And so the idea of a labyrinth was born. We started off by using a manila file folder that was laying around and converting it into the base of our labyrinth. I wanted M to help me draw it, but he wouldn't budge. So I drew it myself. 
I then proceeded to show how a small LED light lights up when electrical current is applied to the playdough. M played with it a bit and discovered the importance of maintaining proper polarity. Finally, we built a small enclosure with the dough and put a plastic dome on top (since it's an old observatory. Told ya before - watch the movie for details). We then stuck a couple of LED lights into the dough above the entrance and connected the wires.
M even wanted to play with this dough the next day, putting LEDs in, connecting the wires, and testing what happens when you stick an LED into the same piece of dough. We also built a playdough cake with a red LED candle and in the process found out that our resistive dough wasn't resistive enough and we were much better off with a piece of plastic.


This was M's independent discovery. He noticed this one rock that was red (the rest were whitish-grey) and said that it was obviously a Martian rock.

Later on we came across a beautiful spiral path...

... and a long and mysterious-looking infinite sequence with a limit (a tree tunnel). So we ran along its entire length.

We stopped at a small pond with koi fish and frogs and watched them. M wanted to catch fish, but I had to explain that these are not for catching. So he just sat there looking for the largest and the smallest of them for a while.
Another unexpected zomatical (zoologically-mathematical) find was this little lizard that we spotted. I mentioned how both sides of the lizard's body were symmetrical and we talked a bit about this lizard's line of symmetry.

Then we walked around some more just enjoying the gardens. And then it was time to go back to where we started - to another koi pond with a big waterfall. And so we found another one of the clues - the boundary between two states of matter (in this case - solid and liquid).
When the rest of the trekkers all got back, there was a short discussion of the trek and then we all made a right-angle triangle (since I guess none could be found in the arboretum).
How much of this all stuck with M? Ok, the Martian rock and the spirals did, but the rest - I'm not sure. But you know, it's ok. This was our first Math Trek outing and we both loved it. The main idea was to discover all the beautiful things around us and to not be afraid of connecting them with mathematical concepts. Who knew math could be this relaxing!
The next day was M's little friend's birthday. Lots of balloons and new toys to play with. The weather has improved enough and the men were out grilling. Then it was time for a birthday cake and for our drive back.
Here's how it really worked:
