![]() ![]() Even though I was aware of it after recording I did not have the energy to re-record with all steps. Please note that the “B” design video has some issues with audio quality. See the videos I created for students (A and B designs) at the end of this post. Please note that the students still required support, but it was a lot easier for me to circulate through the room and answer questions as needed rather than trying to keep everyone on the same page with an in-person demonstration. The videos allow students to pause as needed or even have students who were absent catch up without needing direct intervention from the teacher. This served to let students know which of the two designs they were building and gave them some independence to follow the video versus watching me build them in real time. I took time to record the step-by-step process to build each design so I could push it out with the lab report document. Try different sizes of pom poms or marshmallows to see which ones fly best.There was no real solution diversity to speak of overall, but there are two student designs that I chose to give them something to compare and discuss.Try to hit the structure and break it down. With a friend, create a structure out of paper or plastic cups, toilet or paper towel rolls.You can try to aim your launch at an empty toilet paper roll on a table.ģ.Release the spoon and watch the pom pom fly! Extra fun: Hold the catapult with one hand and use the other hand to push down the spoon. ![]() Place the pom pom onto the bowl of the spoon.Ģ. Launching objects from your catapult is easy, but please be careful to only use soft objects, to not aim at other people, and do not use around easily breakable objects.ġ. Add a button to the bottom of the handle where you’ll hold it down, some extra pom poms to the ends of the platform or the flag of your kingdom! Launching Now is another time you can decorate the catapult. You can adjust the bands to secure the spoon best.ĥ. Using 2 rubber bands, secure the plastic soon to the upper popsicle stick, one right below the bowl, one near the bottom of the handle. Place the plastic spoon on top of the free popsicle stick. Pull the 2 popsicle sticks apart and wedge the stack of 7 popsicle sticks between the bottom stick and the second stick.Ĥ. Make a stack of 2 popsicle sticks and use a rubber band to tie them together on one end only, about ¼-inch from the end.ģ. Double tie the bands to keep the sticks tight.Ģ. Make a stack of 7 popsicle sticks and use rubber bands to tie them together on both ends, about ½-inch from each end. In ancient times, catapults sometimes included the colors or coat of arms of the attacking army so you can create your own kingdom or copy the imagery of Rome or your favorite Greek city-state.ġ. Before you start making the catapult, you can paint or draw on each stick to give your catapult a unique look. Now that you’ve gathered your materials, here are 5 steps to build your catapult:Ġ. Let’s start making our catapults so we can see what Newton saw in 1687!ĬAUTION: Do not launch hard objects from these catapults! Do not aim at breakable objects either! So as much as we push down on the spoon of our catapult, it will spring back with that much force. His third law is a bit easier to grasp: every action has an equal and opposite reaction. In terms of our catapult, how fast our pom pom flies is determined by its mass and the force we put on it (i.e. Newton’s second law is actually a mathematical equation, but it states that the acceleration of an object is proportional to an acting force and inversely proportional to its mass (F=ma). He defined three foundational principles of physical science and mechanics called the “laws of motion.” Sir Isaac Newton was a British mathematician, physicist, and author in the late 1600s. Who is Newton and What Is a Law of Motion? Making these will train fine motor skills, examine Newton’s second and third laws of motion, and can be fun art projects. This popsicle stick catapult is not only easy to build for all school-aged children, but it’s also a fun toy after you make it. Bringing STEM activities into your home is easier than you think.
