![]() Is there an effect of where the pom-pom is in the cup when it is launched?īesides increasing the number of popsicle sticks is there another way to increase or decrease the catapult’s tension such as looser/tighter rubber bands and using more pressure when launching. How does the placement of the popsicle stick bundle change the performance? How does the tightness of the rubber bands affect the catapult’s performance? Observe how the distance changes as the tension increases.ĭistance: Can you get the pom-pom to go further?Īccuracy: Can you get it to a specific location such as in a cup or container located somewhere in the launch site Increase the tension of the catapult by increasing the number of popsicles in the bundle. Place the bundle between the catapult’s two popsicle sticks, near the rubber band at the bottom. Have students start with the 3 popsicle bundle. Step by step video instruction how to make homemade easy mini medieval weapon that really shoot. Take 2 more popsicle sticks and position them 1 above and 1 below the stack of 5 popsicle sticks. How to build a trebuchet catapult out of popsicle sticks. Have students line up with their catapults at the beginning of the launching site. Building a popsicle stick catapult is an awesome STEM activity that combines creativity and learning. Take a stack of 5 popsicle sticks and wrap a rubber band tightly around each end. ![]() If desired, measure out a distance of 10 feet, placing a line of painter’s tape at each foot. Before you start making the catapult take a look at the popsicle sticks and make sure they arent cracked or weak. The rubber band, when cut, should be at least 5 inches in length. Ten popsicle sticks, a ruler, a pencil, scissors, a rubber band, and a roll of masking tape. Repeat this step so each student has bundles 3-10. Here are the materials you need to make this catapult. Here’s a fun (and effective) catapult to build out of popsicle sticks, hot glue, and a few other basic household supplies. Repeat those two steps for various sizes: Make bundles of 4, 5, 6, 7, 8, 9, and 10 popsicle sticks. Release the spoon to launch your pom pom Using the Craft Stick Catapults. Hold the catapult with one hand, and use the other hand to pull the spoon down. 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. Double tie the bands to keep the sticks tight. Rubber band a spoon to the upper popsicle stick. Make a stack of 7 popsicle sticks and use rubber bands to tie them together on both ends, about ½-inch from each end. Pre-make as many catapults as needed for each studentīundle these together with a rubber band at each end. Rubber band the stack of popsicle sticks to just the upper popsicle stick. My Hypothesis: Just as scientists and engineers do, you are going to complete a series of tests before trying to get your pumpkin into the wagon Fill out the information below as you complete your testing trials. Step 3: Fit the stack of eight sticks that you made earlier in the gap. between force of your catapult and the distance your pumpkin will travel. But this time, only tie one end and leave the other end open. ![]() Step 2: Take two more popsicle sticks, and tie them together with rubber bands. ![]() Tape or glue the cup near the top of one of the two sticks, but leave a little room at the end Step 1: Take eight popsicle sticks together, lay them out horizontally, and tie both ends of the group tightly with rubber bands. Thereafter, it became a key weapon in warfare and remained so up through mediaeval times.Lay two popsicle sticks on top of one another and wrap a rubber band around one end The Greek Dionysius the Elder of Syracuse, who was looking to develop a new type of weapon, invented the catapult about 400 BCE. Catapults were mainly used to lay siege to castles and fortifications during the medieval period.Ībout 400 BCE. The Catapult was used to launch projectiles a great distance, and remains one of the most effective medieval weapons during warfare. And when you release the stick, the potential energy turns into kinetic energy, “moving” energy! Then gravity eventually pulls the launched object back to the ground. So why is a catapult able to launch things so far? When you pull back the popsicle stick, potential energy, or “resting” energy gets stored up.
