Last week we started looking at Chemical reactions, and what can make them. We looked at the 'fizz inflater' video on the Year 3-4 Science wiki.
Today, the children of Room 8 taught Miss. Collier how to conduct this experiment by giving her step by step instructions.
Photographer: Alex Brown Room 8
The experiment shows that an acid (vinegar) and a carbonate (baking soda) can make a gas (carbon dioxide) when mixed. It blows the balloon up.
After the experiment we discussed what would happen if...?
- there was more vinegar
- a bigger bottle
- we used a water balloon etc
This week Room 8 will be working in groups to modify (change) the experiement by changing the...
-amount of vinegar
-amount of baking soda
-size of bottle
-size of ballon
The children will need to predict what will happen (hypothesis) and plan (equipment, ingredients, method) before conducting their experiment. They will then need to observe (watch) and record their findings (results).
Keep checking the blog to view updates of our experiments!

WOW Room 8!
What fantastic scientists you are! I loved watching the video of you teaching Miss Collier how to make a fizz inflator!
I have shown your blog to some scientists at university and they were really excited about the science you are doing and wished they had had a teacher as cool at teaching science as Miss Collier when they were at school!
I remember doing the fizz inflater it was fun.
I remember the fizz inflater. It was fun!

awesume blog, really liked the fizz inflater, great stuff Lachlan and the rest of room 8, you all rock
I loved doing the Fizz Inflator experiment. I want to do it again at home. It was really fun. I learnt that an acid and a carbonate makes lots of fizz. Thanks for teaching us science. From Isla!!!!!!!!
