Unit Summary
This unit explores identifying and comparing the suitability of everyday materials like wood, metal, and plastic for specific uses. It examines how solid objects' shapes can change by squashing, bending, twisting, and stretching. The focus is on simple tests, and using data to answer questions.
Lesson Summary
You will learn to find out how the shapes of solid objects made from some materials can be changed.
Key Notes
- 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.
Vocabulary To Learn
- 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 Mistakes To Avoid
- Pupils may think that all objects that can be squashed, bent, twisted or stretched will return to their previous shape.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key 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.
2. Define this scientific word and use it in context. 'material'
A material is what an object is made from. An object can be made from more than one material. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Pupils may think that all objects that can be squashed, bent, twisted or stretched will return to their previous shape. Correction: Opportunities to explore the impact of squashing, bending, twisting and stretching different materials.
