Why do our muscles get tired?

WALT use our reading strategies to find information in the text.
I learnt about muscles fatigue and how you get it.
You get muscle fatigue if your muscles are not getting enough oxygen and energy to them fast enough. I enjoyed learning about muscles fatigue and how you can avoid it.
I found understanding some words tricky and interesting.
My group found some of the vocabulary tricky but our teacher helped us figure it out.
I can do some vocabulary better.

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!!!

Matariki

We are  learning all about Matariki.

We have been learning about Matariki and how Matariki was so important in the olden days. Something that interested me about Matariki was that they made kites instead of making a cake.   

I found that they did not use fireworks to celebrate was interesting.It surprised me that there are five hundred  Matariki stars, but only seven can be seen with the naked eye. I enjoyed learning about Matariki and what they did to celebrate it.                        

I found reading some Maori words tricky to  read. I  did my scratch project really well and I can do some more code for my avatars.
