Combining kinetic energy with a simple machine makes a task like hurling a piece of candy very exciting! Looking for more STEM activities?īe the first to know about new National Inventors Hall of Fame® STEM activities by following the Camp Invention Facebook page. This stored potential energy transfers to kinetic energy as the candy is launched. How does a catapult get its energy A catapult gets energy either from the twisted ropes or the rubber bands. Catapults use stored potential energy to eject the candy corn across the room. Kids will have a great time launching mini marshmallows across the room while learning about potential and kinetic energy. They will modify their catapult in order to produce the best launch possible. There are four parts to a lever: a rigid bar (arm), pivot point (fulcrum), the object being moved (load force) and the force applied to move the load (effort force). STEM Project for Middle School6th, 7th, and 8th grades.In this activity, students will work in groups to create a catapult from popsicle sticks. Here are 3 tried and true catapult designs that are easy to build and test. The purpose of a lever is to make a load (in this case, candy corn) easier to move. Check out how you can make a simple popsicle stick catapult with materials you probably already have at home. Why does a catapult fling candy so far? Catapults use a simple machine: the lever. or allow students to use existing art supplies and items from the recycling bin to complete the challenge Provide the class with a materials bin including rubber bands, pipe cleaners, binder clips, plastic spoons, activity sticks, etc.Split the students into teams of two or three with the same 20-minute period to build their catapults together.Read more about the science behind the catapult and simple ways to create a catapult science experiment below STEP 3: Test and measure how far each item goes when flung from the catapult. Want to take this activity into the classroom? Use these modifications to the above at-home instructions to have fun while learning with the whole class! STEP 2: Hand out supplies to each individual or in small groups, and build a Popsicle stick catapult following the instructions below. Redesign your catapults if you are not successful the first time! Next, try launching marshmallows, other candy or soft toys to test how materials of different weights travel different distances! Educators: Use this activity in the classroom with these modifications! Cheer when the candy lands on the target. Have your family count down from 10 as you test your catapults. When everyone has finished, set up a launching pad and a target 10 feet away. Give your family 20 minutes to build their catapults. Look for items you can upcycle to build a catapult! Simple machines are everywhere. Clothespins, spoons and scrap wood work great, but don’t stop there. With a parent’s permission, search the basement, recycle bin, junk drawer and garage for items you can use to construct your catapult. Swap game night with invention night and kick it off with this fun idea! Tell your family that today’s challenge will be to catapult candy 10 feet. Objects found around the house or classroom.Candy (or other soft, non-breakable items).When you meet your goal, keep the excitement going by testing with other items, such as small, soft toys! Materials Needed This fun STEM activity is kid-approved! Create a catapult and set goals to see how far your catapult can launch a piece of candy.
