This Chemical Sciences unit investigates the physical changes of materials and how properties change when materials stretch, bend, twist, heat or cool. Students predict how materials will vary and whether they can be returned to their original state.
It consists of 9 lessons of approximately 60-minutes duration, with the opportunity for multi-session student activities.
The sequence of lessons and suggested time frames should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.
A knowledge check for monitoring student understanding of the unit objectives is included and will require an additional lesson.
Teachers are encouraged to collect samples of students’ work throughout the unit to add to a learning portfolio. These can also be used to assess students’ understanding of the unit objectives.
