Smarter Farming with Aerial Photo Analysis
Science Fair Project Idea
Scientific Method
Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.

Recycling Greywater: Can Plants Tolerate It?
Science Fair Project Idea
Scientific Method
One way to conserve water is to find safe ways to use it more than once. Here is a project to test whether greywater (water that has been used for washing or bathing) can be used for watering ornamental plants. Read more
Harmful or Helpful? The Effects of Hydrogen Peroxide on the Roots of Plant Cuttings & on Seed Germination
Science Fair Project Idea
Scientific Method
Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings. Read more
Attack of the Killer Cabbage Clones
Science Fair Project Idea
Scientific Method
Do you like to watch outdated science fiction and cheesy horror movies? Many fictional tales of cloned organisms have been created based upon the scientific method for cloning animals or plants. In the real world, the cloning of plants is a common method used in modern farming. How do you clone a plant? In this science project you will get to find out by making your own cabbage clones!

Top Crops: Finding Hidden Grasses and Beans in Processed Foods
Science Fair Project Idea
Scientific Method
It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more
Soil Color and Moisture
Science Fair Project Idea
Scientific Method
Have you ever taken a step onto what appeared to be dry ground, only to find yourself ankle-deep in mud? Yuck! When you walk through damp soil, it can be a very messy experience. How can you tell if soil is wet or dry before you step on it? In this science project, you will investigate whether the color of the soil can help you determine how dry or wet it is. Read more
Porosity and Particle Size
Science Fair Project Idea
Scientific Method
Often, when we think of something that is solid we think about rocks. But in reality, rocks have tiny holes of air inside them. This is called porosity. In this science project you can find out what it means to be "solid as a rock!" Read more
Is the Soup Ready? Measure How Much Water is Absorbed by Dried Beans
Science Fair Project Idea
Scientific Method
Dried beans are a major ingredient in dishes served all over the world. In their dried form, they can be stored for years and then "brought back to life" by soaking them in water. In this cooking and food science fair project, you will measure just how much water is absorbed by beans when they rehydrate (soak up water). Can such a little bean really hold that much water? Read more
Earthworm Castings — The Ideal Proportion in Soil for Young Garden Plants
Science Fair Project Idea
Scientific Method
Everybody knows that worms are good for the soil, but not everybody knows why. Here's a project that investigates just one of the ways earthworms improve the earth. Would earthworm castings (or earthworm manure) help your plants prosper and flourish? If so, how much should you use? Read more
Get Rid of Those Leftovers: How Much Organic Waste Can Composting Worms Eat?
Science Fair Project Idea
Scientific Method
What happens to the food leftovers in your home? Do they go in the trash? Down the garbage disposal? Or get gobbled up by the family dog? Food leftovers are a type of organic waste, a waste that comes from a plant or animal. Organic waste—like table scraps, agricultural waste, and human and animal waste—is biodegradable. This means, it can be chemically broken down by bacteria, fungi, or other living organisms into very small parts. Figure 1. This… Read more
