This week we used Venn Diagrams and tables to sort matter and physical and chemical changes. We noticed that when we were sorting physical examples, it was hard for us to have any gases or liquids that were solely gas or liquid as they would usually have to be in a container which would be solid. We have also talked about physical and chemical changes in matter that the children see in their own lives. We explained Physical Change as when matter changes in shape, size, colour or form but is still the same thing (e.g water freezing- it is a different form and will feel and look different but it is still water). We understood Chemical Change as when something new is created that can't be turned back (e.g. a raw egg to a cooked egg or wood burning). Some examples the children said they had experienced were: baking at home, watching fireworks, leaves changing colour as the seasons change, making slime at home, broken lego. It would be great to get some photos or drawings of more changes at home or outside of school. Investigating WaterWe are also wondering what happened in these photos and the students are being encouraged to observe and notice examples of science all around them.
