LT 1: I can explain moving and static electrical charges (the behavior of charged objects).
1. Draw a simple series circuit with a light bulb as your load, a battery as your energy source, and include a switch.
 Diagram should include a battery- wire from one battery terminal (-) to the light- light- wire to the switchswitch- wire back to the other battery terminal (+)
2. Explain why your circuit looks the way that it does (Why would it work/ why is this the correct way?).
 The circuit is in one loop because it is a series circuit.
 The parts are connected with wire b/c they are made of metal and are conductors to allow the electric
current to flow.
 The wires must connect both battery terminals in the loop to complete the circuit.
 The switch is included in the circuit to allow someone to open or close the circuit in order to turn the light
off (open circuit), or turn it on (closed circuit).
3. If your light bulb did not light up, what are 3 things you could check to try and solve your problem?
 Make sure the switch is closed.
 Make sure that battery is fresh and has good connections with wires on both terminals.
 Check for an “breaks” in the circuit.
4. What causes static electricity? A buildup of electrical charges. Charges can be built up in a particular object,
such as a balloon or someone’s hair, or charges can just be unevenly distributed in an object such as a doorknob.
5. Why do you get shocked when you touch something that is “charged?” Electrons jump from one energy level to
the next and can jump from one object to another in an effort to try to become more stable/ neutral.
LT 2: I can describe the behavior of magnets.
6. Draw the behavior of magnetic fields of two opposite poles.
 Diagram should show two magnetic fields (north and south) attracting one another.
7. Draw the behavior of magnetic fields of two like poles.
 Diagram should show two magnetic fields (north and north or south and south) repelling one another.
LT 3: I can explain the relationship between electricity and magnetism.
8. Electricity and magnetism are like two sides of the same coin. In other words, electricity and magnetism are two
aspects on one single force- the electromagnetic force. Why do we say this?
 Moving magnetic fields create electric fields and moving electric charges create magnetic fields. You
cannot have electricity without creating an electric field. You cannot have moving magnetic fields
without creating an electric field.
LT 4: I can use knowledge of electromagnetism to solve real life problems.
9. What are some ways that electromagnets are used in everyday life? What are some products that use
electromagnets?
 Speakers
 Telephones
 Computers
 MagLev train
 Door locks
 Moving heavy objects (junkyard)
 Fire doors
 Motors
LT 5: I can describe how the four fundamental forces of the universe affect the matter
around us.
The Four Fundamental Forces of the universe
Force
What it does
An attractive force between all
objects with mass. Also depends
on distance.
How it affects matter around us
 Holds all of us onto Earth
 Holds moon in orbit around Earth
 Holds solar system together
2. ELECTROMAGNETISM
Holds opposite charges/ objects
together, repels like charges/
objects.



Holds molecules together
Helps form chemical bonds
Holds YOU together
3. STRONG NUCLEAR FORCE
Holds nucleus of an atom together
in the nucleus. Since like charges
repel and nucleus is made up of all
protons (+) and neutrons (0), this
force must be VERY strong!

Breaking the strong nuclear force lets
off an extreme amount of energysuch as in atomic bombs and nuclear
reactors.
4. WEAK NUCLEAR FORCE
Holds the quarks of the actual
proton particles and neutron
particles together.

The breakdown of the weak nuclear
force is what is responsible for
radioactive decay of some atoms/
elements.
