Matter – Solids, liquids and gases

The purpose of this lesson is for children to learn that matter can be classified as a solid, a liquid or a gas, and the arrangement of the atoms in these three states of matter dictates their behaviour. When we mix substances together, some changes are physical (reversible) and some are chemical (irreversible). When a chemical change happens, you can never get the substances back to what they were. Matter can change from one state to another and the children will learn how to describe the behaviour of the atoms as these changes occur.
The lesson is organised into a starter activity, a teacher demonstration, and Labs A and B and C. Lab C is the whole class, core working scientifically activity.
It is recommended that children work in mixed ability pairs or small groups. Teachers and other supporting colleagues should facilitate learning by circulating around the classroom, extending conversations through questioning, targeting children for assessment, taking photographs for evidence and recording direct quotes from the children which demonstrate understanding for evidence of learning. There are 3 labs in this box. The box comes with Lesson plan, Whole class teaching PowerPoint, Teacher video tutorial and the equipment.
