We learned a little more today about the incredible world of microscopic organisms (microorganisms – bacteria, viruses, fungi, algae etc). The first forms of life on earth (dating back billions of years), found everywhere on the planet (from deep in the Earth’s crust, to the bottom of the ocean, to the outer atmosphere), incomprehensible in number (thousands of time heavier, when combined together, than all other living things combined), some essential or helpful to human life, some causing illness and disease. We’ve tried taking our own microbiological samples from different places (including Sarafina’s tongue – there are more than 7 billion microorganisms in a typical human mouth apparently!) and we’re going to see what grows in agar-filled petri dishes (pictured below) over the coming days. If we see anything then we’ll make up some slides and have a look under the microscope. Exciting!
We’ve been keeping a careful eye on our science experiments and mould is growing nicely in many of the petri dishes. We’re going to let the experiment run for another week and then write up the results and conclusions.
In the meantime, we’ll learn about bacteria and viruses and other sorts of microorganism. And on Tuesday afternoon, we’ll be working with Josey Scullard to make (sew) our own microorganism cuddly toys from different materials. Cuddly salmonella, basically!
Below, as inspiration, a couple of images of the stunning world of microscopic organisms. If you have any materials at home that you think we might be able to use, please send them in on Monday. Thanks!
In science this week, we’ve studied the idea of scientific classification. Here’s Patrick’s write up of our class attempt at classifying the natural world.
Faith suggested a dotted line between living and non-living because the remains of animals and plants are preserved in fossils. Perhaps wooden objects cross over in the same way. And to complicate things further, we talked about how boundaries between living and non-living may blur as artificial life develops.
We also spent a pleasant half-hour in the nature garden, sketching different organisms and plants and then classifying them into the five animal kingdoms etc. Here are Olivia’s sketches and some photos.
A quick round up of this week’s maths and literacy.
In maths, we recapped addition and subtraction methods and then looked at some interesting problems. Here’s one that no-one in 6CM has yet tackled:
Find a pair of 5-digit numbers using the digits 1, 1, 2, 3, 4, 5, 6, 7, 8 and 9 (i.e. use 1 twice and the other digits once each) that totals exactly 150,000. How close can you get?
Next week we’ll move on to work requiring more reasoning and problem solving, including reasoning about missing digits in calculations (7 + x = 10), investigations into number patterns, writing down methods and providing proofs, and solving word problems of increasing complexity.
In literacy, the children wrote a job application letter. We spent a considerable time looking back at the first drafts of the letter, reflecting on the passages that read well and those that didn’t, and practising editing and redrafting skills. We looked at Temmyyaa’s work as a whole class – we’ll use a different person’s work each week. An important message is that everyone’s writing can be pulled apart and improved and no-one should worry when it is their turn but rather enjoy and be curious about the ways that their writing can be improved. The grammar focus was distinguishing between the active and passive voice.
Other news. 6CM has signed up for a ‘School Run’ programme – details to follow. In essence, we’ll run for ten minutes or so around the Turney playground running track a few times each week!
School photographs next Wednesday morning – and we’re off to meet and listen to an author at Elmgreen School on Wednesday afternoon
Have a good weekend
Have you ever seen Sonny’s stunning graphic art? This year he has begun a retelling of Star Wars: Revenge of the Sith using extraordinary characters based on his pet leopard gecko, Buck.

6CM’s ideas on the values ‘welcome’ and ‘cooperate’ were quite political, reflecting current times.
Welcome: Ignas, Jacob, Nina, Reaiah, Sarafina, Sonny
Welcome means to let people into your life and make them feel safe. When you welcome someone, it makes them feel better.
- America is a country of immigrants and has always been a welcoming land. The Statue of Liberty is a symbol of freedom and welcome
- The German Chancellor, Angela Merkel, has welcomed one million refugees from Syria into Germany to make a new life. She has made them feel safe.
- Rosendale likes to welcome new students, staff and families.
Cooperate: Daisy, Gabriel, Jim, Tanya, Wayne, Zeca
Cooperation is where people work together to create or acheive something or to get a job done.
- The European Union is the biggest cooperating team in the world. It consists of 28 countries that agree and try to work together. Europe is the world’s most successfully managed continent. [If this last point sounds like something an adult might say, it was actually Zeca!]
- Scientists around the world work in teams to find cures for diseases and to build the International Space Station. The Wright brothers worked together to build the first airplane.
- Rosendale works together as a school. We work together in 6CM to complete the challenges that are given to us.
