We finished two weeks of countless science experiments today and what a brilliantly engaging fortnight it has been. The children study Science two/three times per week every week, but this unit got us all working together, talking, hypothesising, laughing and and making a mess while wearing goggles. What more could you want?!
We ended the unit with a red cabbage experiment. Red cabbage juice contains a natural ph indicator.
We poured hot water over red cabbage to extract the colour.
We kept one glass as the 'control' colour and added different ingredients to the other glasses to test their ph against our chart.
Look at Monkey Girl's face! This was the first one we did and the bicarbonate of soda turned the cabbage juice a lovely green.
We also tested others ingredients including washing up liquid, salt, vinegar, soap and ketchup to name a few.
And we had a go at re-neutralising the juice with bicarb after adding vinegar.
We made some great colours!
Soaking coffee filter paper in leftover juice to make our own ph papers for later.
After lunch The Boy did some crazy jumping about according to which letter card he picked up: d is for Dance! and g is for Grab a star!
We worked our little socks off all afternoon.
The two eldest girls finished their week with two sessions of Ballet and I'm finishing mine right now with a night out with a friend. Happy Friday Evening!
Advent next! Watch this space!
