Procedure


1.      Place the given container on the scale, and zero it to ensure precise weight measurements.

2.      Place approximately 100 untreated Kohlrabi seeds into the container that was used to originally zero the scale. Then add or take out seeds until the scale reads 0.4 grams. You may not need to add or take out seeds.

3.      Repeat the process mentioned in "Step 2", 2 more times after the first so you have a total of three sets of seeds that weigh 0.4 grams each.

4.      Take 3 pieces of paper towel and cut each to the following dimension: 8”x12”.

5.      Use a Lumocolour permanent waterproof marker, (to insure the ink will not bleed), and write your group name. Along with that write the temperature type, (heating mat temp., fridge temp. or room temp.) on one half of the paper towel.

6.      Hold each individual paper towel piece under warm running tap water one at a time, until the paper towel is moist.
7.      On each piece of the moistened paper towel, place one of the three 0.4 grams sets of Kohlrabi seeds evenly. They should cover only one half of the paper towel, (the opposite side should have your group name on it as mentioned in "Step 5").

8.      Fold the paper towel half without Kohlrabi seeds on it on top of the half with the seeds so that the group name can be seen on top.

9.      Fold over the edges of the paper towel to ensure that the seeds will not spill out.

10.  Place the seed filled paper towels in their designated areas.

11.  Record any and all observations daily.

 Independent Variables
   The Independent Variable is the variable that stays unchanged throughout the experiment and is not influenced or changed by the dependent variable at any time during the experiment. The individual doing the experiment is in control of this variable.
1. Temperatures
  • Room Temperature
  • Heat Mat Temperature
  • Refrigerator Temperature
Dependent Variable
   The dependent variable is the variable who's results are influenced by the independent variable, and change over the course of the experiment. It is the variable that has the potential to change over the course of the experiment, and is what the people who are conducting the experiment use to either support or not support their hypothesis.
 1. Kohlrabi Seeds
  • Set 1
  • Set 2
  • Set 3
Control Variable

   The variables and factors that remain the same between the different sets of the dependent variable. This variable allows the experiment to be as real as possible because all sets of the dependent variable are identical, so no differences can change the outcome of the experiment. 
1. Factors that remain identical between all three sets of the dependent variable.
  • Amount of time Kohlrabi seeds are exposed to the temperatures.
  • Size of paper towel used to enclose the Kohlrabi seeds. 
  • Type of seeds used (Kohlrabi, untreated)

Control Group
A set of the dependent variable that is identical to the ones being tested, but is not tested so that the results between the other sets can be compared with an original and untested set and conclusions can be made.  


 1. The control group is none existent; instead, the results will be compared using all
three of the sets of the dependent variable.
