What makes one material right for the job and another useless? A Year 5 science lesson on properties and changes of materials, ages 9 to 10. The lesson covers: the properties scientists use to describe materials; what really happens when a solid dissolves; separating mixtures by sieving, filtering, evaporating and using a magnet; and the difference between reversible and irreversible changes, with two full investigations, fair-test guidance and a closing quiz. Ready-to-teach PowerPoint, no prep.
