It’s no secret that there are larger cars on the roads now. The majority of cars on the road where I live are SUVs, and several decades ago these didn’t even exist. Your students may not be able to imagine a time when they were unable to stand up in their cars. But ask you students to research the history of SUVs. Why were they created? How were they marketed to be so popular?
This infographic compares the same cars over a series of years to show how they have grown in length and height, as well as weight. What is the benefit of these larger cars? In science class, discuss aerodynamics, and try to figure out which cars have an advantage, cars from the 1950s, or todays cars. Try to find similar sized model cars and make a wind tunnel, showing students the stream of air. Use other things on cars, such as the slant of cars and spoilers to show them the benefit of these.
