<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px; margin: 0px; padding: 0px;">Answer the Following Questions After You Complete Your Circuit: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1. Did you like making the circuit? <span style="color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">Yes...  <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. What did you like the least about making the circuit? <span style="color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">When we messed up and had to start over and when our 2nd circuit didn't work. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">3. What did you like the best about making the circuit? <span style="color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">It wasn't very hard. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px; margin: 0px; padding: 0px;">4. Using complete sentences, explain how circuits can be applied in the real world. (List three)
 * <span style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0.5em; padding-bottom: 0px; padding-left: 3em; padding-right: 0px; padding-top: 0px;"><span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px; line-height: 25px;">﻿ Being cautious and careful not to burn your self on the soldering iron can be related to making cautious decisions in your life.
 * <span style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0.5em; padding-bottom: 0px; padding-left: 3em; padding-right: 0px; padding-top: 0px;">You had to follow the instructions so your circuit would work and we have to follow rules to keep us safe and happy:)
 * <span style="margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0.5em; padding-bottom: 0px; padding-left: 3em; padding-right: 0px; padding-top: 0px;">﻿Everything contributes to the functioning of the circuit so you can't leave anything out. In the real world you have to give 100% in everything, not just 95%.

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">5.

We answered them without complaining. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. Did you have a good attitude making the circuits? Explain: <span style="color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">Yes. We had fun and tried our best even when it didn't work. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">3. Were you a whiny baby during the circuit unit? Explain: <span style="color: #000000; font-family: 'Arial Black',Gadget,sans-serif;">No. Lots of things didn't work but we tried to fix them.
