Changing shape: review
Lesson details
Learning outcome
I can find out how the shapes of solid objects made from some materials can be changed.
Key learning points
- Squashing, bending, twisting and stretching are ways in which some shapes of objects can be changed.
- The results of a test can show what happens when objects are squashed, bent, twisted and stretched.
- Some objects are made from materials whose shape cannot be changed when squashed, bent, twisted or stretched.
- Some materials do not change back to their original shape on their own after being squashed, bent, twisted or stretched.
Keywords
Material - A material is what an object is made from. An object can be made from more than one material.
Change - If something changes it does not stay the same.
Shape - A shape is the outline or form of something.
Results - The results of a test are what happened or what was found out.
Original - When something is original, it is the first one.
Common misconception
Pupils may think that all objects that can be squashed, bent, twisted or stretched will return to their previous shape.
Opportunities to explore the impact of squashing, bending, twisting and stretching different materials.
Teacher tip
This lesson follows on from lesson 6 of this unit. The pupils will use the results and investigate further to find out if the objects can change back to their original shape. This lesson contains a diagnostic question on slides 18 & 19 - see additional materials for further guidance.
Equipment
Different materials to test, e.g. a rock, a sponge, a sock, dough, paper, a rubber glove. Ensure you have a variety of materials, including some that keep their new shape after being tested.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
