1. Use the table below to record your measurements and patterns you notice. You decide where will be the most useful places to take measurements, and how many to take.

Circuit Label the places where you decide to measure current and voltage. Try several places.	Current Measurements (Amps)	Voltage Measurements (Volts) .	What patterns do you notice? Where is the current the same? Where is it different? Where does the voltage change? Where doesn't it change? How do the different circuits compare?

1. Compare the patterns you see in a series circuit to the ones you see in parallel and complex circuits. Write rules about voltage and current for each type of circuit. For example, "In a series circuit, I see that the current..., whereas in a parallel circuit I see...".

1. Predict from your rules above, the order of the light bulbs in these circuits from brightest to dimmest. Some bulbs might be the same brightness.

1. Order the bulbs by brightness.

1. After you make your rankings, build circuits to check your answers and list the correct ranking below. Insert images from the simulation to support your sequence.

1. Did your rules allow you to correctly rank the bulb brightness? If not, correct your rules in #6.

1. Did you use any meters to help you make your list? If so, explain why.

10. If you want to make a flashlight and have two batteries and a lightbulb.

1. Predict how you would hook them up to make the brightest flashlight, and explain why.
2. Build circuits to check your answer and insert images from the simulation for evidence.
