PPT-Electric Charge Remember the tipsy tape pieces?

What happened when both pieces of tape were stuck to the same surface then brought close to each other the tape pieces moved away from each other What is the scientific word for this action. Balloon and Scotch Tape Electroscope Lab. Balloon Lab. Big Idea. : There exist electrical charges which can repel/attract one another.. Up and atom!. An atom is the smallest unit of a particular element.. . HW2:Chapter 21, Pb.1, Pb.12, Pb.13, Pb.25, . Pb.31, . Pb.36,Due Wednesday, Jan.25. 21.1 Electric Charge, q or Q. Charge comes in two types. 1e = 1.6x10. -19. Coulombs (unit of charge) fundamental unit of charge. Students observe phenomena in which:. A balloon sticks to the wall after being rubbed on hair;. (A plastic bottle picks up small pieces of paper after being rubbed on cloths;. Etc. …). 1. The formatting and presentation for this sticky tape experiment is from the NGSS Rollout 3.

Everything is electric!. Charges can be separated between two objects. Charge is always conserved. From the sticky tape investigation, we can conclude that there are two different . Electrons on an insulator (zoomed in).. Zoomed out – difficult to “see” individual electrons . smooth distribution of charge..  Like charge is “smeared” on the insulator.  . - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -.

Looking forward at …. how objects become electrically charged, and how we know that electric charge is conserved.. how to use Coulomb’s law to calculate the electric force between charges.. Charge. Which items in the Sticky Tape Lab exhibited a charge?. What behavior was displayed that makes you believe those objects were charged?. No Charge?. Were there items that were not charged (neutral)?. Tape lab (pt. 1). Make a tape “Flag”. Make a top (T1) and bottom (B1) tape sandwich. Make another pair of top and bottom tapes (T2 & B2). Directions. Hang T1 and B1 off the end of the table.
