balances the negative charge

of the electrons the atom is balanced.

Statement of Inquiry:

Scientists study systems, their interactions with other systems, and their transformations to create scientific innovation which reduce risk.

Factual Inquiry Question:

What is an electron?

Conceptual Inquiry Question:

How are charges created?

Debatable Inquiry Question: Can electrostatics

have enough charge to harm someone?

If an atom is not balanced it can be persuaded to give up an electron from its outer shell.

Electrons migrate to other objects all the time

Charge just transfers to the other object

An atom that gets its electrons taken away is called an ion.

PITH BALL ACTIVITYESSENTIAL QUESTION: How can I show the force between two objects by creating a charge between them?

BACKGROUND: A pith ball is a very small, lightweight object that picks up electric charge quite well. A charged pith ball works well to show the force between two charged objects.

Hypothesis: If ____________________________________________,

_______________________________________________________

then ____________________________________________________.

there is a charge be-tween

two objectsthere is a force (push or

pull)

PITH BALL ACTIVITYDIRECTIONS:Step 1: Rub the glass rod is with the fur or silk. the silk rubs some electrons off the rod. The rod thus becomes positively charged.

Step 2: Place the glass rod near the two pith balls. What happens? (Explain in your own words below and draw a picture to represent the reaction)

Step 3: Now take the rubber rod and rub it with fur or silk. the rod rubs some electrons off the fur. The rod thus becomes negatively charged and attracts the positively-charged pith balls.

Step 4: Place the rubber rod near the two pith balls. What happens? (Explain in your own words below and draw a picture to represent the reaction)

FOLDABLE-THE ATOM AND THE PITHBALLComplete the following foldable by cutting out the boxes and cutting

the dark solid lines. The foldable are in the back of your class workbook. Glue the gray part in your book and place the answers

underneath the tabs.
