Launching Into Learning: Eighth Graders Put Newton’s Second Law to the Test

In Dr. Denise Glenn’s eighth grade science classroom, Newton’s Second Law isn’t just something students memorize, it’s something they put in motion—by building and testing handmade catapults.

As part of a hands-on physics challenge, students designed and constructed their own catapults using simple materials like popsicle sticks and rubber bands. From there, the classroom quickly transformed into a lab of experimentation, where students tested projectiles of varying masses, adjusted launch angles, and measured how force impacts acceleration.

“Force times mass equals acceleration!” Evan H. ’26 called out when prompted—a clear sign that the concept is sticking.

By manipulating variables like angle, force, and mass, students are seeing Newton’s Second Law in action. Whether aiming to knock down stacked cup towers or land a projectile inside a target, each trial requires careful observation, data collection, and adjustment. Students record their findings as part of a lab activity, reinforcing the connection between theory and real-world results.

The challenge doesn’t stop at accuracy—it also builds problem-solving skills. Dr. Glenn encourages a “figure it out” mindset, where students iterate on their designs, collaborate with peers, and learn from failed attempts. The experience is intentionally open-ended, giving students ownership over both the process and the outcome. And yes—it’s as fun as it sounds.

“It’s really fun trying different angles and seeing what works best,” said Nolan B. ’26. “And honestly, knocking things over never gets old.”

With future challenges like bridge building on the horizon—and even larger outdoor launches planned—Dr. Glenn’s classroom continues to be a place where curiosity, creativity, and physics collide.
