Trebuchet Toss
Young engineers work in teams to design and build their own trebuchets according to certain criteria; they must be able to launch a mini marshmallow accurately into a pie tin. Background reading material, a planning sheet for trebuchet...
Curated OER
Secrets of Lost Empires II -- Medieval Siege
Students design a working working model of a trebuchet and demonstrate the power of a Class 1 lever. They test their models by throwing grapes the greatest distance and raising and lowering bricks.
Curated OER
Medieval Catapults
Students design and build a working catapult or trebuchet to explore the concepts of force, motion, and distance.

Secrets of Lost Empires II-Pharaoh's Obelisk
Learners identify and analyze how levers work by raising a brick with a shish kebab skewer. Students present their work, explaining what did and did not work, including illustrations of the lever lift from different angles. Learners...
Curated OER
Fling It
Students investigate the best design using technology. In this science lesson, students construct a freestanding object with specific materials to be able to shoot a ping pong ball and a marshmallow. They have to adjust and...
Urbana School District
Projectile and Circular Motion, Torque
Introduce your young scholars to the concepts of circular motion, projectile motion, angular speed, simple harmonic motion, torque, center of mass, centripetal force, and Hooke's Law with a 86-slide presentation. The circular motion...

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.
Curated OER
The Catapult
Students identify the advantages and disadvantages of a catapult as a weapon. In this physics instructional activity, students construct their own catapult. They investigate how changing one variable affects results.

Teach Engineering: Trebuchet Launch
Students work as engineers to design and test trebuchets (in this case LEGO MINDSTORMS robots) that can launch objects. During the testing stage, they change one variable at a time to study its effect on the outcome of their designs....
TryEngineering
Try Engineering: Trebuchet Toss
A lesson through which learners design and build a small trebuchet from everyday materials. After building and testing their models, students will compete to see whose prototype produces the farthest launch.

Serc: The Physics and Engineering of a Trebuchet
In this simple machines lab students investigate how the trebuchet works using their prior knowledge of simple machines. Students then build a trebuchet and analyze the physics and engineering that goes into building and launching it.

Science Buddies: Effect of Trebuchet Arm Length or Counterweight Mass on Project
A trebuchet is a catapult that uses a counterweight to supply the energy for throwing. They were used in the Middle Ages for attacking castle walls. In this project, you build your own model trebuchet and investigate how design changes...
PBS
Pbs: Nova: Destroy the Castle
Design your own trebuchet catapult, launch the sandstone balls, and destroy the castle. Decide on the size of your projectiles, where to place your trebuchet, and other factors critical to success.

Teach Engineering: Launch Into Learning: Catapults!
Young scholars learn about catapults, including the science and math concepts behind them, as they prepare for the associated activity in which they design, build and test their own catapults. They learn about force, accuracy, precision...
TeachEngineering
Teach Engineering: Physics of the Flying T Shirt
Students are introduced to the physics concepts of air resistance and launch angle as they apply to catapults. This includes the basic concepts of position, velocity and acceleration and their relationships to one another. They use...
