Magnetism: What will you attract?

There are so many things that we don’t know. If we started to list the things we don’t understand it would take a loooong time. There’s that comedy skit where a man goes back in time and thinks, “Great, I’ll impress everyone…”

“In the future,” he says, “we have fridges that keep food cold, toasters that make bread hot and air conditioners that make the air both hot and cold.”

“WOW, how do they work?” is the response.

“Well, you just plug it into the wall and press a button. We have cars, trains and airplanes that transport us round the world.”

“Wow, how do they work?” his audience wants to know.

“Well, you just put the key in and press a button.”

So, do you need to understand the science behind magnets to enjoy playing with them? I don’t think so. Isn’t it enough to work out the properties of magnets? Start to develop the language connected to the topic. Investigate the phenomenon with the children and enjoy the wonders of magnetism.

Here are some ideas you may find attractive

Use a magnet to test what substances are magnetic or non-magnetic. Any substance which is attracted by a magnet is called a magnetic substance. Introduce some keywords, by talking about the magnets’ poles and describing how they attract or repel each other while playing with various magnets and seeing what ‘works’.

Why not collect things that are magnetic and the things that aren’t? You could make a display – a museum of magnetism. Are all metals magnetic substances? Actually, all magnetic substances are metals but not all metals are magnetic. Try aluminium or gold. In fact, most of the magnetic substances you find will be iron or contain iron. That’s another good question to investigate with children – What makes a metal a metal?
