Science Fair Project Idea

Scientific Method

If you're interested in arts and crafts, you might like this project. It uses several alternative, renewable sources of fiber to make paper, and compares the resulting papers for strength and writing quality. Read more

Can Mulch Reduce Garden Water Requirements?

Science Fair Project Idea

Scientific Method

Divide a part of your garden into two equal plots, with each plot receiving equal amounts of sun. Cover one plot with two inches of organic mulch, such as compost or ground bark. Leave the other plot uncovered. Use the same amount of water for each plot for two or three weeks. At the beginning of the experiment, and at one-week intervals, dig down and check the soil in each plot for moisture content. Which plot holds water better? Which plot shows better plant growth?

Solar-Powered Salt Removal

Science Fair Project Idea

Scientific Method

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

Cleaning Up Oil Spills

Science Fair Project Idea

Scientific Method

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

Do Your Storm Drains Keep the Ocean Trash Free?

Science Fair Project Idea

Scientific Method

Did you know that there is plastic in the ocean? It probably isn't too hard to imagine that some of the plastic that litters roadways, sidewalks, and parks finds its way into the ocean. So, how much do you think is in there? Hundreds of pounds of plastic? How about thousands of pounds? No one knows for sure, but estimates, based on scientific surveys, suggest the amount is in the range of millions of pounds of plastic! Of course, the ocean is big, over 300 million square kilometers, so… Read more

Make an Automatic Evaporative Cooling System

Science Fair Project Idea

Engineering Design Process

You probably know that sweat helps cool your skin on a hot day because of evaporation. But do you think you can use evaporation to cool a building? Evaporative cooling systems could provide a more environmentally-friendly alternative to traditional air conditioning. In this engineering project you will build and try to optimize your own model evaporative cooling system. Read more

Rooftop Gardens: Are They a Cool Idea?

Science Fair Project Idea

Scientific Method

Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Do Plants Promote Pesticide Breakdown?

Science Fair Project Idea

Scientific Method

When pesticides are applied to protect crops, run-off of potentially harmful pesticides is a major problem. Can water plants such as hardstem bulrush, common cattail, parrotfeather and smooth scouring rush promote pesticide breakdown? If so, diversion of irrigation run-off into plant-filled ponds could help reduce pesticide pollution. Mix malathion at 12.5% of the recommended application strength (to simulate dilution by rain or irrigation water). Use 5-gallon buckets for testing various… Read more

Fish + Food = Science of Aquaponics

Science Fair Project Idea

Scientific Method

How are we going to feed the more than 9 billion people that will live on Earth by 2050? This is a major question for farmers, ranchers, and food scientists around the globe. It's a big problem, considering that from 2017 to 2050 we will be adding 1.5 billion people and need 20% more food. Linked to this problem of producing enough food is having enough land, water, and other natural resources to make that happen. The final solution will surely be made up of many different approaches working… Read more

Riprap: It's Not Hip Hop But Erosion Stop

Science Fair Project Idea

Scientific Method

Have you ever been to the Grand Canyon and seen what water can do over millions of years? When you turn on the faucet, do you see water come out, or mud? In this experiment you'll find out how engineers help prevent erosion, which keeps dirt out of our water. Read more
