Use the circuit simulator we've been using in class (
http://phet.colorado.edu/en/simulation/circuit-construction-kit-dc) to make several types of series and parallel circuits. Use the voltmeter and non-contact ammeter tools to find some patters between voltage, current and brightness of bulbs in each type of circuit. Then copy the Venn diagram below into your notebook AND fill it out.
Here's a sample parallel circuit, as well, in case you are confused:
