A Screamingly Good Science Lesson
Elizabeth Kibler
1Amusement park rides give us thrills, exhilaration, and delight. If you pay attention, these rides can give you something else—a science lesson. Roller coasters are amazing rides that can twist and veer until you scream; however, these rides can also help to show us how types of energy work.
2Think about the first part of a roller coaster ride: A machine slowly pulls the cart higher and higher on a hill on the track. As the cart gets higher, it gains potential energy. Objects gain potential energy by being lifted farther from the ground. Potential energy is stored energy. The higher an object is from the ground, the more potential energy it has.
3When the cart reaches the top of the first hill, not only are riders’ stomachs screaming for mercy, but also the cart is at its maximum potential energy. Without warning, the energy-loaded cart begins to descend the first hill. As the cart careens down the hill, it has kinetic energy. Kinetic energy is different from potential energy. Kinetic energy is the energy of motion. All objects in motion have this energy. The kinetic energy propels that cart down the hill. Eventually, the cart will fight the forces of gravity and travel up another hill. On this uphill journey, the cart again begins to gain potential energy. The cart switched from potential energy, to kinetic energy, and back again. Therefore, a roller coaster ride is just the converting of kinetic energy and potential energy.
4After the first collection of potential energy, the cart does not use ropes, pulleys, or an engine. The cart, its wheels, and the laws of science are the only things that keep carts rolling firmly down the track. The air brakes on modern roller coasters bring the cart to a safe and smooth stop. If, however, a roller coaster had no brakes, it would ultimately stop on its own. The friction between the wheels and track and the friction between the cart and the air would eventually make a coaster stop. Think about a super ball. Although it gains potential energy every time it goes up, it eventually stops bouncing. In much the same way, the roller coaster cart would cease to move.
5Today, amusement park owners continuously try to outdo each other with bigger and better coasters. They believe that the more screaming their patrons do, the better the ride. Although the new rides of the day are going beyond what many thought was possible, it is all a matter of science. So, the next time you find yourself about to plunge down a gigantic roller coaster hill, try to think about the science of the amazing ride. Or, if you can’t stomach that much thought, just hold on and enjoy the ride.
Question
Mr. Osorio is a science teacher who is making a presentation to the school board to address the problems of low student interest and even lower student test scores in science. As an answer to these problems, he presents an argument that all science classes should go to at least one field trip per quarter, beginning with a trip to the newest roller coaster ride in the state!
How could he BEST connect the passage, A Screamingly Good Science Lesson to his argument?
Responses
A as a counter-argument that field trips can be inexpensive and safeas a counter-argument that field trips can be inexpensive and safe
B as a counter-argument to demonstrate science is as important as social studiesas a counter-argument to demonstrate science is as important as social studies
C as an example of an activity that can teach science and be fun at the same timeas an example of an activity that can teach science and be fun at the same time
D as an example that potential energy and kinetic energy are valid topics of study
