My hypothesis is that classical music will help the plants to grow. I also believe that the plants that listen to country will have their growth stunted.

The idea behind a reference toxicity test is that the test organism, in this case lettuce seeds, will respond in a predictable manner to varying concentrations of a particular chemical compound. At some threshold concentration, all of the test organisms will be killed (or in this case, none of the lettuce seeds will sprout). In solutions that are more dilute, some level of inhibition will occur in

The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants.

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 dadís 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 purpose of this experiment was to determine whether plants grow better in water or soil. I became interested in this idea when I started my experiment last year, and looking through books for research. The information gained from this experiment will help gardeners know how to grow their plants healthier, taller, and faster. -------------------------------------------------------------

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

My hypothesis is that the plant with the soil temperature normal will sprout faster then the plant with the soil temperature higher and lower.
Difficulty: Elementary school
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 ģ jar filled with 3/4 inch of unflavored gelatin to which a few drops of liquid house plant fertilizer has been added for nutrients.

What do you think will happen if the plants are too close together? Will there be enough food, water, and sunlight. What else might be in short supply?

This particular project is inexpensive, safe, fosters student inquiry, and gives good results that students can discuss in their final assessment--a poster session that models a "Science Congress" The project lends itself to cooperative group work.
