![]() Your tween can learn more about catapult physics including the trebuchet, mangonel, and more. The decreased weight of the projectile was a much better match for the catapults we had. The kids followed the same steps as before but had much better results. Since we couldn’t change the angle of the catapult, we decided to try it with a lighter object, a marshmallow. If we had also increased the angle of the wood, we probably would have seen a bigger difference in the path. When you increase or decrease the speed or angle during takeoff, the trajectory of the projectile will change.Įven though we had varied the catapult sizes slightly, there wasn’t really enough difference between them to launch the objects we had chosen off into higher trajectories.īy increasing the speed at which they were launched (by stepping on the board harder) some kids were able to lengthen the distance they flew. It was obvious through the three attempts that trajectory is only changed by two things the speed at which you launch the projectile and its angle during launch. What the Kids Learned About Catapults and Trajectory This did send the animals the highest they had been, but it was still less than what everyone was expecting. ![]() On the final attempt, the kids jumped or stepped onto the end of the catapult as hard as they could. One of the kids stepped so hard, he broke his catapult in two! Some of animals moved further, especially for the bigger kids. They decided to try again, this time increasing the force by stepping harder. The animals went straight up into the air and landed close to the catapult. The kids put their animal on the end furthest away from the base and stepped down on the other one. We headed outside to test this hypothesis.įirst, everyone chose one of the catapults and a small stuffed animal to launch. They all seemed to think that the items they were launching were going to soar through the air and land many feet away. Catapult Trajectory Science ExperimentĪfter teaching the kids about trajectory and outlining the experiment we were going to do, I asked each of the kids what they thought was going to happen, their hypothesis. Some had a longer arm and others had a slightly thicker base. He made a variety of sizes so the kids could see if the size of the catapult made a difference to the trajectory. My husband took the wood we used for our lever experiments and cut it down to make catapults. I wanted to make simple catapults for the kids in our science co-op to use during our trajectory experiment. Do your kids love to study trajectory by sending things into the air with a catapult?Ī catapult is something you can use to launch something a far distance away, using the release of accumulated tension instead of explosives.MORE FUN SCIENCE EXPERIMENTS FOR MIDDLE SCHOOL.What the Kids Learned About Catapults and Trajectory.
