In mind this is a finite state machine. I would want to see an exhaustive
state diagram.
The circuit could be made using nothing but relays.
Or it could be made with a single eprom and some caps.
Or transistors and caps.
Or 74xx logic chips like flip flops.
Or a MCU chip or CPU based
I'd pay to see the mousetrap version, chuck.

Chuck,
I'll be working with the kids again tonight. Hopefully we'll have
time to go in a bit more detail. The 555 is appealing being it can
do many things. We can use it as a timer, we can use it to flash
leds, etc. The kids will only have to learn about the 555, caps and
resistors.

the ability to look at these things as a kid
would look at them. What is simple to me may not be simple to them and vice

Two suggestions.
1) go to radio shack and get an ardunio starter kit. May want to do this
even if you do number two. This is the modern way to do this and you can
show both the schematic for i/o and the program.
2) I can do what you are describing with four or so dpdt relays. One for
each
Forrest,
Time delayed relay, that may be the ticket. Never worked with them
before, but that would be the easiest to explain to 6th 7th grader
with ZERO electrical experience. Going to start some googleing

Last one I bought was from Amazon. The challenge will likely be finding
one at the voltages you're taking about.
Without the time delay relay, you can do everything but the timed reset.

Make something simple with 3 binary timers
(http://www.radioshack.com/nte74ls163a-ic-ttl-binary-counter/55051075.html#q=counterstart=1).
So you would need an oscillator. You can make one with a couple of
cross-coupled transistors or just use a couple of cross-connected
flip-flips.

Another option is 555 IC's, very easy to work with and a million circuits out
there.
