Water Balloon Catapult
Fire away! Using a couple of milk jugs, a dowel rod, and a yardstick, individuals build catapults to throw water balloons. Learners notice that the catapult is a simple machine. By making a target, the class has a chance to refine their...
Cornell University
Catapult
Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Design a Catapult
Just this once, it's okay to throw things in class. Out of craft sticks and rubber bands, pupils build catapults to launch an object of choice. This can be a ping-pong ball, a marshmallow, or any other small item. As long as it hits the...
Curated OER
Motion, Forces, Energy and Electricity
What a wonderful way to explore motion and forces! Learners design a catapult, after watching a video and discussing types of catapults. This is a comprehensive and complete lesson with links to supplementary resources.

Designing and Building Catapults
Seventh graders complete a challenge to create a catapult that projects a marble or other projectile at least one meter. While experimenting they apply the Four Question Strategy to answer the question, " How can I make one modification...
Cornell University
Catapults
Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome.

Build a Catapult
Studens construct their own catapult. In this history of catapults lesson, young scholars work in groups to make their own model of a catapult. Students use physics vocabulary terms explain how the catapult works. Young scholars test the...

Catapults!
Students work together to discover the relationship between the angle of catapults and the flight of different objects. They discover the heavier the object the more force is needed. They examine how engineers use this information to...

Catapults
Young scholars are introduced to the concept of a catapult and how it is used with the help of a media presentation. They use catapults in a large, open area and record the distances objects travel. Students use the scientific method...

Levers: Catapults
Students construct a catapult that shoots a cotton ball at least two meters using Legos, rubber bands, and plastic spoons. They discuss how the catapult works, and identify any problems they had with their experiment.

Kids Build Pumpkin-Tossing Catapult
Students read a news article about the creation of a catapult that will throw pumpkins. In this current events lesson, the teacher introduces the article with a discussion of catapults and a vocabulary activity, then students read the...

Newton Car
If a car gets heavier, it goes farther? By running an activity several times, teams experience Newton's Second Law of Motion. The teams vary the amount of weight they catapult off a wooden block car and record the distance the car...

Marshmallow Mania
In this science project worksheet, students create a catapult from a standard mousetrap that will deliver a small marshmallow to a target area. They score each other based on the landing position for each.

Marshmallow Catapaults
After a brief lecture on levers, torque, projectiles, and the five-step engineering design cycle, young physical science learners or engineers build catapults out of craft sticks. This is an open-ended exploration of what works and what...

Elastic Forces
Third graders predict and experiment to discover the amount of force exerted by a stretched elastic band. They construct a spreadsheet and make a bar graph showing the results of their experiment.
Curated OER
UFOs
Learners, in groups, construct a catapult. Then they conduct a series of experiments by catapulting a marshmallow, using different lengths of spoons, across the room. They predict, measure, and record the measured distance on a worksheet.

Exterior Ballistics
Young scholars explore velocity and trajectory. Using exterior ballistics rules, students predetermine the path of an artillery shell. Given equations and the firing angle, young scholars determine the velocity and horizontal travel. ...
PHET
Projectile Motion
Have you ever wanted to shoot someone out of a canon? This simulation gives you that chance! In addition to a human, you can shoot a car, a piano, a cannon ball, and many other items. Scholars set the angle, initial speed, mass, air...

Angling for Distance
Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile. Students launch baseballs on a football field and video tape the path of the ball.
