Circuits!!!


Circuits are everywhere!

Tell about an electric circuit that is important to you or that you use every day. How does it work?





For example, I need an electric circuit for my computer everyday to update the 4th grade science blog. If I unplug my computer, I open the circuit, and electricity doesn't flow.



Bonus: What investigations did you do with circuits this year?
