Izzi's holiday story

Bump! My bottom hit the floor on the roller blading disco rink.It was my first time roller blading.I didn’t know how to get up from the ground on roller blades so my mum had to help me.I went with my mum,my brother Damian and my cousin Emma.Then a man came took my hands and then my brothers hands and took us to the wall of the disco rink were lots of people were.The man showed us what to do and he told us how to get up if we fell.Then my mum looked around and asked “wheres Emma?” Emma was frightened to go on the rink because she didn’t want to fall.She was at the entrance to the rink so then the man helped her and told her what to do.So then she was staying close to the wall like me.Soon I got better and better.Then I tried to track my mum but she was so fast and in the time she did five laps I only did two laps.Also, I did smaller laps so it was easier for me.My brother found it boring so he went on the bouncy castle.While he was on the bouncy castle I was roller blading then my brother asked my mum  “when are we going?” My mum replied by saying“ In ten minutes.” So we did are last minutes of roller blading and then we  went to have a look at the mall and bought some snacks because we were hungry.Also we looked in a few shops then went back to the car and Broom! Broom! We were home.  

Izzi's Volcano experiment

Today Izzi shared with us her volcano kit.

She completed the experiment and we watched the chemical reaction.  As she was doing it, we noticed a few things and we have some questions.

Izzi used bicarbonate of soda, citric acid, food colouring, water and lava foam to create the chemical reaction.

We noticed:

• It looks like foam
• it was fizzy
• it looked like a milk shake
• there was a chemical reaction
• when we crushed up the lava bombs the reaction was much more noticeable (Rico and Jacob thought this was because the liquid had more lava bomb that it was touching so it was able to react with more and this created a bigger reaction, they said that when it was a solid lava bomb it was just reacting with the outside)

We wonder:

• Why do these reactions happen?
• Why was the reaction different both times?
• How does the water help the reaction work?
• Why was the reaction slower?
• What is real lava made out of?

Thanks Izzi, we had fun watching and we now have a lot of things we would like to learn more about.
