At the end of a busy term, we have: finished our seedling experiment; learned about the features of some Australian native birds; modelled how beaks are adapted to the food they eat. The poster of Australian native animals remains to be completed and the Apollo V Rocket is still being constructed. Around the school, the recently captured photo of a black hole is the subject of speculation. We look forward to Easter!
With a couple of sessions in the Science Lab behind them, the children have begun this semester to learn about the Living World. In the very first lesson, I asked the question, "Are you a good noticer?" It's a question Polynesia, the parrot, asked Stubbins, the apprentice naturalist, in The Voyages of Doctor Dolittle. If we are to learn about nature -- about plants and animals -- we must observe them carefully. Many of our big ideas about nature have come from this very important skill. Nature conducts her own experiments and we can learn from the results.-mjp

Let's celebrate the new learning spaces and the children's exuberance building with cardboard.
Many thanks to two dads who recently shared their fascinating STEM careers with the children.
Via video link, David told us about how he started out as an IT engineer connecting computer hardware, then programming firing systems on tanks, before more recently managing an educational software company.
Lester, who qualified as a mechanical engineer, spoke about designing energy efficient air conditioning systems in large buildings.
The children enjoyed his science demonstrations: a piece of paper lifted in the air; a balloon suspended over a fan; a dvd floating on a cushion of air.
Interlocking cardboard boxes made their fun debut in the STEM area. Once the towers were knocked down, a few giraffes were built. After the giraffes lost a few pieces, a cardboard house appeared. After one of its walls was accidentally demolished, an impressive STEM castle took its place. -mjp
See what happened when we built our pop stick truss bridges ...
Here are the children at the Science Festival with Fiona Brell of the Australian Museum. They are reporting on four native animals which are each responding differently to climate change. For more detail and the sound files, click here.
Today, as part of the school's STEM program, Years 3 and 4 attended the Australian Museum's Science Festival. Many thanks to the parents who helped out!
In the first session, depending on their group, the children had the opportunity to: try some hands-on chemistry; understand the impact of climate change on four Aussie animals; learn about Aboriginal bush foods and medicine; code with Scratch.
We then all met in an auditorium to hear Dr Joseph Bevitt talk about how recent research on dinosaur fossils has changed our image of what these amazing creatures were like (hint: ones we might have thought looked like reptiles, in fact looked more like birds!).
In the afternoon, we all explored the Science Expo. Among the many stalls, displays and activities, we could look through microscopes, watch a 3D printer at work, build models, make artificial snow, extract plant DNA, appreciate Aboriginal tools, and watch static electricity being generated.-mjp

A late welcome in this BLOG to the children from Kindergarten who come to STEM for 30 minutes each week.
Early this year, they loved getting to know the snow owl which has become our mascot. They have enjoyed the stories with a science angle. The world of pretend and play captivates the kindies immediately. If there's a hands-on activity -- building or modelling -- all are happily engaged.
Here the children were asked to roll out some plasticine and make a worm. The clay was cold at first and hard to mold. After it had warmed up, some of us tried to make a snail. -mjp

Last year in May, 10 chicks hatched at the school. Some families then took pairs of chicks home to be reared. Today, two of the chicks, now fully grown hens, returned to their place of birth.
With some flapping, scratching and pecking, Sprickle and Sprackle, quickly drew a crowd. Between them, they reportedly lay between 2-4 eggs per day. We are glad they took time off their busy schedule to come and entertain us.
Thanks to Marnie and her family for allowing us to borrow these two fine specimens for the day and to Else for the enclosure.
Many thanks to Marnie's dad for coming in to talk about engineering with the Year 6 STEM classes. He compared the load-bearing structures in a building to the bones in the human skeleton.
Last week, our building challenge was to make a human figure from a set list of materials -- pop sticks, elastic and bricks. Not easy!
This week, we set out with Year 5 to understand some features of modern factories like the assembly line and worker specialisation. We ran "factories" to produce copies of a pop stick figure. Congratulations to the managers and the workers!
This photo was taken earlier in March from a plane making its approach into Florence Airport. Close to 400 years ago, Leonardo da Vinci lived in this town. He would recognise the majestic Duomo and the contours of the land. If he could watch the plane descend towards the runway, he would know that his plans for flying machines had not just been realised but well and truly surpassed in the modern jet plane.
Why do we need to think about Leonardo?
He was arguably the greatest polymath of his age, working at the cutting-edge of science and art. He is a wonderful ambassador for the kind of learning promoted through STEM and STEAM (if we include the arts). We should celebrate his achievements when STEM returns from its sabbatical. -mjp
What makes a city attractive?
What makes Sydney attractive?
Year 5 had some answers: the ocean and beaches; food from different countries; a clean environment -- little pollution; parkland nearby. Then we watched five minutes of a video which made us consider how a city is designed:
Do you agree with the narrator that old cities are often more attractive than new cities?
Last week, I asked a class of 7 year olds how we could find out what the weather was like in Sydney. The heat was coming in through the windows, the sun was obviously shining outside. “Mobile phone?” said the first child to pipe up.
The seductiveness of e-tech means, even at a young age, people ignore or discount their own senses, their own ability to find out first hand, to think for themselves or consult a human being. Some of you may remember the Leunig cartoon which showed a family watching the sun set on television while, through the window, the sun was setting, unwatched.
What’s the difference between tools and technologies? There’s an interesting take on that question here: http://reflexions.typepad.com/files/the-difference-between-tools-and-technologies-090309.pdf
In STEM, the Stage 3 children have been trying to work out which simple tool works best to help them cut pop sticks. This activity is not just about teaching children how to safely work with tools, or even about how to make a model with simple materials; it’s about how tools have shaped the built environment and, in turn, how we think about the world and our capacity to change it. - mjp
We are Filomena (blonde) and Francesca (brunette).
We are the STEM phasmids – interesting specimens of the insect world.
You may ask: if we are Australians, why do we have Italian names?
Well, our parents were Italophiles. We eat gum leaves but sometimes we dream of living in an olive grove.
Those of you who have been studying the living world this term may have had the opportunity to hold us.
But now to the point of our letter: we need your help!
Over the summer holidays, there will be no one to care for us.
If you would like to take either of us home in the next few weeks, then please write a letter addressing it to Filomena or Francesca.
The letter needs to:
The winner will have submitted a letter which is persuasive and covers all the above points.
If you are successful, you will be contacted in the next few weeks to take one of us home.
We learn about the Sun, Earth and Moon system but it's not long before our thoughts turn to ... rockets. The local park provided just enough space for these water-powered rockets to fly. Wind gusts meant finding the right spot and moment for launching.

What is the ideal mix of sand and water to build a sand castle?
P.S. At least one of the chickens hatched at the school has begun laying eggs. Thanks Lorenzo for the news!
It's always exciting to see the bubbles and fog generated when solid carbon dioxide is dropped into hot water. For pics and a video clip, click here.
