Here in 1/2B we like to mix science and poetry. We did a fabulous experiment this week, looking at pH, acids and bases. We created our very own pH indicator using an unlikely kitchen ingredient.... purple cabbage.
We discovered that sour things, like lemon juice and vinegar turn pink or red because they are acidic while bases like bi-carb soda turn blue. We had so much fun we decided to write a poem about it. We hope you like it!

1/2B's Experimental Explosion of Colours
On Monday we did an extravagant experiment!!
A row of little beakers stood lined up like athletes ready to start a race.
We chip chopped the cabbage, the pretty purple cabbage,
And drowned it in scalding, boiling water.
The steam rose and flooded the room with a farty smell.
Pheeewwwwwweeeeee!!!
We poured the deep purple liquid into our expectant beakers...
BAM! It looked so magical!
All of a sudden there were pinks, light pinks and purples like jewels.
They reminded me of awesome crystals.
The pink reminded me of the clouds in a glorious sunset.
The maple syrup turned orange-ish red, then even redder.
There was blue in the bi-carb soda beaker.
Blue like blooming crystals, like duck's feet, like blue bells.
Blue like a baby bluebird or a shiny, blue, berry.
Sudden colours, making my eyes JUMP with excitement!
On Monday afternoon we learnt about acids, neutrals and bases...
But who knew science could be so much glorious FUN!!
