We continued our discussion about electricity today with an example of static electricity. Mrs. Forst joined morning meeting with a balloon stuck to her scarf. We asked her if she used tape or glue to make the balloon stick, but when she moved the balloon away it was clear that she had not used any sticking agents. This was the conversation that followed:
H.P. – It’s static!Mrs. Pless – What is static?A.H. – It’s something that’s sticky.Mrs. Pless – Is tape static?Class – No.Mrs. Pless – Tape is sticky.J.J. – Not every sticky thing is static.S.C. – Static sticks to some balloons but not all of them because some of them are balloons I’ve never heard of before.T.O. – Not everything is static because somethings stick but some do not. I have a rubber spider and it sticks to you.J.W. – Static is like glue that sticks to the table.Mrs. Forst – I’m going to bring around the balloon and I want you to tell me if you think its sticky. What do you think?Class – Not sticky.
A.R. – It’s like a magnet!Mrs. Forst – (wipes the balloon of the static charge) Now, watch the paper when I put the balloon over the paper, it isn’t moving. What do I need to do?H.P. – Rub your scarf on it again.J.W. – When you were rubbing the balloon with the scarf you tried to squeeze it and the paper was getting up to the balloonA.J. – It sticks because you rubbed the scarf on the balloon and the paper was dancing.S.B. – You know that balloons that are purple they always stick because the string is so deep that they make it like that.S.C. – Balloons can stick a little bit. Green ones can and purple ones can stick because you can wipe them with red scarves and make them stick.A.H. – If you get one hundred balloons it wont stick.
