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?
We were very lucky to have Martin Heppel from “The Resilience Project” visit us today.
Martin spoke to us about gratitude. He told us about two young people he knew who were the happiest people, yet they did not have what many of us take for granted. One boy, Jeremy, could not eat or drink and moved around mainly in a wheelchair, yet he had the greatest sense of humour and was always looking for the positive side of things. The other boy live in Nepal and thought that he was incredibly lucky to be able to go to school even though he only got to go for 2 hours a day and there were no pencils, paper or rubbers at his school.
Martin told us about flipping our mood by thinking of the many good things that happen on a daily basis rather than focussing on the (very few) negative.
He believes that four things are integral to everyone’s happiness and these are; laughter, dancing, music and exercise. He also touched on mindfulness and meditation which he suggested we should all try to do more often.
Martin was an inspiration to us all!
