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.

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
Medieval Catapults
Students design and build a working catapult or trebuchet to explore the concepts of force, motion, and distance.
Curated OER
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...
