magnets and electricity power point
TRANSCRIPT
Let’s take a FIELD TRIP on the MAGIC SCHOOL BUS!
For today’s trip Miss B, will take you through magnets and electricity!
SO…
What have we learned about
magnets that can be useful in our
adventure?
What do magnets attract?WOOD?
Paperclips?
IRON NAILS?
Other magnets?
Plastic?
Pennies?
G l a s s ? O r a fl o w e r ?
You are Correct!
OH NO!!! Our bus broke down!
What Magnet strength do you think we need to get our bus across this bridge?
OR
Magnetic poles
Where is our bus headed now?We’re headed to
the north, our magnet is pulling to the North pole
Magnetic ForceOur bus is SO slow, we are never going to get to the North pole in time.
BUT…
We can make our bus into a big magnet, that way we can use the EARTH’s natural magnetic field to help pull the bus closer to the North Pole!
Let’s go into the smallest part of the
magnet
ATOMS
They have protons, neutrons, and
electrons
ELECTRONSElectrons are attracted to protons, like – is attracted to +.
This is how magnets work with each other.
Let’s find some natural magnetsThere are rocks that are magnetic called magnetite, which mother earth
makes herself!
Now we know about magnets, Where are they used?
On Through Electricitiy!
Let’s head back home and become electric! Now…. What have we learned about electricity?
Electricity
It’s a flow of electric charge
POSITIVE(+) AND NEGATIVE(-)
ATTRACTIONS
Just like Magnets
WHERE IS ELECTRICITY USED?
Let’s flow with electricity that is in
lights to learn more!
Electricity Safety.
Do not touch light sockets!
Do not use electricity
around water!
Electric Circuit
Oh no! Our bus stopped moving
through the circuit! Why? Let’s think of
ways to fix it!
Yay! We fixed it by connecting the circuit
Electricity Discovered!
Benjamin Franklin
Who is this?
In 1750, Franklin flew a kite that was hit by lightning
Kite with key
Electricity sources.
Power from the sun.
Power from the wind.
From the moving water.
From many different power plants.
From batteries.
WOW! Why is her hair like that?
BALLOONS, WHEN RUBBED AGAINST
SOMETHING CREATE SMALL STATIC ELECTRICITY.
TRY THIS!
Rubbing a balloon against your head
Drag your feet with socks on the carpet and quickly touch something like a door knob or a friend.
IT’S FUN!
WHEW! We made it back just in time for lunch!
Remember to share our field trip with your parents. These websites may
