Purpose The purpose of this experiment was to determine the effect of different concentrations of detergents of plant growth. I became interested in this idea when I had a to wash clothes for a week as a homework assignment and I was looking at the ingredients and noticed some of them were volatile substances. The information gained from this experiment will alert consumers

The following experiments with plants can be used progressively through the plant units in the K-6 science curriculum. They are all based upon growing seeds in a sterilized baby food or Snapple ® jar filled with 3/4 inch of unflavored gelatin to which a few drops of liquid house plant fertilizer has been added for nutrients.

to retrieve dirt). Soil is very helpful to humans and animals. It contains water and inorganic nutrients, which is provided for the plants. The plants then are able to give off oxygen so plants and animals can breathe.

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

Ectomycorrhizal fungi allow their host plants access to organic forms of N through enzymatic mineralization of the substrate and enhanced absorption of amino acids and mineral N. The cost to the plant is carbohydrates that support fungal growth and metabolism. Enrichment of soils with mineral N, as through atmospheric deposition, may affect the growth and function of these fungi by direct effects

The fats people eat can come from either plants or animals. Fats from plants and animals are similar in some ways but different in others. In the activity below, you can do some simple experiments to learn some fat facts!

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

The purpose of this experiment was to see how different soils affect the growth of a pinto bean. The information gained from this experiment will help produce more trees and plants faster, so they can clean the polluted air around the plant's area. Also knowing this information will help farmers produce more vegetable

My goals for this project were to find mathematical relationships in nature. I decided to conduct four experiments to find mathematical relationships: (1) in the number of flower petals and vegetable leaves, (2) in the leaf arrangement in plants, (3) in the number of spirals in plants, and (4) in shell shapes.

Fungi have evolved to use a lot of different items for food. Some are decomposers living on dead organic material like leaves. Some fungi cause diseases by using living organisms for food. These fungi infect plants, animals and even other fungi. Athlete’s foot and ringworm are two fungal diseases in humans. The mycorrhizal fungi live as partners with plants. They provide mineral nutrients
