Bean Experiment

1. Problem
     Does a plant grow better with kool-aid or water?

2. Background knowledge
    Plants need water, sun, and soil to grow. 
    Kool-aid is mostly water.

3. Hypothesis
    I think the plant will grow better with kool-aid because it has other things       in it like sugar and dye.
4. Materials
    - 2 two ounce paper cups
    - water
    - kool-aid
    - 2 beans
    - ruler
    - paper towel
    - graduated cylinder at least 10mL
    - paper
    - pencil

       Step 1- Gather Materials
     Step 2- Make sure both beans look, feel, and sound the same. (like when                   you drop them from the same height
     Step 3- Put an inch of the same type of soil in each cup
     Step 4- Put one bean in each cup about one cm. from the bottom of the                     cup.
     Step 5- Pour 10 mL of water in one cup.
     Step 6- Pour 10 mL of Kool-Aid in the other cup.
     Step 7- Repeat watering every day for three weeks.
     Step 8- Record your data every day and note changes in your plant.
7.Collect Data
   I had to make changes in my method because I had forgotten some of the materials and hadn't realized how important it is to make sure your beans are the same. I had also forgotten to mention you should record your data and should repeat watering every day in the first method.
9. Questions for Extensions
    Would the plant grow better if we had used sugarless kool-aid?
    Would the plant have grown better if it was watered every day instead of        just weekdays?
