Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!
Grass growing in a lawn is a physical property because it is a natural process of the grass changing in size and shape without altering its chemical composition.
Grass growth is not a chemical reaction but a chemical change because the grass will not go back to its original form after it grows. Like chemical change, a certain object will not go back or reverse it from its original appearance.

I would say a little of both. The consistensy of what grass is made of doesn't change,it enlarges, so it could be called a physical change. But to grow, the grass absorbes water and minerals and does photosynthesis, and creates large molecules, so this could be called chemical.
no
