Have you ever thought about how many parts of the computer have similar functions to parts of the human body?
In my PowerPoint I have made an interactive and fun way to look at the functions of the computer and to pick the similar functioning body system/part.
It's interactive and can be used on a projector or on a whiteboard.
Students are posed with a body part and asked to pick from the list a limited list functioning part of the computer.
When a wrong choice is made, a sound that denotes an incorrect answer is heard. Applause is the usual sound for the correct choice.
