Today was our silly science incursion. We learnt a lot of new things for our science education.
It was sticky, it was gooey, it was slime. In our incursion we made slime, we got to take the slime home after we made it. Did you know that nonutoniaviscoelastic fluid means slime?
POP! The rocket shot out of the beaker. We found out that if you mix bi-carb soda and vinegar together, shake it and put a small rocket on top, the rocket will shoot up.
CLICK! The magnets clicked together. It was time to fish for magnets! We were aloud to catch five fish and then we had to move to the next rotation.
SNAP! The magnets snapped together as we built the tunnels to pull the metal through. As we pulled the magnets through we wondered what mak s the metal attract to the magnets.
Drip, drip, drip, how many pencils can you stick through the bag full of water with out it leaking? 1,2,3, we got a lot.
It was so much fun!!😊

This week the reading strategy that we have been focussing on has been summarising. We have been looking at non fiction texts and learning how to take notes to record the main ideas in texts. WE looked at topic sentences and key words and different ways of taking notes.
We watched an interesting film on the Murray river and learnt about how important this river is for many different reasons.
Some of us took notes on our new whiteboard table.
We are learning about all things science this term and today we decided to do an experiment to see what happened when we mixed oil and water. The first experiment was a bit of a disaster because all of the food dye came out of the oil and sank down into the water. It ended black. WE did it a second time and decided not to put colour in with the oil which meant that the separation between the oil and water was more obvious.
WE wrote the experiment up in our Writer’s Notebooks. Looking forward to doing another experiment tomorrow!!
What’s your favourite experiment so far?
On Wednesday we all went to Scienceworks because our Inquiry topic this term is how changes in temperature effect solids, liquids and gases.
We were able to look at the different exhibitions such as Sportworks and Think Ahead. We went to the Planetarium and learnt about the seasons and the night sky (identifying the stars in the Southern Hemisphere).
The highlight for me was the presentation at the Science Stage. Gordon did a few different experiments using liquid nitrogen. When he mixed water with dishwashing liquid the bubbles became frozen. He explained that liquid nitrogen is extremely cold and when it comes into contact with the dishwashing liquid most of the nitrogen disappears, it changes its state, contracts and spreads around.
He put liquid nitrogen into a bottle, then put a balloon on top. The cold air inside mixed with the warm air and caused the balloon to blow up.
When solids (such as a metal ring) were placed in liquid nitrogen it contracted slightly and could fit through the ring but once the ring went back to its normal state, it could not fit through.
A squash ball and blutac nail, placed into liquid nitrogen became so hard and brittle, that they could be smashed by a mallet!
We learnt that when gases cool down, they contract, when they warm up, they expand.
It was fascinating!!
What was your favourite part of the day?
We had an entertaining performance of The Little Mermaid today!
The story was one that we all knew but it was such a great experience for us all having live entertainment with real actors! The costumes were colourful, the music was loud and I really liked the way the actors asked the audience questions to keep us engaged! It was a mesmerising performance!
What did you enjoy most about the performance?
