Pushing your six sticks the other direction creates a greater angle between the launching stick and the base. This results in a cotton ball aimed more upward than forward. Moving the stack of six sticks closer to the launching cup makes the launching stick lie flatter. In the case of your catapult, the cotton ball probably flew higher and farther. They will then learn the Science and Math behind this technology and become engineers and build.

Bending farther means more energy gets stored in the stick, and when you let go, all this stored energy is converted into energy of motion, so the cotton ball flies through the air at a higher speed. In this class learners will learn the history of catapults. Optimized to sit on any flat surface or to be mounted on any wall, Stem Wall is a high-quality conferencing bar array that turns any environment into a professional conference room. Maybe you felt you needed to exert more force or work harder to bend the stick farther. Pushing the stick down farther takes more effort from you. Most of this energy transfers to the cotton ball, which shoots through the air. When you let go, this energy is released and converted to energy of motion. When you bend your stick, you load your launching stick up with energy. Whatever you decide to do with this fun St.Do you get similar results each time? Is what you observe what you expected? Can you explain why?ĭid you see your cotton ball fly higher and farther when you pushed you launching stick farther down? Let your kids get creative and place the pots of gold wherever they want! If your kids are anything like mine, then you might find them putting a pot all the way across the room to see if they can shoot the marshmallows that far. However, you can assign the farther pots more points or assign random points to the pots to make the game even more interesting! We just assigned 1 point every time someone gets a marshmallow in a pot. You can also assign point values to each of the mini pots of gold. We just used whatever marshmallows we dug out of the Lucky Charms cereal box, but you can have one kid using only four-leaf clover marshmallows, and another using only rainbow marshmallows, etc. Patrick’s Day activity even more educational, you can have your kids sort the marshmallows before launching them. Using 2 rubber bands, tie the craft sticks together on both ends.
3.) Next, place a popsicle stick under the spoon handle with the spoon facing up. Wrap each rubber band around several times to make it nice and secure. 2.) Second, secure each end with a rubber band. If you would like more popsicle stick catapult ideas, check out additional designs here. Snowball Catapult STEM Activity Instructions: 1.) First, stack 4 popsicle sticks. I will provide step-by-step instructions for one of the easiest ways to build one. There are many ways to build a popsicle stick catapult.
