Assembly 2018

Prize giving 2018

On the 12th of December 2018, Saint Patrick's School had their 2018 Prize giving and also our very last school assembly of the year. I received a certificate for Road Patrols and Peer Mediators. I am mostly proud of the award that I received for representing Saint Patrick's School by being the Manaiakalani Ambassador. As well as Prize giving, each class had a Christmas song or item to perform as shown on the pictures below.

Experiment: Colour changing Milk

-saucer (small plate)
- 50 ml of milk
- 2 drops of different colours of food coloring
- squirt of detergent

Our hypothesis is that the colours will break its separation between themselves and will mix together when the detergent is added.  

What had happened:
Our hypothesis was valid because as we applied the 3 unique colours into the milk, it had tension between them. However, when detergent was added it started to break its tension allowing the colours to bleed and blend into each other.

Chemistry Oobleck

Rosary, Soane, Mana experiment Oobleck (Outside)
Oobleck is a mixture of cornstarch and water based on how much pressure is applied to it. When the mixture is handled, it is formed into a ball but when pressure is released it flows into a liquid, like texture. This suspension only contains two ingredients. Here is the method on how to create it.

What we need:
-½ cup of Cornstarch
-1 cup of water
-Measuring cups,
-Mixing tools
-Newspaper to keep area tidy
-Food Colouring (Optional)

What to do:
  1. Place cornstarch into the container
  2. Then add  water with the cornstarch
  3. If necessary and  more water or cornstarch until you gets a mixture that ‘tears’ when you quickly scrape your finger through it and then ‘melts’ back together again.
  4. Knead it and mix it with your fingers and see what happens

Observations: Our first attempt started with a liquidy substance and at first we thought that we had failed the experiment.  But we didn't stop there so then we added more corn starch and a tiny amount of water while we mixed it the substance started to harden making the oobleck harder to mix. We then added food colouring to change the colour from white then to a minty green and blue. Now for the testing we first tried the attempt of pushing the oobleck. It was a successful attempt at making it but then the challenge was to see if is would stay solid in our hands while playing with the texture then would turn liquid when releasing pressure from it.
