It was absolutely deluging with rain outside, so unfortunately we couldn’t experience water at the lake or the river, as I had originally intended.
So, instead, we experimented with water inside. We first talked about how much water we had on earth, how it was the most important thing on earth and why, how it tasted, smelled and what it looked like.
We then went to talk about how it reacted, first comparing water to our sand marble runs we made last week. What would water do? It would run down. Why? Because of gravity. What did we need to combine the sand in to a stronger shape? We needed water. Water reacts with materials, changing it’s form.
Then we tried two experiments, both to do with the above facts. The first was seeing how water ran downwards, by the scrunching of paper, and using pipettes and coloured water to drop on the paper, see the rivers it makes, and open it up to see the ‘art work’. The fun part was using two different types of paper – normal printing paper, and watercolour paper, to see which held the water the longest. The watercolour paper was by far the strongest!
We then tested how water could change materials, by using cornflour, and making oobleck. Such a successful experiment with the Monday group, I wanted to try it with this group too. And they loved it! 😄
This group, being slightly younger, found it much harder to add the exact amount of water for the right consistency – thus truly experiencing how water changes form!
Some of the students were away this week on holiday and at concerts, so we had a small group. 😄
