At Follett Street Kindergarten this term, mat times have included learning about water - such as what makes it rise and what makes it fall.
Two books were read to help discuss how the water in a bath was affected by the amount of people getting in, or out, of the bath. Teacher Tracy explained to the children that as our bodies take up space, the more bodies that are in the bath, the less space the water has to go, therefore making it raise higher.
At the end of the second book, Louise brought out a large 3 litre drink bottle with a bit of water in it. Using lots of stones to make the water become higher in the bottle, provided a different visual aspect to help the children understand and embed their new knowledge.
The children swapped the stones for lighter items too. Noticing that these just floated encouraged a new discussion about weights. Water and weights are a great way to help children develop working theories for making sense of the natural, physical and material worlds. They were interested and engaged and continued their learning outside in the water trough using containers.
