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.

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

Pea Disease Of Central Washington
PURPOSE The purpose of this experiment was to determine how diseases effect pea plants, and what disease is most common. I became interested in this idea because I wanted a project that related to where I live, and I wanted to find out more about my dad’s work at Del Monte and what goes on there. Pea growers can use the information gained from this experiment so that they know what soi

The effects of tap water, mineral water, and seltzer water on the germination and growth of radish seeds.
How will tap water, mineral water, and seltzer water affect the germination and the growth of radish seeds? My hypothesis is that radish seeds will best germinate and grow in mineral water. Mineral water may have fewer contaminants that can hurt the germination of the seeds and perhaps this absence will help the growth of the plants. I also think that tap water will have a detrimental effect on bo
