you move up or down in altitude or elevation, the temperature and pressure will change. This is particularly striking if you live near a mountain range. During the summer, at low altitudes you may have temperatures in the 80's or 90's and still be able to see snow on mountain peaks at high altitude. You can test the effect of altitude by comparing temperature data from weather stations at high and low altitudes. You can test the effect of elevation by making your own weather balloon and… Read more

The ozone layer is important for blocking most of the harmful radiation that comes from the sun. You can find maps of the ozone layer and compare different regions of the globe for ozone coverage. Where are the problem areas? Is there a difference in ozone coverage between different hemispheres? Between populated and un-populated areas? In atmospheric regions over land masses or over bodies of water? Some scientists think that aerosols in the air are breaking down the ozone layer. You can do… Read more

Survey your area to find out which species of plants and animals live there. You might be surprised to find out that something you grew up thinking was very common, is actually quite unique! For example, if you live in the great plains, then you may think that prairie dogs are a nuisance or a pest. Actually, some species of prairie dogs are only found here, and have a very important role for short and tall grass prairie ecosystems. The prairie dogs are an important part of the food-chain, and… Read more

Our forests are a very important natural resource that need to be managed wisely. We use wood products for many different purposes: building materials, paper, cardboard, furniture, fuel, etc. How can we use wood products in a sustainable manner? You can do experiments that examine the growth time of different tree species to see which are good candidates for tree farming. Which types of lumber are most sustainable? You can also compare the effects of clear cutting vs. thinning a forested… Read more

Visit your local landfill to collect dumping statistics by watching the types of trash people bring to the dump. Identify problem areas and types of waste that are commonly brought to the dump. Propose new uses for common landfill problems like tires, construction materials, plastics, appliances, and computer parts. Measure packaging materials of some common products. Invent ways to reduce the amount of packaging and increase the use of recyclable materials like popcorn or corn-based packing… Read more

thumbnail On a rainy day, do you ever wonder what the weather is like on the other side of the planet? Different regions around the globe can have very different seasonal weather patterns. In this experiment, you can test if these seasonal variations are related to which hemisphere each region is located in. Read more

Some plants use a lot of water, and some are very drought-tolerant. Drought-tolerant grasses are good for water conservation because they require less water to grow and stay green. How much less water do they need? Which types of grass are drought-tolerant? You can buy different types or brands of grass seed at your nursery that claim to be drought-tolerant. Grow them in a container and then starve for water after they are established. Which brands die out first? You can conduct a similar… Read more

The sustainability of our ocean fisheries is a topic of concern for many, including environmentalists and fishermen who make their living on the bounty of the sea. It is important to use sustainable fishing practices so that our fisheries are not over-fished leading to a decline in productivity. Some states require fish markets to post information about their fish so that consumers can make informed decisions about which fish to buy. They post the type of fish (e.g., Coho Salmon), the source of… Read more

Silt is a fine sediment that collects on the bottoms of rivers, streams and lakes. The natural process of the decay of organisms into the water can lead to the production of silt at the bottom of a lake. Silt can be a rich source of nutrients for fish and bottom dwellers like crayfish. However, it can also be introduced by unnatural processes. One problem for rivers, lakes and streams is the buildup of excess fine sediment introduced by industry. Because it often contains harmful chemicals it… Read more

How much water do you use? Conserving water can do more than save your parents' money, it can also save freshwater ecosystems, wetlands, and watersheds. Some companies are trying to help fix the problem by making low flow faucets and showerheads. How well do they work? How much water can you save? Go to the hardware store to buy a few of the water saving products. Compare the amount of water that you run over a period of time to determine how much water you can save. Which water saving… Read more
