“I liked that I was able to build different catapults.”
-Jacob French, participant

“Catapult Engineering is non-stop, hands-on physics fun with a medieval flair. The kids got to work on their building, teamwork and critical thinking skills without even realizing it.”
-Lorraine Olendzenski, mom

What we do at Catapult Engineering!

Children are grouped into teams that build the trebuchet seen in the photo above. With adult supervision the trebuchet is tested and used in outdoor medieval challenges. Engineering drawings are used to guide the teams in assembling the trebuchet.

The teams do all the figuring, aiming, positioning and loading in preparing to knock down a mock castle wall. The lead instructor, however, is the one who sets the trebuchet before allowing the release of the siege machine. Safety first.

“The best part was building my own table-top catapult! It was awesome!”
-Silas Green, participant

● develop team building & leadership skills
● read & follow plans
● solve engineering problems on the field
● tweak the trebuchet for maximum performance and rule the kingdom
● discover structures, physics, statics, mechanics, joinery, simple machines, construction and more
● use tape measures, squares, levels, wrenches, levers & fulcrums, wedges, pulley blocks and mallets


Each child also assembles her/his own take-home table-top catapult. These are used for indoor games.

“I wish we had this when I was 10!”
-King Richard I of England (1157-1199)

“I liked that I was able to be creative & paint & design my medieval banner.”
-Aynsley French, participant

Outdoor field games add to the fun.

Inside, children get to unleash their creativity by producing medieval themed art.
