This morning we set up a table top invitation with different
magnets and a giant wooden picture frame. One little girl sat down with a big
smile on her face and began sticking all the magnets together. She looked at me
and said, “Look, it sticks!” I asked her “Why do you think it sticks together
like that?” She replied, “I don’t know. It’s sticky.” I asked her if it felt
sticky, and she continued by running her finger across the magnet. “It’s not
sticky. I think it’s magic.” I explained to her that it was called a magnet and
magnets stick to things that are made out of certain kinds of medal. She then
stuck magnets onto the rings of my notebook, smiled, and said “That’s medal!”
After we found all the things our magnets would stick to,
the little girl placed one of the magnetic balls onto the large wooden frame we
had on the table. The ball rolled along the frame as if it were on a track.
This brought attention from the other children, and four more children joined our
group. I placed a magnet in the middle of the frame and rolled the ball towards
it. The children seemed very excited by the snapping noise it made and asked
for me to do it again. I asked them “What would happen if I moved the magnet to
the very end?” “You would have to push it real hard!” said one of the children.
We moved magnets at all different distances and decided how hard we would have
to push it in order for it to connect with the other magnet.
I continued our invitation by asking “How can we roll the
ball without touching it?” They thought for a second, took the magnet wand and
pushed it down the frame. To challenge them a little further I asked, “How can
we roll the ball without touching it with our hands or another magnet?” The children sat longer this time looking
around the table for other options. “Hmmm... I don’t know” answered one of the
children. I walked over to the end of the frame and blew on the ball making it
roll. Everyone began to laugh and immediately tried to do the same.
Just then, one of the children lifted up the edge of the
frame resulting in the ball rolling off the frame and onto the floor. “Hey! You
did it too high.” answered another child. They got another ball and tried
again, only this time lifting the frame a little bit. “We did it! We moved it
without our hands!”
Why This Matters:
The children worked together to figure out how to move the ball without using their hands or using another magnet. This took communication, team work, and listening skills. The children learned about science by experimenting with magnets, and measurement was used by determining different speeds and distances.
What We Could Do Next:
I'd like to extend this invitation by providing the children with different surfaces (such as sandpaper, bubble wrap, water, etc.) and try to see if we can still move the ball without our hands. We could also try experimenting with different strength magnets to see how much weight it could hold and record our results.
Do you have any ideas that we could try?
