Science - Water and Milk

Today we started our Friday Science sessions with two experiments; one with water and one with milk.

We filled up a cup of water and covered it with a piece of plastic. Then turned it upside down and GUESS what, the water did not come out. The students discussed the idea of gravity to help them to understand what was happening. If air could not get in, the water did not come out. As soon as they shook their cups, air got in and gravity does it's thing!

Our second experiment was called 'Magic Milk'. We used milk, food colouring and a stick with diswashing liquid on it. We waved our 'magic wands' and put the stick in the milk to watch an amazing chemical reaction. There were lots of oooooooooo's and ahhhhhhhhhh's while the dishing liquid made the milk swirl and move in all directions.

The students discussed what was happening. The students decided there was something in the milk that made it react with the dishwashing soap. They brainstormed words like protein, calcium and fat. I was so impressed. They were right, when the dishwashing liquid touched the milk, it reacted with the fats. 

The soap molecules from the dishwashing liquid are trying to attach to the fat molecules in the milk which causes movement in the liquid as the molecules in the fat and soap bond together and expel the water and food colouring.

Science - Simple Circuits

Today we had a fabulous science session looking at ELECTRICTY and SIMPLE CIRCUITS using our STEM science kits. 

The students brainstormed everything they knew about electricity. They came up with words like; energy, solar power, hydro power, switches, wires, lights, power source. They learnt which part of the battery and LED light was positive and negative and then we discussed what an electrical circuit looks like.

The students needed the following for their simple circuit;

• playdoh
• battery pack
• wires
• LED (light emitting diode)

Once the students had their equipment they were able to just give it a go. You can see from the photos how much enjoyment they students had.

A huge thank you to Whaea Jacky for making us playdoh for our circuits and going through each kit to make sure we had everything we needed to build our simple circuits. We really appreciate your time.

Level 2 - Fun Friday - Science

It was great to have 12 students at school today as we welcomed in Level 2. 

Our focus today was on our favourite subject, SCIENCE. Today we did two experiments; one with water and one with milk.

The first experiment was called 'walking water'. We used water, food colouring and paper towels to show how water could 'walk' between the cups. The students learnt what a 'hypothesis' was and they made their own hypothesis about what would happen during this experiment. The students decided how many hours it would take for the water to get from one cup to another. It was a lot of fun! 

Our second experiment was called 'Magic Milk'. We used milk, food colouring and a stick with diswashing liquid on it. We waved our 'magic wands' and put the stick in the milk to watch an amazing chemical reaction. There were lots of oooooooooo's and ahhhhhhhhhh's while the dishing liquid made the milk swirl and move in all directions.

The students discussed what was happening and wondered if it would happen if we used water instead of milk. So we used water to see what would happen and it definately did not have the same reaction. The students decided there was something in the milk that made it react with the dishwashing soap. They brainstormed words like protein, calcium and fat. I was so impressed. They were right, when the dishwashing liquid touched the milk, it reacted with the fats. 

The soap molecules from the dishwashing liquid are trying to attach to the fat molecules in the milk which causes movement in the liquid as the molecules in the fat and soap bond together and expel the water and food colouring.

We can hardly wait for next Friday!
