In this investigation, students will be introduced to the concept of what it means for two things to be in proportion. Students will be using a Great White Shark that has been scaled down onto a drawing. In order to determine to which scale it was drawn, students will have to determine the UNIT RATE/SCALE of the drawing. They will then use this scale to draw a Megalodon (the Great White Sharks gigantic ancestor) to the same scale and get a feel for how big this shark ACTUALLY was! This investig
