Seriously. I'd like to know. Ok, I've had the occasional experiment/demonstration work out. But more often than not...as my boys would say, "FAIL."
Today, in the interest of learning how ancient civilizations measured the passing of time, we tried to make a Greek/Roman water clock. The directions and illustration that Oak Meadow gave me looked so simple. I thought, "Now here's an experiment I can't screw up." We just needed to punch some holes in some cans (we substituted cups, as suggested in another book we have), set them on a ladder, pour the water in the top cup and start timing.
We were excited. Thing 4 poured the water in the top cup.
Thing 3 was manning the stop watch. We watched. Water started shooting out of the hole in the top cup just like it was supposed to do. At this point, for some reason unknown to me, Thing 4 excitedly shouted, "Look! The baby is peeing!"
Then, as quickly as it started, it stopped. Well, it didn't stop exactly. It just slowed to a sad trickle. Instead of shooting into the cup below, the water just dribbled down the bottom of the top cup and landed on the floor.
Those poor Romans and Greeks. What a lame excuse for a clock.
Thing 3 accurately noted, "That is quite possibly the worst science experiment we've ever done." And let me tell you, given our track record with science experiments, that's saying a lot.
