 | Project title: Do ferns grow faster in cold weather? |
Difficulty level: | Middle school |
Main link: | None |
Hypothesis:
My hypothesis is that ferns grow faster in cold weather. I base my hypothesis on past observations that I have made.
Materials:
3 young ferns in pots of the same size.
3 rooms with air conditioning
water
Measuring tape
The Procedure:
I placed one pot in each room.
Adjusted the temperature in the rooms to 15 degrees Celcius, 22 degrees Celcius and 28 degrees Celcius respectively.
I watered the pots twice a day with 200ml of distilled water
I ensured that the lighting conditions were the same for each room.
After 2 weeks, I measured the lengths of each fern (the ferns were the same size to start with).
Results:
The fern in the room with the temperature set to 15 degrees grew the fastest.
My hypothesis has been proved correct.
