Lesson Planning
Teaching
- Explore the properties of different kitchen paper and disposable cloths.
- Make predictions about which would be best at mopping up a spillage of water.
- Investigate which papers are the most absorbent by choosing a method and working in a group.
- Understand the different reasons why people may need to use absorbent materials.
Activities
- Create hypotheses and make predictions about the absorbency of different kitchen paper and disposable cloths.
- Investigate which papers are the most absorbent by choosing a method and working in a group.
Investigation
Consider the questions: are all makes of paper as good as each other? Or are some better than others?
Investigate which papers are the most absorbent by laying thin strips of equal length of different materials (including a waterproof strip) in a shallow tray and pouring coloured water onto the edge of the strips.
