I am doing a school science project and i'm trying to find out if darkness makes plants grow taller. Also what is a good way to test this?

Plants will grow taller in the dark, at least initially, despite what the other answers think. They spend all of their energy looking for the light, hence grow very tall and spindly with few leaves (referred to as etiolated).
However, if you keep them in the dark for too long they die, obviously.

well i can say that plants doesnt get taller during the darkness . but i can tell u that there is things can make it grow out by useing water and feeding it with plants food and also having it outside close to the hot sun do make the plants grow taller sizes . maybe you can get some books about how the plants does grown by going to the school Library and check out some good books and take some with you at home and just studying about them and might help youre science project and you will get good grade doing a good work .

Seems have a big turn in a person's life. The external form of a person is ideal in the eyes of the planet when every feature is assembled in flawlessness or very nearly there. Of all of them, height represents an important role.
Height is not just lots is one of the critical standards in plenty of areas: sports, being a part of the security force, wooing someone, obtaining a work or just bolstering one's assurance therefore, if you want to be slightly taller you just have to use this program https://bitly.im/aL3he , grow taller 4 Idiots.
The combination of proteins with growth hormones, could certainly lead to a taller stature and this really is what you would study on this book, how you can set this mixture used because this system really work for nearly all people.

Darkness won't make plants grow taller, i dont' think at least from what i know of plant physio. However, darkness will kill plants, cus they can't make any food.
A good way to test it? have a number of plants seedlings. Have half of hte grow in normal light, and the other half grow in darkness. compare height after a little while. Don't make it complete darkness, or else plants will die because they don't have any energy to undergo photosynthesis

Plants do not grow in the dark. Photosynthesis is a light driven reaction. Except the seeds sprout and grow in the dark. The nutrients for this growth are stored in the seed.

I actually used the program that "Skippy" person speaks of. It really does work. That same website, http://www.growtall.pcti-system.com .. I played basketball in college, and I used that to gain a couple in height. A total of 2.5 inches. After that, it seemed to plateau though. I could not gain any more than 2 1/2, no matter how hard I tried. But those inches really gave me an advantage in my games. Well worth it.

Initially; yes. They will stretch looking for light, but they will be weak and spindly as well.
