Compost Creativity: Try Various Methods and Test Soil Fertility
Add Favorite
Science Fair Project Idea
Scientific Method
Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does a 'hot' compost pile compare to a 'cold' compost pile, or how does traditional composting compare to worm composting, or vermiculture? Figure 1. Different composting methods yield different soils. In this picture, the soil on… Read more
Cryopreservation: Freezing Plant Tissues
Add Favorite
Science Fair Project Idea
Scientific Method
Cryopreservation—storing seeds in ultra-cold liquid nitrogen—is one method for maintaining plant genetic stocks in seed banks. Can seeds withstand a really deep freeze and still germinate? Read more
Can Garlic Prevent Crown Gall?

Science Fair Project Idea
Scientific Method
Crown gall is a plant disease caused by the soil bacterium Agrobacterium tumefaciens. This project uses tomato plants to investigate whether garlic extract can prevent crown gall infection. Read more

Science Fair Project Idea
Scientific Method
If you have a garden, you probably know about snails (or their shell-less relatives, slugs). You may even be looking for a good way to keep them from getting into your garden and eating up the results of all your hard work. In this science project, you will take a scientific look at one method of discouraging this garden pest. Read more
Soil Structure

Science Fair Project Idea
Scientific Method
What variables contribute to the properties of the soil in an area? Investigate the role of climate, weather, topography, time, parent material, vegetation, and biological and chemical agents on soil formation. How are soils characterized? There are 3 basic particle sizes which create three basic soil types: sand, silt, and clay. Investigate the properties of the three different types of soil by observing grain size, shape, hardness, color, chemical composition, pore space, aeration,… Read more
Porosity
Add Favorite
Science Fair Project Idea
Scientific Method
Soils are made of particles of different types and sizes. The space between particles is called pore space. Pore space determines the amount of water that a given volume of soil can hold. Porosity is the percentage of the total volume of soil that consists of pore space. Compare the porosity of different types of soil. Which types of soil hold the most water? Can you see this under a microscope? Read more
