What kind of change is cutting down a small tree into smaller pieces. Then, finding a section that isn't rotted or infested with termites. After that, stripping the bark and any other abnormalities. Then, whittling away at this section until you've created a 1/500th scale figurine of the Jolly Green Giant. Finally, painting it to create an almost exact replica, other than the size.
Physical Change.
