MALANGENNA CHILDREN’S CENTRE, Chemical Reactions
Malangenna Children’s Centre investigated chemical reactions with a bang!
From rockets whizzing to volcanos exploding, Malangenna Children’s Centre child led investigations were a blast.

What we said…
We pictured bottles whizzing all over the centre. Building on the children’s interests the centre investigated what made bottle rockets fly.
The children’s ideas were taken into account and they tested their own hypotheses. Repetition is important in science experiments and we can imagine that the rocket experiment is one that will be repeated again and again.
In their own words…
Our project connects to other experiments that we have been doing with bicarb of soda and vinegar. We’ve been experimenting with these ingredients for some time now.
This project is about building a rocket using these active ingredients. The educators asked the children if they would like to research on the internet to find an experiment that involves the use of bicarb and vinegar. We came across a science experiment that involves a bottle, pencils, duct tape, cork, bicarb, vinegar and paper towel (bottle rocket).
We gathered all the resources and ingredients and discussed how we were going to build it, that we needed the pencils to make the rocket stable and the tape to secure the pencils to the bottle. We stood the bottle upright on the pencils to ensure that the bottle (rocket) would stand up and placed all of the ingredients in front of us.
The children measured out how much vinegar they thought they would need and poured it into the bottle. We discussed the mathematics involved, the distance the rocket would fly, the volume of vinegar and how much bicarb they could use.
