Mad Science

 WALT predict and explain what is happening during our science experiments.

Last Friday my class and I did some science. My favourite science experiment was the lava in a cup because it was like a real volcano, we used water, oil and salt to make the amazing effects, the effects were like a real volcano, the salt was dissolving which made the lava like bubbles. My second favourite experiment was the magic milk we had Te Pihi one of the junior classes came to watch us do the magic milk, the ingredients were milk, dish wash soap and food colouring. My last favourite experiment was the crawling colours, the ingredients were water food colouring and paper towel.

Copper complexes: MEL science

Copper complexes

today my sister and I did a science experiment called "copper complexes".  Here are the chemicals we used in this experiment.

1. Sodium Sulphur
2. Sodium Chlorine (table salt solution)
3. Ammonium carbonate
4. Copper Sulphate
5.  three vials 6ml capacity

I am going to tell you a story, a real story about chemistry. It is a story of beautiful colours and reactions. We can't see the reactions, apart from observing the results, but it's chemistry...and it's beautiful.

Yesterday something exiting happened, we did a Mel science experiment.  We learned that you can use one chemical (like Copper Sulphate) to find out unknown chemicals, just by looking at the results. That's what I am going to tell you about.  At first the science experiment was boring because the chemicals were transparent and colourless. But when we  added the copper sulphate each chemical had a unique colour, the first reaction was a urine yellow colour, the second reaction was an ocean green colour and the third reaction was a royal blue colour. The reactions were amazing. Even though science is very complicated I still love exploring it. We were not allowed to taste the chemicals and my dad had to expose of it according to the instructions.

Making sure my sister is doing it right ; )












Can you see the difference???
Neither could we!

 

 

Don't mind me, I'm just adding Copper Sulphate



What!!! It changed colour!!!
