How did your experiment contribute to your understanding of resistance?

# data[].attributes.body
Can you see what the equation R = V / I tells you about Resistance?

# data[].attributes.body
How did you use your knowledge of electricity to create your project?

What did you learn through the process?

What is a parallel circuit?

How does current behave in a parallel circuit?

How does voltage remain constant in a parallel circuit?

# data[].attributes.body
How does the flow of water in a pipe relate to the flow of charge in a circuit?

# data[].attributes.body
What is a series circuit?

How does current behave in a series circuit (constant)?

How is voltage divided in a series circuit?

# data[].attributes.body
How does voltage affect the amount of work electricity can do? *Remember work is a way of saying how much energy can be used to do somerthing.

How can we use the Hill & Well analogy to understand the behavior of charged objects?

The height of the hill is the electric potential.

The water in the well is the charge.

Voltage = a measure of the different in charge and electric potential between top of the hill and bottom of hill.

The top of the hill has lots of charge and high electric potential

The bottom of ht ehill gas not much charge and has a low electric potential.

What is resistance?

How does it affect current flow?

# data[].attributes.body
How does the behaviour of current and voltage differ between series and parallel circuits?

# data[].attributes.body
What is current?

How does it relate to moving charge?

What does the equation Q = I  t tell you?

# data[].attributes.body
How can we predict the behavior of current and voltage in series circuits using equations and the analogy?

# data[].attributes.body
What is voltage?

How does it relate to the potential difference between two points in a field?

voltage = electric potential per unit charge

# data[].attributes.body
What is an electric field?

How does it relate to charge?

What is the "hill and water reservoir" analogy?

# data[].attributes.body
How does understanding charge help explain static electricity?

Static electricity happens when there’s an imbalance of charges on a surface. When two objects rub together, electrons can move from one to the other, which leaves one with a positive charge and the other with a negative charge.

# data[].attributes.body
A circuit has a battery, wires, and a light bulb or something that uses the electricity that comes fromt he battery and flows through the wires

# data[].attributes.body
there are 2 different types of circuits where electricity flows through

# data[].attributes.body
electrons = negatively charged

protons = positelvy charged

# data[].attributes.body
rubbing the balloon on the jumper causes friction. this allows the electrons to move

# data[].attributes.body
= push awax

the negatively charged electrons repel each other

# data[].attributes.body
means soemthing does not move

# data[].attributes.body
the build up of electric charge (electrons)

# data[].attributes.body
same thing!

electricity= the flow of electrons (a current)

# data[].attributes.body
The voltage decreases when it moves towards the negative and increases when it moves towards the positive. The strength of the field decreases as you go towards the negative. The strength of the field increases as you go towards the positive.
