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.
HI Izzi its Ashita. It was really nice of you to bring the volcano kit in and share it with
ReplyDeleteus.I have got one question, why did you wear goggles and gloves?
To be safe, just as a precaution as the chemicals are not dangerous. My dad told me it's good practise.
DeleteWow Izzi. That looks like a great experiment. What do you think the 'lava foam' was made out of? From Mrs Pulman
