S2.8.3 For the adult
Magnetic force through things
Can a magnet pull through paper or water?
What this chapter teaches
The pull of a magnet goes through paper, cloth, water and wood, and it gets weaker as the gap grows. A fair way to compare two magnets is to count the clips each one holds.
Three questions to ask
There is no one right wording. Listen for the idea.
- What do you think happens when paper is between a magnet and a clip?
- How would you test which of two magnets is stronger?
- Why might a thick pile of cloth stop the pull?
After the chapter, the learner can
- Test if a magnet works through paper, cloth, water and wood
- Compare magnets by counting the pins or clips each one holds
What they copy into their notebook
The pull of a magnet goes through paper, cloth, water and wood. It gets weaker as the gap grows. A stronger magnet holds more clips. Count the clips to compare.
