Today we shared our presentations on important discoveries with our class and some of our parents who came along to be part of our audience. We were asked to share an important scientific discovery and have spent the last two weeks researching, planning and organising our information.
We presented on a lot of different discoveries including electricity, gravity, sound (and the telephone), New Zealand, the Great Barrier Reef, Samoa and the atom.
We gave each other feedback on our presentations and next week we will reflect on what we can improve on.
Keep checking back to see some of our presentations here on our blog soon!
On Tuesday our class connected with our pen pals from Korumburra. We have written letters to them before but this week we spoke to them face to face using Skype! It was so much fun to see them!
We played Guess My Number first as a whole class (they won). Then we spoke to our pen pals in groups of 3 or 4. We asked lots of questions and found out about what games they played, football teams they follow and even about some pets! While we were talking with our pen pals, the rest of our class were working in the classroom.
We are waiting for the letters they sent us last week so we can reply. We will also be video calling them regularly next term so we can get to know each other better.
Over week 7, 8 and 9 we have been growing sprouts. We didn’t just use water but we used other drinks as well such as Sprite, Coke, orange juice and milk. The sprouts with water grew while the rest started to grow mould! You can try this at home. All you need are sprout seeds, soil, drink of choice and sunlight.
Let us know if your sprout grew!

This term we did the colour magic experiment and the dancing sultana experiment. First we wrote a hypothesis and then the materials we needed. Then we did the experiments. After the experiments we wrote our observations.
How the colour magic experiment works is you put some M&Ms or Skittles in a petrie dish (or small dish) and cover with water. Then you put a sugar cube in the middle of the dish. The colours dissolve off the lollies and do not mix together. When the sugar cube is added, the colour is pushed away from the middle of the dish by the larger amount of sugar.
What you do for the dancing sultana experiment is you put vinegar in a plastic cup and pour a little bit of bicarb soda in it. It may fizz! You then put objects in the vinegar and see if they dance. We found that flat objects like paper clips sink and bumpy items like sultanas dance and move with the bubbles.
We have been reading ‘Fish In A Tree’ by Lynda Mullaly Hunt this semester and we finished it last week!
We discussed lots of reading strategies as we were reading the book. We thought about predicting, questioning, connections, inferring, synthesising, summarising, finding out meaning of vocabulary we didn’t know and many more. We also identified character traits of the main characters and spoke about their choices and how this affected them.
When we had finished reading ‘Fish In A Tree’, we spoke about the message that Lynda Mullaly Hunt might have been trying to share with the reader. We included our ideas in a book review we share wrote. A book review is a summary of the book that also includes our personal opinion. Please read our review – Fish In A Tree Review by 4D.
Have you read ‘Fish In A Tree’ before? We highly recommend it! Would you read the book after reading our review? Let us know in the comments!
Today we did an experiment called Colour Magic. We were chemical scientists and looked for different reactions between things.
We chose different lollies – Skittles, M&Ms or Smarties – and then we mixed them with different liquids to see what the reaction was. We could put the lollies in either water or vinegar.
Our teams chose what lollies and liquid they were going to use. We have one area the same and one was different. For example, one team placed skittles in water and skittles in vinegar.
We followed the scientific method and made a hypothesis about what reactions we would be observing. Then we observed as we completed the experiment.
Here are some pictures of our experiments in action:
We observed some similarities and differences between the vinegar, water and how the colours on the lollies reacted. The colours all dissolved off the lollies in both liquids but the brightness of the colours was different between the Skittles, M&Ms and Smarties.
Have a try of this at home and let us know of any different reactions you see!
This term our Student Leaders were presented with Certificates of Congratulations from our local State Government representative. Thank you to Ros Spence MP for recognising our excellent Student Leaders of Aitken Creek Primary this year.
Our Student Leader Group has been very busy this year so far – taking on the role of Peer Mediators during break times, hosting school assemblies, assisting with organising school wide events, writing and hosting our school Anzac Day assembly as well as attending both our local Craigieburn Anzac service and the the Melbourne school service at the Shrine.
We are looking forward to these leaders taking on more roles like these as the year continues.
In week 4 we were lucky to Skype with a real life scientist! His name was James. James is a biochemist. We discovered that a biochemist is someone who studies chemical reactions and processes of living things. James studies allergies in particular.
After we found out what type of scientist James was and what he studied, we brainstormed a list of questions we could ask him. Here is our list of questions we hoped could be answered:
How old were you when you became interested in science?
Why did you want to become a biochemist?
Did you want to be something else instead of a biochemist?
How did you become a scientist?
How many years were you in university?
How many years have you been a biochemist?
What interested you about allergies?
Do you work with a mate (friend)?
How many people work in your lab?
Do you have a lab? What does your lab look like?
Do you use chemicals in your work?
Do you have a boss?
Do you have time to hang out with friends or do you work all the time?
Do you enjoy being a scientist?
How many things do you know about science?
How do people have allergies? Why do people have allergies to different things?
How do you figure out people’s allergies?
Why is Spring the most common season for hay fever?
What is anaphylaxis?
Why do milk allergies (or any allergies) go away when people get older?
Why does America have the most percent of allergies?
How many people have allergies?
Can allergies pass from one person to another?
As you can see, we had a LOT of questions!
When we Skyped James it was very cool! He answered as many of our questions as he could. We listened to a lot of information that day!
Have you ever Skyped a scientist or spoken to another expert in something? What did you learn?
We found a MASSIVE leaf outside our classroom. One of our classmates wondered if this was the biggest leaf we could ever see – it was very big!
We discovered that it was not the largest leaf in the world. The largest leaf in the world comes from the Raphia regalis (Raffia Palm). The leaves from this palm can grow as large as 25 metres long and 3 metres wide! The Raphia Regalis can be found in Angola, the Republic of the Congo, Gabon, Cameroon, and Nigeria.
Have you ever discovered something and learned more about it? Let us know!
Congratulations to our classmate who was presented with her gold medal from MangaHigh this week! She earned so many points during the Maths Ninja Competition last term that she received a real gold medal! Well done and a fantastic effort!
Our Big Idea for Challenge Based Learning this term is ‘Discovery’. One of our provocations to start us thinking about this idea was to draw a scientist using our prior knowledge. Provocations are prompts about a topic or idea.
We had some great thoughts about what a scientist does and what they work on. Have a look at our work below:
How would you answer the provocation prompt: What is a scientist?
