A paper clip holder. A farm magnet for animals. I feel like space is a good example of magnets. Maybe this is far fetched but atmospheres pull things into them. The refrigerator is made for magnets of course. Magnetized tips for screw drivers.
2. What experiences have you had with magnets in your life?
I have had experiences with magnets being swallowed by cows to get metal out of their stomachs. I grew up on a farm and these were very prevalent. They are also extremely powerful so I would use these same magnets (clean of course) and would stick them to things all around the house. We used to have an old OLD Mac computer with the disks they had before they created floppy disks and I would stick magnets to that and just ruin it. My mother wasn't too happy if you can imagine.
3. What ideas do you have about the science of magnets.
I feel it has some very basic principles and some not so basic principles. Sadly I don't really know either. I think there are ions that are attracted to each other. So there are ions in the magnet itself and ions in the metal they are attracted to. This sounds good but probably isn't right. There is positive and negative attraction also know as attract and repel.
What I learned post-experiment:
Size does not decide the strength of the magnet. What is in the magnet decides the strength. It doesn't matter what is in between the magnet and iron as long as the iron is in within the magnetic field. Only iron can break the magnetic field. Magnetized=electrons are aligned to retain its attraction. Metal things do not stick to magnets. Iron and few other metals stick to magnets.
Content Standard B
Light, Heat, Electricity and Magnetism
Benchmark: Magnets attract and repel each other and certain kinds of other materials.
Learning Goals: Students will be able to distinguish poles of magnets.
Students will be able to understand that North and South are attracted and like poles repel each other.
Learning Performances: Students have different shapes of magnets and will determine which poles are which by how they attract or repel each other.
(bar magnets, cow magnets, fridge magnets, what pole is attracted to iron, etc.)
Students will record their data and explain.
Future lesson would be explaining charges and why poles attract and how magnetic fields affect magnets and their strength.
Research
I learned about poles of magnets and that many things can be made into magnets. They use North and South poles and the North poles are attracted to the South poles. So opposites attract you could say. But I learned that South poles repel other South poles and it's the same with the North poles repelling other North poles. I found that interesting. I used the website http://www.howmagnetswork.com/ to learn this. It is full of great information including the Earth as a magnet and rare Earth magnets along with uses for magnets and electromagnetism. I found this very helpful. I guess a big thing I would like to know is more about the main part of magnetic fields. It talks about electrons be charged and causing motion for a magnetic field and that all sounds extremely confusing. So as a future teacher if I were to use the paper clip as their own magnets trick I feel I would want a succinct way of explaining how that happens. I still don't really understand that. I also would want more information on iron. When we did our experiment was the iron breaking the path of the paper clip because it was a bigger piece of iron? So my question is if i would put the same size paper clip through the path would it break it or attract them both or how would that work?
