This fully ready-to-use cover lesson worksheet, adapted from my popular Stretching and Squashing resource, is ideal for unexpected staff absences and allows KS3 students to develop their understanding of how forces deform objects and how Hooke’s Law describes the extension of a spring. Designed for independent learning, it minimises classroom disruption and requires minimal teacher input. With clear explanations, engaging tasks, and detailed answer sheets, the resource supports non-specialist or cover teachers. It's also fully editable, so you can easily adapt it to suit your students’ needs—saving you valuable planning time. 
 
This is the 2nd in a series of lessons and covers the content from the AQA KS3 3.1.3 Contact forces topic and the Activate 2 (OUP) 1b: Forces, 1.3.2 Squashing and stretching lesson.
 
While primarily designed for UK students with British English spellings and vocabulary, the core content and activities can be easily adapted to suit the needs of students in other countries with similar educational systems.
