Let's Investigate Roller Coasters!

Whether you have first-hand experience of the thrill of a roller coaster ride or you’ve seen these rides through pictures and videos, roller coasters always start the same: with a very tall hill that you are pulled up and then you zoom down the rest of the ride! But, there is not a giant hand pushing or pulling the cart down the track! Then, what is bringing the cart down and through the rest of the ride? Just like you, scientists and engineers have observed and questioned this concept in order to solve problems and make our lives easier and more enjoyable! In order to confirm or deny our ideas as to what brings the cart down and through the rest of the ride, we need to engage an investigation!
