Today was the culmination of 3 weeks' work on probability.
Each student started with an asTTle test on Probability and then they identified their learning pathways. Students signed up for workshops with teachers.
When they were not part of a workshop students worked in groups from across the area to design a game for a Probability Fair. As well as designing the game they had to calculate the probability of customers winning and how much money that probability would make for them.
Today was Fair Day. Each group started with $10 and each person had $5 to spend! The winning group made a profit of $39 - well done Jamie's group! The best individuals won $12.

Today in area 5 we got a look at the new bins that are going to be put in area 5!!! We were talked to by Christien from waste wise about why it is important to use the bins in the right way. She told us that Auckland fills up a Rugby pitch each week with rubbish that is going to the land fill. She also said that if recycling in a truck was contaminated by even just 17% then the whole lot has to get put into landfill.

Today we started working in our new learning inquiry teams. To build some team skills we competed in the marshmallow challenge. The challenge was to build the tallest free standing tower from 10 pieces of spaghetti, 1 marshmallow, 30cm of string and 30cm of tape. We only had 20minutes.

When we first placed the food colouring in the milk, it stayed as a blob. When we added a drop of soap from the toothpick it spread out and were pushed towards the edges of the bowl.We noticed that after the colours began to spread out, gradually the came back in.Once we put the dishwashing liquid in, there was a delayed reaction before the colours began to expand.

How does it work? What makes the food colouring in the milk move? We think that the way it works is that the chemicals in the dish washing liquid reacted with the food colouring chemicals.
Can you relate this to something in your everyday life? This relates to everyday life because it’s like when you do the dishes, when you put the dishwashing liquid into the water the chemicals react and make bubbles.
How could you build on this experiment to make it an interesting science fair topic? You could test it on even more colours and see which one moves the most. You could also try it with different amounts of dishwashing liquid.
When we added soap to the food colors in the milk the colors started to pulse outwards. After 30 seconds the colors expanded then closed in.
When we added the soap closer to the food coloring the area in which it expanded grew a lot larger and the pulsing was bigger and seemed to last longer.
Other things we noticed during this experiment where: The colors blended forming other colors such as purple, When we added the food coloring the circles grew slightly bigger and faded around the sides and sometimes little bubbles would form and float across the top of the milk.
What makes the food coloring move?
We think that it is the chemicals in the soap cause a reaction and the food coloring spread out across the milk, before the food coloring stopped pulsing it spread then compressed.
Can this relate to everyday life?
We cant think of anything in everyday life that involves this science experiment
How can we turn this into a science fair experiment?
To turn this into a science fair experiment we can test what food coloring expands the most and the differences between each of the colors when oil is added.
When we first added the food coloring to the milk the food colouring spread a little but not enough to notice. When we added the dish washing liquid the food colouring spread throughout the milk and moved in a motion. The more dish washing liquid we added the more it would ripple. The closer we put the dish washing liquid the faster the dish washing liquid would react to the food colouring forcing it to move faster. We have seen a variety of colours being mixed together forming other colours. There is a chemical reaction that causes the colours to move. This relates to our every day life as we use dish washing liquid to remove grease from pans. To make this an interesting science fair we could use different milks like soy milk and others to see if we get the same reaction.
