DESIGN PROCESS






Light_Bulb.gifWHAT WE THINK WE KNOW ABOUT FORCES: (our thinking from Nov. 18, 2015)

MAGNETISM:

-magnets stick to some things (e.g. a fridge, a whiteboard, a wall, a pole) = T as long as there is iron or a metal that will be attracted to a magnet

-magnets stick together = T if opposite poles of the magnets are facing one another (N-S)

-magnets won't stick together if they're put together a certain way = T if like poles are facing one another (N-N or S-S)

-magnets won't stick to: a computer, paint, an eraser, a book, cardboard = T (unless they have metals that are attracted to magnets)

-magnets are made of metal = T (like iron but not all metals)

-magnets are made of iron = T (some are)

-magnets float in space = T they may if there is no gravity; if they come across something they are attracted to, like an iron pole, they would stick to that

-metal sticks to metal = F

-there are big and small magnets = T magnets come in all shapes and sizes



GRAVITY:

-if there was no gravity things would float in the air, you would not stay on the ground = T

-gravity is not floating - Gravity stays on the ground = T it helps you stay on the ground - without gravity you wouldn't

-gravity can lift you up = F - things float when there is no gravity

-gravity helps us stay on Earth = T

-there is no gravity in space = F there is a small amount of gravity everywhere in space - it's what keeps the moon in orbit around the Earth

STATIC ELECTRICITY:

-when you put a ballon to your hair it will stick to your hair (caused by static) = T but you usually have to rub the balloon on your hair; if it doesn't stick to your hair it will make your hair stick out

-when you rub a balloon (on your hair/with your hand) it will stick to a wall (caused by static) = T

-when you get a magnet and put it on something electrical and then take another magnet and rub it together your hair will float) = you're thinking of this kind of large metal ball which uses static electricity to make your hair stand on end (not magnetism)



Question.pngWHAT WE WANT TO KNOW ABOUT FORCES:

MAGNETISM:

Magnet.JPG

Where do magnets come from? They are naturally occurring (magnetite/lodestone) or made with metal, heat and electricity

Who discovered/invented magnets? It's thought that the ancient Greeks (people from Greece) discovered magnetic rock (magnetite/lodestone) about 4000 years ago

What is a magnet made of? Iron, steel, etc.

Are magnets made out of metal? Yes, but not all metals.

What is the metal that magnets are made of? Iron, steel, ...

How are magnets made? How do people make magnets? With metal, heat and electricity. See the video above listed under Teacher Resources.

How many magnets are there in the world? Too many to count!

How do magnets stick to: a whiteboard, metal? They are made of the type of metal that a magnet is attracted to. The strength of a magnet depends on its shape (the closer the pokes are to one another the stronger the magnetic field) and material (some magnets are made of materials that are naturally magnetic - magnetite/lodestone;

Why do magnets stick together? They only do if opposite poles are facing one another (N-S). They will repel if like poles (N-N or S-S)

How are magnets used? They have many uses: for fun (in games and activities like the ones in class [magnetic tiles to make art, magnets to drag filings to put a beard on the elf], for organizing things [whiteboard magnets for posting notes, etc.], to hold things closed [fridge and cupboard doors, purses], for day to day uses [in TVs, cell phones, car starters], in hospitals [MRI machines]

What don't magnets stick to? Magnets don't stick to things like paper, rubber, t-shirts and fruits and veggies

What is the biggest magnet in the world? The Earth is the biggest magnet in the world (the inner core is made of solid iron and the outer core is made of liquid iron and nickel; as the liquid iron moves around the solid iron, it creates an electric current causing a magnetic field to form around the planet)


GRAVITY:

Where does gravity come from?

What is gravity?

Do bricks stay on the ground because of gravity? Yes.


STATIC ELECTRICITY:

What is it?

Does static do anything bad/hurtful to you? Yes - shocks can be felt. Lightning is a type of static and it can be deadly to be struck by lightning.

What is it made of?

FORCE

What is pushing? Examples of pushing include: kicking a soccer ball, closing a drawer, ringing a doorbell.

What is pulling? Examples of pulling include: holding the handle of a wagon and walking to make the wagon move, putting your socks on, yanking a loose tooth to pull it out



Painting with Magnets:

October 2013: One of the activities we tried during our exploring with magnets was painting with magnets. Here are the results. The steps that we followed may be found below the photo.

mag3.JPG

Here are the steps that we followed:

First, we put our names and blobs of paint (we used red, blue and yellow) on a paper plate.

Next, we put a magnet underneath the plate and a scrunched up paperclip on top of the plate.

Then, we dragged the paperclip to the paint and moved it around the plate with the magnet to make a design!

We discovered that the force of the magnet was strong enough to attract the paperclip through the paper plate! Some of us accidentally had 2 or 3 plates stacked together and the magnetic force of some of the magnets we used was still strong enough!

(Note: The paper plates are from Dollarama - flimsy but perfect for this activty.)


Students spent an hour on April 12th, 2015 creating a toy/game or activity that uses the force of magnetism or/and gravity. There was a lot of great thinking and problem solving... see below for a video of the results.!




Some of us watched this to get some ideas for our own designs: Caine's Arcade - Imagination

Light_Bulb.gifOUR LEARNING:

- Earth is like a giant magnet (it has a north pole and south pole)

- opposites attract (opposite poles of a magnet attract -- NS or SN)

- likes repel (like poles of a magnet repel -- SS or NN)

- magnets attract some but not all metals (iron, steel, nickel and cobalt are attracted but aluminum and copper are not attracted)

-most magnets are made by humans (in factories/with machines); lodestone is the name of the mineral that is a natural magnet

-the force of magnetism isn't visible but iron shavings/powder on a plastic plate with a magnet underneath help us see what it would look like!
