Jess and Susan’s Class: Term 3 Week 8
Dear parents,
This week we’ve had a deep dive into the three (oops…four) states of matter (solid, liquid and gas… and plasma!) We explored how water particles behave when moving between the three states, and the effect of adding or removing heat on these particles.
Our first experiment looked at the relationship between the viscosity of a substance and the speed at which it freezes. Our second experiment explored what happens when a liquid and solid are combined to make a gas.
The children have asked some fabulous questions about atoms, molecules and even the nature of the universe. What existed before the big bang? Is a particle alive? Why does milk go yellow when it freezes? And so much more….
We’ve also been focussing on the relationship between English and Science and the importance of scientists having strong writing skills to communicate their ideas and discoveries. We have written up our experiments using appropriate subheadings, including Aim, Materials, Method, Results and a Conclusion.
This led to a fabulous conversation about the nature of collective human knowledge and the process of scientists building on the discoveries of those that came before them.
After our PIP session on Thursday, we packed our backpacks and headed off to explore pockets of bushland in our local area. Along the way, we observed the shape of the land, watercourses, evidence of weathering and erosion, and some of the methods used to help control erosion. We also discussed where stormwater goes after it enters our drains and how rubbish and other pollutants can be carried into our local creek systems.
When we reached Gore Creek Reserve, we observed tree roots growing into the cliff face and identified layers of shale and sandstone. We crushed pieces of shale in our hands and discussed how the softer shale weathers more quickly than the harder sandstone, noticing the depth differences in the cliff face.
After a well-earned play at the playground, we began our journey back to school via Lillypilly Falls. A highlight was travelling through the tunnel under River Road – after first having an important discussion about safety around stormwater drains and pipes – and then taking the bushland route home via Kelly’s Flat.
The children did so well on a very long walk! There were one or two conversations along the way about how we can reframe something that feels challenging by focusing on the positive benefits – being outdoors, building our fitness and resilience, exploring new places, and enjoying the satisfaction of completing something difficult.
Special thanks to Vicky for coming along and helping to make this adventure possible!
The rest of the term is very full, with a lot of content still to be covered. so, although I know everyone is tired, please hang in there and try to schedule some early bedtimes!
Warm wishes
Jess and Susan
