After our tuning in to states of matter we did some research using library books and Epic! to come up with a definition for solids, liquids and gases. Then we created a class poster to summarise our findings. After that we had a go at sorting the items we had explored last week into solid and liquid using a Venn diagram. It was trickier than we first thought as some things we thought might be both and some things such as sand act like a liquid, but there are tiny solids. We developed our thinking skills through discussions about where each item might go as we justified our choices. To explore the states and properties of matter we made some playdough in class. We discussed the states of matter of each ingredient and the concept of change as when they were all mixed together they made a flexible and malleable solid called playdough. We used the playdough to make models of 3D shapes that we have been learning about in Maths. This helped us to understand the concept connection and the line of inquiry ‘matter can be manipulated for everyday uses’. To go further with the concept of form we collected a large selection of different examples of solids from around the classroom. Then we discussed how to sort them. Very quickly we came up with the idea of materials and sorted them into wood, paper, metal, fabric, glass and plastic. But then we realised the many objects were made of two or even three different materials. So we had to make some sub categories and new labels.
