This lesson moves you on to the next big programming construct: selection. You will be introduced to it initially through a flowchart that demonstrates how a condition can be used to control the flow of execution in a program. You will then learn about definitions for logical expressions and conditions. A short activity has been included to allow you to grasp how logical expressions evaluate. Next, you will complete a PRIMM activity where you investigate and modify a chatterbot.
