Homeschooler Catapult Exhibition, June 2014

The kids & I thought it would be fun to revive the catapult exhibitions we attended a few years ago, when they were too little to build any themselves.  So, here we go:

Catapult Exhibition
June 11, 2014 11AM
Location: TBA green space near North York Centre
Participants: Children educated at home in and around the Greater Toronto Area
Comment here or send me a message (iam at this domain) and I’ll build a roster of participants

Catapults go by many names: ballistae, trebuchets, onagers, hsuan feng, mangonels, petraries, scorpions, tormenta, and others.  What we’re looking for here is a ballistic device used to launch a projectile a great distance without the aid of explosive devices.  Put your thinking caps on, get your tools out, work out the maths and angles, and build away.

We are thinking of setting up a system to measure the distance the objects are thrown, and also an accuracy/target course.  Two categories: kid made only, and then the models which the adults helped with.  Ammo wise, plan to use something similar to an orange — we’ll update this after we’ve had a chance to test a few things out.   Depending on numbers we will either give everyone a chance to talk about their build in front of the group, or a set time where spectators can go from build to build and ask questions about it.

Ideally the space we pick in addition to the missile range will have some playground equipment for families with younger siblings, area to picnic for lunch, and generally hang out to make a day of it for those so inclined.  I have a great spot in mind, I just want to test out the range of our builds to get a sense of how much space we’ll need before I settle on it.  Don’t want any windows broken or near by roadways interfered with.

A site we like is DIY.org, and they have a Catapult or Trebuchet challenge you can submit your project to, or review some of the devices other kids have made.

Some books we’ve found at the library that have designs and plans and ideas on how to get started are:

Toronto_Public_Library_logoSpeaking of the library, maybe you’ll join us at our Wednesday afternoon homeschooler group at North York Central library (1:30-3pm in the storyroom).  We plan to cover a few topics in the next couple of months applicable to catapults (levers & fulcrums for example is set for April 9th’s session for example).
