Seadragons Posted January 30, 2010 Share Posted January 30, 2010 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. Link to comment Share on other sites More sharing options...

CaptainPanic Posted February 1, 2010 Share Posted February 1, 2010 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. Link to comment Share on other sites More sharing options...

agalla Posted February 10, 2010 Share Posted February 10, 2010 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.
