FIRST Robotics Team 1515 is interested in hosting a 5 day Vex Workshop directed towards middle schoolers. This would occur in our school's Vex room. Being the person who would organize the event, I have several questions.
First, we are thinking of charging $30/day for 4.5 hours. Lunch will be $4. Is this an appropriate price?
Second, and most importantly (this is the bit we are most desperate to work out) 
what do we need to do in terms of insurance? Of course when parents sign their children up, they will need to sign an extensive waiver in addition to a contract which includes a syllabus.
Third, our planned itinerary goes as follows:
Day 1- basic system design, mechanics and building with Vex.
Day 2- programming in EasyC and sensors/electronics
Day 3- challenge introduced. Will be grouped into teams of 3. Much of day will be spent designing their robot
Day 4- building robot, begin programming
Day 5- finish robots and competition with prizes for the winning team (Arduino, probably)
What are your comments on this?
Thanks in Advanced!
