We are going to do so many creative things this year, and the goal is to have everyone at their pace, not following the same thing for all folks.  But, one thing that is so important is safety.  We have so many ways that bad things can happen, much more than a regular class.  We have tools, parts, sparks, fragments, and your safety is so important.

So, before we use the tools and toys, we need to make sure we have safety procedures, because you never know what could happen.  For example, this girl never thought her hair would be an issue:  http://www.cnn.com/2011/US/04/13/yale.student.death/index.html?eref=m.

Part of safety is organization and clean up.  Leave a razor blade in the wrong place and blood is soon to follow!  We will place a priority on cleanup, as it's not only safe, but saves money!  We will review safety and cleanup rules, and you will not be permitted to work with tools, equipment and materials until you pass a test on it.

See the following document, and there will be more:
You will be tested on the safety concepts, but we will review them again, and add some conditions.

One aspect of safety also relates to actually saving money.  If tools and materials aren't in their place, you are going to lose money or get hurt.

Now, it's on to the karts!!

First thing up:  specifications, conversions and ratios.  We will identify gears, sprockets, pulleys, chain and belts, and talk about how we can use these to change the strength and speed of a vehicle.  We will also talk about some basic conversion:  wheel size to rpm is up first!  These topics are based on some excellent curriculum from VEX robotics, see Unit 8 on Mechanical Power
