Your Week at Camp

Galileo Summer Quest

Catapult Builders

This week, campers will harness the power of projectiles to build working wooden catapults. They’ll learn an array of carpentry skills, using hand and power tools to assemble frames and throwing arms. They’ll explore the dynamics of potential energy as they test and fine-tune their devices to propel objects to great heights, across long distances or with amazing accuracy. They’ll build targets and compete in an end-of-session launch off. After entering their large-scale catapults in the Tournament of Launchers, they’ll take home their fantastic flingers.

Project Spotlight


Innovator's Mindset Focus

BE COURAGEOUS: I freely share my creative ideas, and embrace challenges

Weekly Breakdown


Campers will get familiar with the tools they’ll be using to build their catapults, reviewing safety tips and practicing carpentry skills by building a simple target. Campers will need to be courageous to embrace challenges and learn new skills, and will begin building the frame for their catapult later in the day.


After finishing their frame, campers will create the torsion spring mechanism to power their catapult. Some parts may be tricky, but they’ll have a building partner who they can rely on for support. Once the foundation is completed, campers will be visionary and begin developing a clear vision for the customizations they’ll want to make to their catapult later in the week.

Ask your camper: How did you make your torsion mechanism? How will it work?


Campers will practice being collaborative as they brainstorm different bucket designs for their catapult. They’ll first test with a simple cup design, then build on the ideas of others to create a functioning bucket design that they’ll use in a collaborative competition.

Ask your camper: Were you able to build off the ideas of others today? Were other campers able to build off your ideas?


Campers will revisit their original design plans and choose what customizations are most important to them. They’ll build, test and evaluate as they add new features, making changes and redesigning as needed.


Campers will decorate their catapult and continue to make improvements in preparation for the end-of-session tournament. They’ll need to be reflective in order to fine tune their catapults, diligently recording results while testing, and writing notes of advice for the next week’s catapult builders class. At the end of the day, campers will be able to show off their catapult’s accuracy, distance, and consistency in the Tournament of Launchers.

Innovation At Home

  • Level up your fantastic flinger, or design a new siege machine, using the catapult tutorials at Instructables as inspiration.
  • Invite friends over for a catapult building session. Work together to design and redesign a mega-catapult, or build separately and face off in your own Tournament of Launchers.
  • Explore an existing passion – or try something new – at, an online community for kids to challenge their inner builder, maker, and so much more.

Galileo Innovation Approach

The Galileo Innovation Approach® (GIA) is our guiding principle. The GIA is at the core of every activity your kids do at camp, from Pre-K all the way to 8th grade. Having a Galileo Innovator’s Mindset, Process and Knowledge makes a lasting impact on the way children think, explore and create.
