Today we had a Science carousel and we discovered many new things. It left a new taste in our mouths and some great thoughts in our minds. Ashling
This fun rotation of activities included:
- Just add water
- Just add vinegar
- Turning up the heat
- Skittles and water
1. This was a messy task but lots of fun. We had salt, sugar, sand and coffee. We observed the reactions of the different substances. I learnt that salt can float on water before it dissolves in. Some of the ingredients didn’t mix and combine like others. Some combinations were watery and some were thick. Riley
2. I discovered that flour absorbs vinegar and turns doughy. I thought that the bi-carb soda and vinegar would explode but it only bubbled and fizzed. The powders turned into a liquid. Mia
3. We made sherbet using citric acid, bi-carb soda and icing sugar. When we added more acid it was too sour. When it went in our mouths it was fizzy. This reaction occured when it mixed with saliva. James
4. We used different types of sugars, icing, brown and raw. When we put the sugars in a tray and over the heat they began to bubble. In the bottom of the tray it became gooey. They turned from a solid to a liquid. When it cooled down again, it was like toffee. The brown sugar became darker as it cooked. Jack and Ruby
5. As I had seen this experiment before I knew what to expect. It was a little bit different. The skittles were placed in water and the colours stared to bleed out. The skittles colours didn’t merge. Later we moved the water and made incredible patterns. Madeline
Today as scientists we were able to create a very messy and unusual mixture. We combined cornflour and water to make oobleck. We predicted that it would be gooey or like dough. We thought that by adding lots of water it would be a liquid. We also predicted that it would be floppy or like play dough. There were some very surprising outcomes.
We began by feeling the texture of the soft and powdery cornflour.
Slowly we added water and watched the ingredients dissolve.
As we began to mix it together, the flour disappeared and we had created a very white, soft liquid.
We were able to drip the runny liquid through our fingers.
The more we handled the oobleck the harder it became.
It turned out very different to what we expected. We noticed that it looked like a liquid but when you held the mixture it formed into a ball.
It seemed to go hard the more we played and rolled it around. Although it appeared soft and squishy it was actually drying out and was able to be crushed.
The oobleck looked like a liquid, acted like a liquid but felt like a solid. We love messy Science!
What other experiments do you know that we could try?
We want to learn more about mixing ingredients, changes and reactions!
A visiting expert joined our class today to inspire us in Scientific investigations.
John Pearce helped us to explore ways of observing and classifying everyday objects. We identified and sorted a variety of materials, into solids, liquids and gases.
In a role play exercise we learnt about how molecules change and react to difference variables. We pretended to be a solid mass but as heat was applied we broke apart as liquids and then finally as gases, dispersing around the hall.
It was interesting to see how many different forms sugar can take from cubes, to grains and a soft powder.
It was a sweet way to begin exploring chemical science!
WELCOME to the 2015 school year.

This term we will be exploring Outer Space and Chemical Science. We are endeavoring to answer the question
“How can Scientific innovations inspire the possibility of future inventions?”
So come along and share the journey of our learning as we blast off into 2015 and reach for the STARS.

WHAT DID WE SEE?
Lightning from the Tesla Coil
Robotic faces that mimicked our expressions
Cycle power creating light
Pulleys used in rescue missions
Static electricity that was hair raising
Ball pit designed for raft rescue in a storm
WHAT DO WE THINK?
We use so much energy
You are safest in a house or car when there is lightning
Lightning travels at incredible speeds
The future os science looks amazing
Science will benefit our lives in the future
Magnets and generators can be joined to create energy
Cars of the future will be renewable and small
WHAT DO WE WONDER?
What was the Tesla Coil originally used for?
How can our mind transmit energy to move a ball?
How could we catch and store energy from a lightning storm?
Could lightning storm energy be used to power houses in remote areas?
Why would we need floating cars in the future?
How long did it take to plan, design and construct Scienceworks and the exhibitions?
At the beginning of Inquiry Learning this term we used Hexagonal Thinking to explain what we already knew about Science and Physics concepts. Things we didn’t know about were put into the parking lot and other topics and concepts were linked to show what the students already knew.
As we are now half way through this term, it was time to revisit the Hexagons and see if our thinking and understandings had changed.
It was awesome to see the groups rearranging, questioning and clarifying their ideas.
Many were surprised by what they had learnt and could now explain their new understandings.
LISTEN to the reflections on their learning!
Physics Investigations on PhotoPeach
I really enjoyed learning about gears and pulleys and how they work. It was great working with my partner Gemma. I liked how we presented our work and the style of the mini expo.
I learnt how lightning is formed and the different types of lightning. I enjoyed making a model and learning from other students.
I really enjoyed learning about water turbines and how they work. I enjoyed working with a partner also.
I found it interesting learning about light and batteries. I discovered how to create an electrical circuit. Our topic was interesting and it was great working with a partner. She had a very creative mind.
I think I did well and I liked working with Tully to learn about how solar panels work. He was a great partner to work with and we shared the information and research together. I also learnt about lighthouses and what’s inside them from Adam.
I learnt a lot of information about batteries and circuits. I enjoyed making a model also.
Physics Investigations on PhotoPeach
To learn more about Physics we set up 6 activities. It gave us time to investigate various concepts about Physics and discover by experimenting, making, testing and observing. We were like real scientists. We used different materials to learn about:
- incline planes
- static electricity
I discovered that static electricity can move cans and lift paper.
Making gears was fun because we could experiment with different size gears and make things. Adam created a fantastic car that moved.
I learnt that using water glass and light I could create a rainbow. The light reflected off mirrors also to make different effects. We used small torches to shine through a magnifying glass. The light was bigger and made good effects.
I discovered that rubbing a balloon on wool gave it static electricity. You could then use that energy to move an aluminium can.
Holding the light under a magnifying glass and shining it on the ceiling created a disco ball effect.
We used two pulleys to lift a kilogram weight, which was easier than just pulling it up with one pulley.
Today we discovered that the word science comes from the Latin word “scientia,” meaning knowledge.
It is system of gaining knowledge through observing, testing, experimenting and analysing to describe phenomena.
The different fields of science include:
