ATOMIC STRUCTURE AND CHARGED PARTICLES

POSITIVE AND NEGATIVE CHARGES

CHARGED OBJECTS AND STATIC CHARGE

ELECTRIC FORCES - INTERACTIONS BETWEEN CHARGED PARTICLES

THE EFFECT OF DISTANCE AND CHARGE ON ELECTRIC FORCES.

WATCH THE BRAINPOP ON STATIC ELECTRICITY LOCATED HERE.

THEN READ THE SHORT ARTICLE ON STATIC ELECTRICITY LOCATED HERE.

IN YOUR SCIENCE NOTEBOOK, COPY AND ANSWER THE FOLLOWING QUESTIONS. USE A BLANK PAGE WITH A PROPER HEADING THAT YOU CAN PASS IN.

1) MOST CARPETS ARE MADE OUT OF POLYESTER AND SOCKS ARE MADE OF WOOL. WHY CAN SHUFFLING ACROSS A CARPET IN YOUR SOCKS BE SUCH A “SHOCKING” EXPERIENCE?

2) WHY ARE RUBBER BALLOONS SO EASILY CHARGED BY RUBBING THEM ON A WOOL SWEATER?

NOW PLAY WITH THE PHET SIMULATION TITLED BALLOONS AND STATIC ELECTRICITY.

IN YOUR SCIENCE NOTEBOOK, COPY AND ANSWER THE FOLLOWING QUESTIONS:

3) WHY DOES THE BALLOON STICK TO THE SWEATER AFTER IT IS CHARGED?

4) WHY DO THE NEGATIVE CHARGES ON THE WALL MOVE AWAY FROM THE CHARGED BALLOON AS IT IS BROUGHT CLOSE TO THEM?

Did you already do this work?

Challenge Activity: How can you use two balloons to show that similar charges repel each other?

Brainstorm, build and demonstrate.

OPEN UP YOUR NOTES TO SHOW YOUR HOMEWORK.
