10 Easy Points?

Question

I have a project involving testing ONE factor that affects plant growth. I want it to be interesting as well as have something that would actually be important to test.

NOT...temperature, sunlight or water...as they are obvious

NOT...anything that doesnt have much use if tested...like music's affect on plants, or different soda's affect on plants

Answer 1

Acidic soil.

Answer 2

different top brands of soil

Answer 3

How about oxygen or CO2 levels (they may be difficult to monitor without specialized equipment)

Or pH level, which might be easier to manage/monitor

Or Depth of seed deployment

Or UV light vs sunlight vs fluorescent (I know you said no to sunlight, but this twist might be interesting)

Answer 4

ummm....

maybe music's affect on plants, or different soda's affect on plants

or even ...

temperature, sunlight or water

good luck

hope i helped

Answer 5

Talk to one plant and not the other. Seriously! Plants use carbon dioxide for photosynthesis, right? You exhale carbon dioxide as you talk, so the plant will make more food for itself. It sounds crazy, but when you think about it, the plant you talk to should grow faster.

It will be interesting, and it should actually work!

Answer 6

The acidity of the dirt. Certain plants like more acidic dirt (roses, etc.) while others prefer more basic. You could try different dirts- take the PH's of the dirts & plant identical plants with identical conditions except for the dirt.

Answer 7

Try having 3 plants: 1 growing by itself (far away from the other 2) and grow the other 2 with the same soil in the same place

See if the plants grow better alone or need some "company"

Answer 8

Cut off different parts (leaves, flower, bits of the stem) and see

Answer 9

Nitrogen content, which is very similar to the soil suggestion.
