Catapult Challenge - Scholastic
Catapult ChallengeThe problem: You need to move some materials from one place to another with thehelp of a simple machine. Keeping what you know about force and motion in mind,your challenge is to design the catapult that will move your materials the furthest.Your Goal: Using supplies available to you in the classroom, build the catapult thatwill launch your chosen projectile the furthest.First, find the answers to these question using the reference tools available to you—iPads and laptops. You have 15 minutes.1. What does a catapult do?2. What is a projectile?3. How does a catapult work?4. What type of simple machine is it? (incline plane, lever, pulley, screw, wedge, orwheel and axle) How do you know? http://www.mikids.com/Smachines.htm
Research: Research different ways to build simple catapults. You might try online research and/or trial and error. (Google how to make acatapult for kids) Decide what materials your team wants to use to build their catapult You have 20 minutes.The materials you will have to choose from to create your catapult are listed in thetable below.MaterialLimitsLarge and small craft sticks10 altogetherRubber bands6 or lessPlastic spoon1Binder clip1Plastic cup1Clothespin1Materials you have on your desk right now Up to 3Your projectile will be taken from a bag of assorted valentinecandy.Materials we chose:MaterialLarge craft sticksSmall craft sticksRubber bandsPlastic spoonBinder clipPlastic cupClothespinMaterials you have on yourdesk right now.1.2.3.Sketch:QuantitySelected
Design: You have 30 minutes to build, test and modify your catapult.Keep in mind: What is your design goal?How much force will your design require for a successful launch?What angle launches the object the furthest?Which projectile launches the furthest?Have you tested a different way?What improvements can you make?You may test every projectile, but you may only use one in the final launch.NEVER aim your projectile toward a person.Test Data:TestNumber1.2345678.Projectile used(small candy heart, large candyheart, sweet tart, gummi heart ormarshmallow.)Change you made and why.Distance in inches

Observations Based on Data Evidence1. Overall, which projectile seemed to launch the furthest? What do you think madethat one go further?2. What one material do you think made the biggest difference in creating asuccessful catapult? Explain why you chose that one.3. What forces were used to move the projectile—pushes or pulls? Explain youranswer by giving examples using your catapult design.4. What happens to the projectile if no force is applied? Why?5. What would you do differently next time and why?
Catapult Challenge 2Your Goal: Using supplies available to you in the classroom, build the catapult thatcan launch a projectile to hit a six-inch target that is 36 inches away.You have 15 minutes to build, test and modify your catapult!1. How is this catapult different from your last one?2. Explain why your team made the changes you did. What were you thinking?Test Data:TestNumber1.234Projectile used(small candy heart, large candyheart, sweet tart, gummi heart ormarshmallow.)Changes you made andwhy.Did it hit thebull’s eye?Yes/noHow manyinches awayfrom thetarget?
Questions to Discuss What type of energy did your catapult use?What makes the projectile go the furthest?What projectile goes the furthest?What makes the catapult more accurate?Does mass affect the results?How do objects move?How did the catapult set the candy in motion?Which challenge did your catapult meet best, accuracy or distance?What happens when the arm of a lever is shortened or the load is moved?What happens to the force needed to make the load move?What happens when you move the fulcrum?What is the relationship between force and distance?What happens when you adjust the angle?

pumpkin catapult/trebuchet activities. I understand, and I am aware that pumpkin catapult/trebuchet is a hazardous activity. I understand that pumpkin catapult/trebuchet and the use of catapult/trebuchet devices involve a risk of injury and that there is a possibility that the child could be injured while participating in this activity.
Popsicle Stick Catapult Activity Students will build a catapult and explore how a catapult works. Materials needed per student: 5 popsicle sticks Bottle cap (or a plastic spoon if preferred) Binder clip or nametag clip Glue (super glue preferred with adult supervision) Small objects for testing Directions: 1.

(CCSS.Math.Content.7.RPA.2). This prepares the students to use those same rubber bands in their model catapult design as they will be tweaking the distance the rubber band will be stretching - and therefore the potential energy of the band, the force upon the supporting structure of the catapult, and the force applied
Incidentally, the trebuchet was also used as a punishment device called the ducking stool. People were placed in a seat at the long end and successively ducked into a pool of water. The catapult is still in use today, although radically different from those used in history. The modern catapult is used to launch aircraft from the deck of
a catapult and a trebuchet? Objectives Students will be able to: Understand the goal of a simple machine. Compare how two different kinds of catapults function. Design and create a mini Mangonel catapult, and explain the force behind its launch system. y Defining the Problem y Designing Solutions y Creating or Prototyping y Refine or Improve
Brené Brown has taught us what it means to dare greatly, rise strong, and brave the wilderness. Now, based on new research conducted with leaders, change makers, and culture shifters, she’s showing us how to put those ideas into practice so we can step up and lead. The Sum of Us: What Racism Costs Everyone and How We Can Prosper Together Heather McGhee The Sum of Us is a brilliant .
