To finish up our unit on Ancient Rome, Grace created an Ancient Roman water clock (kind of). She also worked to solve the “murder” case of Marc Antony, but that didn’t lend itself well to blogging…we’re going to focus on the water clock instead.
In the Roman Senate, speakers were only allowed to talk for a few minutes (no long-winded speeches…nice!), and the time was measured with a water clock.
To make our water clock, we used two cups, craft sticks, binder clips, a push pin, and water. It was all pretty simple, actually.
Checking out the supplies.
We used binder clips to hold stacks of five craft sticks together. We then checked to make sure the sticks would support a cup properly. (You could use anything to lay across the top cup, really. It just needs to lift the top cup off of the bottom one.)
Then we used our push pin to make a small hole in the bottom of the top cup. (It turned out that this hole was a little too small, so we used our pin to make it just a little bigger.)
Here’s where we started really having fun. We were aiming to have our water clock measure three minutes. We started by filling the top cup with water and letting it run into the bottom cup for three minutes…this gave us an idea of how much water we would need for accurate timing.
Grace waited patiently as we timed the clock a few times, adjusting the amount of water as needed. We got pretty close to what we were aiming for, and we were content with that. :)
Now that we’re finishing studying Ancient Rome, we’ll be starting next week off with the Vikings. Fun!
