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. Catapults use stored potential energy to eject the candy corn across the room. 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). The purpose of a lever is to make a load (in this case, candy corn) easier to move. 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.
#STEM CATAPULT HOW TO#
With this activity, they can learn how to build. Split the students into teams of two or three with the same 20-minute period to build their catapults together Exploring physics has never been so exciting for kids because everyone loves to launch stuff into the air. Catapult STEM Activity with Popsicle Sticks is a great way to teach your children about physics and engineering.Using a rubber-band-powered catapult you will send ping pong balls flying through the air. But only if you could aim it reliably With this science project, you will try your hand at catapult technology. 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! If you were in a raiding army in the Middle Ages, a catapult would come in mighty handy for taking down castle walls. 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. 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.
Look for items you can upcycle to build a catapult! Simple machines are everywhere. STEP 2: Hand out supplies to each individual or in small groups, and build a Popsicle stick catapult following the instructions below. 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.
