Our pūtaiao (science) focus this week was on Hot Air Balloons.
We completed two experiments showing how gas inflates a balloon.
The first one we tried shows how hot water heats air in a bottle which rises to inflate a balloon.

And the second was using baking soda and vinegar.
A few of our experiments did not work out how we expected. We discussed this and talked about what we could do again to make them successful.
