How does acid rain affect seed germination?
The purpose of this experiment was to determine the effect of acid on seed germination. I became interested in this idea because I know that acid rain is becoming a factor in pollution around the world. I know this from books I've studied and news articles Iíve read

How does acid rain affect the growth of plants?
The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants.
Difficulty: Elementary school
How does nitrogen affect plant growth?
The purpose of my experiment was to determine the effects of water solutions that contain different levels of nitrogen on bean growth.
Difficulty: Elementary school
How does salt water affect plant growth?
This project was performed to determine how different concentrations of salt water effect plants. The test that will be performed will prove which concentration will have the worst effect. The hypothesis is that by measuring the plants growth each day, the largest concentration of salt will harm the plants the most.
Difficulty: Elementary school
How does temperature affect the rate of growth of algae?
The purpose of this experiment was to determine the effect of a certain species of algae when they are growing at different temperatures.
Difficulty: Elementary school
How does the quality of soil vary from one county to another?
My hypothesis is that the soil in Yakima County will have a higher liklihood of being loam soil than in Pierce County. I base my hypothesis on my observations that a lot of crops grow better in Yakima County than in Pierce County and the crops in Yakima County produce higher levels than in Pierce County.

How is the growth of cauliflower plants affected by different salts?
The hypothesis of this experiment is that the cauliflower plant that is watered with the water containing Epsom salt will have the shortest growth height and the smallest root system. The purpose of this experiment was to determine the effect of different salts on the height growth and root systems of cauliflower plants.
Difficulty: Elementary school
How is the growth of strawberries affected by the soil PH level?
Changing the pH of the soil, helps make different chemicals in the soil more accessible. The world is filled with many plants which thrive in many climates. Each species has it's own needs and preferences. The multiple types of soil, each supporting a different pH, grow different plants. This test is designed for the growth of strawberry plants because of the massive amounts of sunlight needed. Ot

How to grow plants from fragmentation
There are two basic types of reproduction of living organisms. One type, sexual reproduction, requires the union of male and female sex cells, or gametes (sperm and eggs) in the formation of a new organism. The second type is asexual reproduction in which there is no union of sex cells. In this project, you will study one kind of asexual reproduction by examining the ability of plants to reproduce

How to grow your own mold
Mold is a simple fungus. It gets its food from grains, fruits, vegetables and flesh. Mold begins as a tiny spore that lands on a food source like bread. Spores can be found in the air, on the ground and on you!
