Kia ora,
Last week we were doing science. we were using yeast sugar and a balloon, We also used a bottle. Then we poured 3 teaspoons of sugar, 3 teaspoons of yeast and then we poured hot water to a certain level and then we put the balloon onto the top of the bottle.
One thing enjoyed about this activity was looking how big the balloon got. My least favourite thing was the smell of the balloon.
I hope you enjoy my presentation.
