The atomic mass of a C-14 isotope of carbon. Remember the number of protons in carbon is 12.
What is 26?
(14 means there are 14 neutrons in this isotope of carbon, and still remains stable. Carbon 14 is used to figure out how old objects are)

2. Colour change
3. Precipitate formed
4. Gas produced
5. Can’t reverse the change?

The formula to find voltage.
Think of what each symbol means, and what unit is used for that symbol.
What is V = I × R?
(V = volts V)
(I = Amps A)
(R = Resistance Ohms)

The cost for power is 8 cents per kW×h.
One month a house uses 2000 kW of power.
The amount they pay is...
What is $160.00?
Convert 8 cents into dollars, move the decimal place to the left two places so it is $0.08.
Then multiply $0.08 × 2000 = $160.00.

5. Record Data / Observations
6. Analyze Data
7. Form a Hypothesis

(Four types and their location).
What is:
Metals - left of stair case
Metalloid - stair case
Non-metals - right of stair case
Nobel Gas - far right column.

The eight steps of how an electric circuit works.
What is:
1.Batteries have a positive and negative end.
2.Electrons are moving in a circuit.
3.The hot wire goes from the negative end to the load.
4.Electrons are repelled from the negative end of the battery with a lot of force to the load.
5.The load changes to a different from of energy.
6.The neutral wire goes from the load to the source.
7.The electrons are attracted to the positive end of the source.
8.Electrons get recharged and send back out, keeps going in a loop.
