In Math this week, we began our new unit on measurement. There was lots of enthusiasm about the concept of measuring with non-standard units. We discussed things we could use to measure - shoes, hands, a long piece of hair... And when someone suggested that we could use people, we just HAD to put that to the test. We decided to see how many people it would take, laying end to end, to make it from one end of the room to the other. The answer, for curious minds, was 7. But!...how would this change if we used grown-ups to go from one end to the other? What about babies? While we were at Hoffman Park yesterday we each got to choose a special stick to bring back with us, and today we got to use them as measuring tools. We took them outside to measure the slide, the monkey bars, and a whole host of other interesting things on the playground. In the end, we've realized that in order to measure something in a way that we can describe to other people, we need to use objects whose size doesn't change. We tried measuring a list of things in our classroom using standard unifix cubes and paperclips. In Science this week, we felt pretty special because we got to use TEST TUBES! (Everyone knows only "real" scientists use test tubes.) We filled the tubes with different coloured water and put flowers in each of them. Our hypothesis is that the colour of the flower petals will change, depending on where the stems have been placed. We are now anxiously waiting to see the results. Some of the flowers have already begun to turn turquoise and blue. Our trip to Hoffman Park was extra special this week because Mme Van Sickle gave us the green light to climb trees. With some strict safety rules in place, we enjoyed testing our limits. We finished off our Friday with a blast from the past (hello 1980s!) toy from Mme Van Sickle... a pogo ball! Why have these things gone out of style?! They are ridiculously fun!
