I need help with an experiment. My science experiment topic is on plants and I need help with a good question that will last over a period of eleven weeks. I need a good question by Monday and hope for a medium difficulty experiment so it is easy but not too easy for my strict science teacher.

Ask your teacher,Why dont plants grow upside down? Does gravity play a roll

or does UV light which causes photosynthisis the reason? Good luck

I have picked my question and it is going to be do earthworms affect the growth rate of a(n) (Specific Plant Here)

Plants do grow upside down, i grow tomato plants upside down every summer

I'll link to another thread (click) which was also was about plants and a science fair.

The original question was more specific, but may be interesting none the less.

Ok Thanks for the help.

How about Plant population? overcrowding of plants in the ecosystem? How much space do plants need to have an abundant growth rate? Plant 10 seeds into a small container, 9 in the next container, 8 in the next and so on... Record the growth by measurements. Which seeds germinated first? This might be an interesting subject.
