Mentos and Diet Coke eruption

Today Room 1 and 5 did a science experiment together. We put 4 mentos pieces into a bottle of diet coke. As the mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide. The diet coke erupted like a volcano.

My it used to be green once review

It Used To Be Green Once

By patrica Grace

 

This text is about a girl and how she thought that her mother always wanted to shame her and her siblings.

This text is a non fiction which means that this text happened in real life. The text starts of as how we find out that their mother likes to save her money. Like how she will cut up old swimming togs and how their father would go to town and get the over ripped fruit their mum would scoop out the rotten bits and then give the holey fruit to them to eat. I enjoyed this text because it is pretty realtable like how they have 14 kids and my mum has 9. I also think that their mum was selfless and she cared more about her friend and relations then herself like she will alwaysgo out on wednesday and would buy everyone things that they needed. I think that this text would be popular with both girls and boys they should be atleast 10-15.
