Mitosis Experimental Design
I. Problem/Question
Temperature might affect the rate of mitosis in plant cells. Design an experiment to test this hypothesis.
II. Hypothesis
I believe that if a plant is put in colder temperatures or hotter temperatures than ideal, the temperature may affect the growing of the plant and if I'm correct, I will see the plant in different temperatures growing slowly as measured by plant height.

IV. Experimental GroupsControl Group: A group of plants receiving ideal temperatures (i.e greenhouse).
Experimental Groups:

V. Experimental Procedure
1. Obtain three plants, name them ''group 1'', ''group 2'' and ''group 3''. Measure their height.
2. Put "group 1" in a greenhouse with the ideal temperature to make a plant grow, ''group 2'' in a 15ºC less than the ideal, and ''group 3" in a 15ºC hotter than the ideal.
3. Water each plant every 12 hours with the recommended amount of water.
4. Record the plants' height everyday for one month.

VI. Materials List
- Three plants
- A greenhouse
- Water
VII. Expected Results
I would expect to see that the group that got the ideal temperatures (group 1) would be the tallest because if plants (group 2 and group 3) don't get the ideal temperature, they will grow slowly. Plants need their ideal temperatures to grow and be healthy, an example is when interior plants are put outside, the plant will grow slowly or die because the outside is no its ideal temperature. If my hypothesis that hotter and colder temperatures will affect the plant height is true, I will see the plant growing slowly as measured by plant height.
