If/Then blocks can be used to control a simulation. When you click the green flag, you will be able to move the colonist around the screen. When the colonist touches a tree, it will cut the tree down. The colonist will collect the timber, and the tree will disappear. New trees will constantly grow, so keep the colonist moving around to collect timber from new trees.
This project is part of the SCPS CS2020 initiative for 4th grade.
