Plant Growth

	Project title: Plant Growth
Difficulty level:	Elementary school
Main link:	None

Hypothesis:

My hypothesis is that regular tap water would be best to grow plants with. Other liquid I am testing with have either too much acid, or too much sugar.

Materials:

1. 4 angel plants
2. Some coke, milk, orange juice, and regular tap water
3. a cup to pour the liquid on the plants

The Procedure:

1. First, I watered the each of the 4 angel plants, with, coke, milk, orange juice, and regular tap water.
2. Then, I waited until 3 more days--since angel plants have to be watered only twice a week--to water the plants again, with the same type of liquid.
3. I recorded all of what was happening with the plants, and which one is living the longest.
4. I repeated this procedure over and over again, until the plants either died, or lived.
