Having done some of the basic experiments as part of the lesson pack following Archimedes and the door of science (book here) the children have also made the water clock, which is pretty simple to do. You need to make sure the pin holes in the paper cups are big enough for the water to drip though or time will stand still!
From there they have been learning about Archimedes experiments with number patterns. So we have been making triangle and square numbers and then cube and pyramid numbers. It was a good excuse to get out the bead material and the thousand cube box. 
It’s a lovely way to see and present some mathematical concepts.
The children seem to get more out of the lessons when they can stop writing for a bit and make something.
Heleyna tends to join in with those bits as well, so she’s getting a bit of an introduction via the work her older siblings are doing.
Much fun was had.
