100 Days of Science-- #7 Making Static Music

Now that our field trip season is starting to die down I am purposely making more time for science and when we saw this in one of our books we knew we just had to try it!



I love quick and easy demonstrations for science that don't require a lot of obscure supplies.  For this lesson you will need:

A large bowl
Tin foil
Elastic band
Balloon

Step 1:  Stretch the foil over the bowl and use an elastic to hold the foil tightly in place.  You want to make the foil as wrinkle free and drum tight as possible.



Next blow up a balloon.


Break some tiny pieces of foil off and roll them into tight little pieces (or keep small, flat flakes) and put them on your foil drum.


Rub the balloon against your hair and get it nice and static filled. 


Then hold the balloon over the foil drum and watch/ listen as the static attracts the tiny pieces of foil.  you can see some of them getting sucked up to the balloon and they fall back to the bowl with a plink sound.  Making noise like a drum.

our pieces were too big the first time so we tried again. 


This one stuck to the balloon for a second 

Then plunk right back down on the drum.

See the one strand of foil in the far right corner?  It's vertical between the balloon and the drum.

      They thought it was lots of fun! I love science and I'm so glad I've been able to pass that love on.

Favorite TV Shows Growing Up in the 80's and early 90's

Do you remember the TGIF lineups on Friday nights? I can remember planning sleepovers and time with friends around TV Show lineups of our favorite shows... or else trying to set the VCR to record our favorite shows if we weren't going to be home. And through the years I had SO MANY favorites! Growing pains aired in 1985 which put me around age 8 and it stayed on the air until I was 15 or so; I'm pretty sure most people in my age group watched mostly for Kirk Cameron and all his antics.  I still have a soft spot for family sit-coms!  The Facts of Life aired when I was just 2  and stayed on the air until I was 11 so I'm sure the episodes I remember so fondly were either some of the later ones and then reruns shown later on when I was old enough to watch from the beginning. I think everyone would have loved an Edna Garret in their lives.   Benson another sitcom that began airing when I was just 2 and was done by the time I was 9 (another one I must have watched mainly through

Dollar Store Candy Cane Wreath

Today I am linking up with some fellow bloggers for a Dollar Store craft challenge.  I don't often participate in these challenges since I try to stay away from our local Dollar Stores; I find they can be quite dangerous for me!  I knew this was the perfect time to find some inexpensive holiday decorations though and I just LOVE how my wreath turned out!  I hope you stop by and see what the other hosts are sharing. Meet this month's co-hosts! Across the Blvd | Purple Hues & Me This Autoimmune Life | Our Unschooling Journey Domestic Deadline | Sew Crafty Crochet Stone Cottage Adventures | Sum of Their Stories | Two Chicks & a Mom I bought the candy cane wreath base and a few rolls of mesh (not knowing how many I'd need I bought waaay to many; I only ended up using one white roll and one red roll. Using some chenille stems I already had on hand I attached the mesh to the wreath base trying to alternate the white

Things That Make Me Laugh

Image
I loved the challenge of this week's list for our 26 lists link up.  I don't know about you but I really need to laugh more lately.  It's such a great stress reliever. 1.  Books-- I love a good funny book that makes me laugh out loud.  I haven't read one in a while but if you have any recommendations I'm all ears.  The last book I can remember making me laugh was the Un-Honeymooners. 2  The boys being silly. 3.  Watching shows like America's Funniest Videos or Family Feud. 4. My husband.  Most people don't realize it but he's actually pretty funny and often makes me laugh. 5.  Whenever my sisters/ family get together and we get to reminiscing (particularly if my Aunt Elaine is around) we end up laughing so hard at all the old family stories that we are all in tears by the end of the night.  It's fabulous. 6. Movies like Mom's Night Out, Christmas Vacation, and Grown Ups make me laugh out loud. 7.  When my boys were youn
