【From Teacher’s Eye ～授業後の先生から一言～】
Is there a party going on at Hop!? What are all those balloons for? This week we experimented with baking soda, vinegar and balloons.
What happens when you add baking soda to vinegar? We’ve seen it before in our experiment with colours, haven’t we? What a fizzy, foamy, colourful week!
This week we took not one balloon, but three balloons (don’t forget to add the ‘s’ when it’s plural!), three bottles, two spoons, a funnel some vinegar and baking soda.
Putting baking soda in each balloon with the help of our funnel and pouring vinegar in each bottle our experiment was not finished.
”What’s next?”
This next part was a bit tricky, because you need two hands to stretch the balloon and place it over the opening of the bottle. Since no one has three hands we needed a second person to hold the bottle.
”(Can you) hold the bottle.”
”Ok!”
Our experiment had not yet come to an end. It was time to lift up the balloons and let the baking soda fall into the vinegar. Immediately we heard great fizzing.
”Sounds like rain.” One student noted.
And as the mixture was fizzing and bubbling it blew up our balloons, some bigger than others!
Having learnt ‘long, longer, longest’ and ‘big, bigger, biggest’ shortly before, I could ask them: ”Which one is the biggest?”
”This one!”
Who would have thought you could blow up a balloon with vinegar and baking soda, but unless you like a sour smell hanging around your house, I would not recommend this method for your next party.
