Know it! - State of Matter - Year 4

In the 'Know it!' section aimed at Year 4 students, the topic of focus is the states of matter and how certain solids, liquids, and gases can change state. The learning material encourages educators to incorporate retrieval tasks into their teaching strategy. Retrieval tasks are activities that help children recall information they have previously learned. This approach not only strengthens their understanding during the unit but also ensures that they can remember and apply this knowledge after the unit's completion. Such tasks are essential for reinforcing the concepts of how temperature and pressure can cause materials to transition between being solid, liquid, or gaseous.

By revisiting the subject matter through various retrieval activities, students are given the opportunity to reinforce their learning about the properties of matter and the conditions that lead to changes in state. These activities are designed to be integrated at different points in the learning process, allowing children to consistently engage with the core ideas of the topic. This method of learning helps to embed the scientific principles in their memories, making it easier for them to recall and explain processes such as melting, freezing, condensation, and evaporation, which are fundamental to understanding the dynamic nature of matter in different states.
