In Science we have been learning about electrical circuits. We built series and parallel circuits in a recent lab and explored removing a bulb from each to observe what would happen.
We learned that in a series circuit, if one bulb burns out or is missing, then the circuit will open and none of the lights will remain lit. This is because there is only one path for electric current to flow with this kind of circuit.
We also learned that any bulb in the path of a series circuit receives the same amount of electrical current. With parallel circuits, on the other hand, there is more than one path for electrical current to flow. Therefore, if one bulb burns out, the other bulbs will still remain lit. What fun!! Check out this web site for some fun activities!!

I noticed that there was a paralell
circuit when we put up the Christmas tree, because the first layer of lights were on and the second layer of lights were off.

Trenton you are so smart. Remember to get your five success tickets.
I love the things you put on the Series and Parallel circuit because i already knew all of that information.I got something to relate to on Parallel circuts.When we put up our christmas tree i identified that the lights were a Parallel circuit because one of our lights got switched off and the rest of the lights were remaning on -ferney
I loved the information on the Parallel/Series circut because I knew ALL the information.I had something to relate to the Parallel circuts.When my mom was putting up the christmas tree I identified that the lights because half of the light lit and the other half was off -ferney
We put our Christmas tree up this weekend. Our lights stay lit if one bulb is out. It is a parallel circuit. When we hung the bulbs on the house, if one is out...they all go out. It is a Series circuit. Not fun for dad.

Ferney,
I am so glad you love what we are learning about. You are a wonderful student. Keep up the great work!!

Chris,
Isn't it neat that parallel circuits work if one light goes out. Tell your dad I feel for him. Hope all your decorating went well. Remember to get your five success tickets.

I sure wish that Christmas Lights weren't on a series circuit! I hate when one light goes out and I can't figure out which one it is! :)
I have parallel circuits on my Christmas tree.
Have a Merry Christmas and a Happy New Year!

My dad told me that the Santa out front has a bulb out and no bulbs are working, it has to be a series circuit. I wish they were all parallel.

Carli,
I am so glad you posted a comment. Remember to get your success tickets. I wish you and your family a Merry Christmas!
Love ya,
