Before Christmas the Gr.2Js were each given a coin (a sinker). They were then asked to use a variety of material to make their sinker float. We tested them today to see how we each did. Some of us had to adjust our designs several times, however everybody’s devices floated in the end. Below is a slideshow of some of our “Floating Sinkers”. It’s tough to see the coin in some devices, but they’re all there!
