Bottle rocket experiment aims to encourage healthcare careers

A group of Birmingham-area middle school students responded immediately.

“Compounds!” said one.

“Chemistry!” said another.

“Blowing up things!” said a third.

Caruthers loves seeing this excitement for science and she wants it to continue. And that is why she is involved with the annual Health Careers Opportunity Program which is designed to increase the number of students from educationally or economically disadvantaged backgrounds who enter medical and health professions.

In this session, more than 50 Birmingham middle school students, guided by Caruthers, used a mini-container, paper, water, antacids and science to build and launch bottle rockets at the UAB School of Health Professions.

“We are taking water and putting it in a canister that the students made look like a rocket. Then we add an antacid and close the canister,” said Caruthers. “The reaction between the water and the antacid causes gas. This allows bubbles to rise to the top of the canister which will then cause the canister top to pop off and that will shoot the rocket up.”

Consider this a metaphor for these students. Learning that science is fun is the Law of Action. Pursuing a science-based healthcare career is the Law of Reaction.

In the end, the student’s bottle rocket experiment sputtered. Whether it was a top not on tight enough or the water spilling out when the student set up the rocket, the rockets were mostly grounded. Caruthers told the students in the Laws of Action and Reaction – she calls this a weak reaction.

She went on to explain that this is exactly why scientists experiment. And this is why scientists do not give up. Caruthers hopes that lesson, above all, is the one these kids take home.

“We want them to know that if they work hard and don’t quit then they can be a physician assistant, or a physician, or a nurse, or a physical therapist,” said Caruthers. “But they must know science because science is important for all of these healthcare careers.”
