That's all folks!

Well this the end of a great year! We all move to new classes next year for yet another year of exciting learning.

 Thanks for following us!

Making Ice cream

What could be better than making ice-cream on the last day of the year?! (A Science Experiment of course!)

Here are the instructions - Try this at home over the holidays!

What you need:

300ml cream

2 tbsp castor sugar

1 tsp vanilla essence

2 trays of ice cubes

6 tbsp rock salt

1 medium sized zip-lock zip-lock bag

1 large sized zip-lock bag

Step 1: Place the cream, sugar and vanilla into the medium sized zip-lock bag and combine the ingredients.  Be sure to zip up the bag securely first.

Step 2: Place the ice into the larger zip-lock bag.   

Step 3: Spoon the salt over the top of the ice in the larger zip-lock bag.

Step 4: Place the medium bag containing the cream mixture inside the larger bag on top of the ice and salt and zip up the bag securely.

Step 5: Shake and massage the bag for five to ten minutes or until the mixture becomes the consistency of ice cream. 

Step 6: You might like to wrap the bag in a tea towel or wear oven mitts while you’re shaking as it can get quite cold!  It’s also a good idea to do this part outside as the water can drip out of the bag as the ice begins to melt.

Step 7: Once ready, remove the bag of ice cream and give it a wipe to remove the salt from the outside of the bag.

Step 8: You now have your own home-made ice cream!

What's the Science behind this?

Salt mixed with ice causes the ice to melt. When salt comes into contact with ice, the freezing point of the ice (0°C) is lowered (-21.1°C)  By lowering the temperature at which ice is frozen, we are able to create an environment in which the milk mixture can freeze. The fat particles in the milk smash into each other and make big molecules of ice cream!

By the way…

When sea ice forms, most of the salt is pushed into the ocean water below the ice. Water below sea ice is really salty and is more dense than surrounding ocean water, and so it sinks. In this way, sea ice contributes to the ocean's global "conveyor-belt" circulation.

The Antarctic Circumpolar current has a lot of dense salty water and has a lot to do with ocean currents and weather patterns.

UV Beads

The UV Beads are out again! These tiny beads look white while indoors, but when we took them outside the ultraviolet-sensitive pigment changed to blue, green, orange, purple, red, and yellow!

We have learnt that the sun gives us the light we need to see, even if we can't see it all! UV Beads are a terrific way of showing Ultra Violet light. They are a great reminder that we must wear sunscreen in summer – even on cloudy days.

(These beads will be coming home along with some other cool science experiment ideas on the last day of school)

School Picnic

What a beautiful day for our school picnic today. Not a cloud in the sky!
We headed down to the new playground at Grasslees Reserve. It's fantastic now that there is a sealed path going down from Victory Cres to the Main Road AND a pedestrian crossing on the Main Road!! Yahoo! We have been lobbying for a crossing for many years!

A great day at the park and the pool. Tired kids and teachers tonight!

Helpers!

We have had some terrific helpers in Room 4 this year.
Many thanks to Ollie, Miss Kadhim, and of course Daile! You guys are awesome!

Candy Cane Experiment

A Christmas Science Experiment for the final Discovery Session of 2014!

We placed a candy cane in cold, warm and hot water and watched what happened. A lot of our ideas about what would happen turned out to be correct. Great discussions! We were all amazed at how fast the candy cane dissolved though.

We also tried some vinegar and baking soda - water was much more efficient!

Which Paper Towel is the best?

We had 5 different brands of paper towel and wanted to know

• Which could hold the most liquid
• which would soak up the most, 
• which would be the most useful

Each writing group came up with different ways to run their investigation. They decided that the same amount of water had to be poured at the same time to see the results must accurately. Also, they decided to colour the water blue so it was easier to see.

All came up with the same answers. The paper towel that was the thickest and bumpiest was the most useful to have around the house.

Christmas Kindness Advent Calendars

We have come up with ways to do random acts of kindness building up to Christmas - they are all on our hand-made advent calendars. A few days late in starting, but we will catch up!
