Popsicle Stick Chain Reaction: a carefully laid network of popsicle sticks results in an awesome display of kinetic energy as the sticks fly apart.So, for today's STEM fun, I started with the fact that we have popsicle sticks and went hunting through the Science Buddies library of STEM activities for fun activities to do with popsicle sticks. What do we have at my house? Popsicle sticks (aka craft sticks) - we have lots and lots of popsicle sticks, which turns out to be great because they're quite handy for all sorts building and science projects. But that approach is not an option right now, so I'm getting better at making do with what we have at home. I like to decide what I'm making and then go gather the things I need - even if that involves a trip to the store. An object in motion stays in motion until gravity pulls the object toward the ground, and it stops.Are you the kind of person who starts with the end product and then figures out the list of things you need to make that happen, or are you the kind of person who looks around at what you have and then uses that to inform the end product? The last two months have taught me that when it comes to cooking, crafts, and science activities, I tend to be the former. When the inner tube stops, the projectile continues to move forward. This is Energy of Motion.Īny projectile placed inside the inner tube will move at the same speed as the outer tube. Releasing the inner tube converts this energy to Kinetic energy. Tension builds up and creates Potential Energy. Pulling the inner tube out towards you, causes the elastic to stretch. How does changing the projectile change the results? What do you think lead to these differences? HOW DOES A CATAPULT CANNON WORK? Launch a different projectile each round. Measure and record the distance it travelled with a tape measure. This is a great activity to do in groups. To do this, simply create a starting line to ensure everyone is standing the same distance from the target. The person who gets the most points/distance, wins! You can even assign points based on distance. APPLYING MATH SKILLSĪdd some extra STEM challenge to this project by having students put their math skills to use while playing the game. Ready, aim, fire! The winner is the person who hits the target the most times. In each round, everybody must fire the same projectiles to ensure a fair game. Don’t be afraid to challenge your students to come up with their own design innovations they think will increase performance. You can have each student build their own catapult cannon, or they can work in teams. The point of the Catapult Cannon game is to see how many projectiles hit the target, in 1 minute. Bean finding a solution for two tennis players who have hit their ball out of the court, by using recyclables from the trash and making a catapult to get the ball back to them.
Bean has some STEM skills? Watch the clip below of Mr. Bean, whom we have all grown to love, always brings a smile to our faces with his funny tactics. That means we need more force and energy.įor our project inspiration we turned to a beloved character, Mr. So for this project we wanted to build a catapult that shoots far. Now we all love the simple Popsicle Stick Catapult, it is a simple STEM project but the results are not always as impressive as we would like.

HOW TO MAKE A SIMPLE CATAPULT THAT SHOOTS FAR Learn more about the catapult in our Craft Stick Catapult project. In modern times, the catapult has become a well loved STEM challenge in classrooms around the world.
It was one of the most effective weapons used by the army during the war. It launched stones, spears, and other projectiles, to destroy a target in the distance. Thanks!
