Listen: at the recycling centre, a big magnet swings over a pile of rubbish. Some things jump up. Some stay behind. Why do only some things stick?
Today we will test lots of things with our own magnets and sort them: the magnet pulls it, or it does not.
Today we sort in two ways: the magnet pulls it, or it does not.
Watch the object I hold up. Thumbs up if you think the magnet will pull it. Thumbs down if you think it will not. Guesses are the start of the fun, never wrong.
At your table, take one object at a time. Hold the chunky magnet near it. Does it pull? Keep magnets away from mouths. When you have tested, leave the object on the tray ready for sorting.
Now sort. One hoop is for things the magnet pulls. One hoop is for things it does not. Say the reason as you place each one: the magnet pulls it, or it does not.
Look at the hoop where the magnet pulled things. Look carefully and touch gently. Do many of them feel hard and shiny, a bit like a spoon or a nail?
When I say your name, tell the class one thing you notice.
