Warm up: materials and properties
Before the big design challenge, let's warm up what you know about materials and their properties. This is practice — it is not marked.
Practice questions
Q1. Match each material to the property that best describes it.
| Material | Property |

Property words: strong • soft and cushioning • transparent • light and fluffy
Q2. For the egg-drop, which property is most useful for cushioning the landing? Circle it.

Q3. Why might tape be useful in your design? Think about what property it has.
Q4. Plan ahead: name two materials you might use in your egg-drop design, and the property that makes each a good choice.
