I. Problem/Question
A student thinks that a difference in the temperature of a room can have a noticeable affect on the rate of mitosis in a plant.
II. Hypothesis
An injured plant in a room at a less than ideal temperature will have a slower rate of mitosis/repair, plants in a room at a more than ideal temperature will repair/undergo mitosis faster, and plants in a room at an ideal temperature will have the fastest rate of repair, because if it's too cold the body of any creature begins to slow down and with it it's cells slow down, but if it's too hot, the cells will work faster but they may also die in the process, which is why it would be better at an ideal temperature because it would not be too cold and it would be warm enough to speed up it's rate.

IV. Experimental GroupsControl Group: Set of 3 injured plants in a room at an ideal temperature.
Experimental Groups:

V. Experimental Procedure
- Gather and injure 9 plants of the same species and age.
- Put three of the Plants in a room at ideal temperature, place another set of three in a room at less than ideal temperature, and the last 3 in a room at more than ideal temperature.
- For one week, water all of the plants and monitor the repair rate/rate of mitosis in the injured section of all the plants, document the results.
VI. Materials List
- 9 plants of the same species and age
- 3 rooms with temperature control in which to place the plants
- Any tool capable of harming but not killing a plant and it's cells.
VII. Expected Results
I expect that the plants in the room at an ideal temperature will heal faster by a slim margin. They would repair by one or three cells faster than the plants in the room that is in a more than ideal temperature because the temperature of the more than ideal room could be too much heat and could negate most of it's positive results and a room at a less than ideal temperature would be generally cooler than most rooms and plants tend to not fair well in cold weather. If my hypothesis of an injured plant in a room at an ideal temperature will affect it's rate if mitosis is true, i will see an increase in the rate of mitosis/repair as measured by how much of the injury on the plants are healed.
