EAST WHITTIER – Hillview Middle School seventh-graders took to the campus field for a hands-on learning experience, using math and science concepts to launch water rockets on May 24.
More than 140 students participated in the science, technology, engineering and mathematics (STEM) activity, with science and math classes combining disciplines to calculate the trajectory, flight time and altitude of the rockets.
“I liked having both aspects of math and science,” seventh-grader Kaitlyn Miranda said. “I used science to decide on my rocket’s design and I used math to measure how far it went and how successfully it flew.”
Students spent two weeks designing and constructing their rockets. In pairs, the seventh-graders created the water rockets using two-liter plastic bottles, duct tape and cardboard. Fins were constructed for the base of the rocket and a nose cone was secured on top to enhance stability during flight.
Three pairs set up their rockets on wood platforms connected to an air compressor, and tied a string to the launch pad. The rockets were propelled in to the sky using a combination of pressurized water and air.
“My rocket didn’t go as high on the first launch,” seventh-grader Jonathan Torres said. “I had to fix my fins because one tore and I redistributed the weight a bit. On my second chance it went a lot better, and I enjoyed seeing it all come together in the end.”
While the science students worked on engineering elements to design and test the rockets, math students observed to measure altitude and flight time. An art element was also applied to the activity with students designing their mission patches for the rockets. A sixth-grade class viewed the demonstration to understand what will be expected of them next year.
Hillview science teacher Marc Rizzo has coordinated the event for the last five years, and this year decided with math teacher Michael Hollon to combine both subjects for the rocket launch day.
“This year we wanted a fun way to connect math and science,” Rizzo said. “Students study the subjects separately but there is so much dependence with both disciplines. With students participating in both areas they can see both perspectives and gain a deeper understanding on what they are learning.”
Those unsatisfied with their launch, were offered a second chance to redesign the rockets and test them again after school.
“It is rewarding to see the students engaged in what they are learning and that they are enjoying it,” East Whittier City Superintendent Mary Branca said. “STEM curriculum is part of the well-rounded education we provide for our students. With the hard work of our educators, these experiences will help to shape students’ academic careers and set a precedence for their curiosity and learning.”
