Plant growth
 
How does the strength of weed killer affect the plant growth?
Introduction:
The first time that I heard about weed killer this question popped in my mind, How does a weed killer know which one is a good plant and which one is a weed? Actually what is the difference between  weeds and other plants? They are all plants (as far as I know). 

So this project is a good opportunity for me to find out the difference between weeds and other plants. Also, I will find out if weed killers can clearly distinguish between weeds and other plants, because if they don't, other plants will also get hurt or get killed by weed killers.

 
 Project description:
In this project we will design and perform experiments to show the effect of weed killers and how they affect plant growth.
