Scientific Models
If a scientist uses a model and it is confirmed, that means..
They keep the model they initially used
Are protons negatively charged, positively charged, or nuteral?
Positively charged
Where does excess charge build up on an insulator?
The surface
When two different insulators are rubbed together, electrons can transfer from one ____ of an insulator to another.
Surface
Conductors are materials in which ___ flow easily.
If a scientist uses a model and it is refuted, that means...
They use new evidence to modify their model.
Are neutrons negatively charged, positively charged, or nutural?
Trick question, they are uncharged.
A temporary ___ of + and - charges within a neutral object
Seperation
In an Insulator, what charges are tightly bound within the atoms?
Electrons
Yes
Scientists use ___ from past experiments to revise models.
Observations
Are electrons negatively charged, positively charged, or nutural?
Negatively charged
A charged object forces ___ charges in the neutral object to shift away or toward the surface.
After the two insulators are rubbed, are the electrons trapped until runned onto another insulator?
Yes
Do charges stay on the surface of a metal conductor?
No, they move freely throughout the metal
Scientists guide the making of ___ that haven't been done yet.
Predictions
Do "like charges" repel from each other, or attract each other?
They repel
Charges do not move within the ___. They stay on the surface where electrons were gained.
Insulator
Insulators are ____ that may build up charges on their surface.
Materials
Are conductors like this;
---> - ---> - ---> -
or like this?;
+ - + - + - +
---> - ---> - ---> -
What is the purpose of scientific Models?
Tools that scientists use to explain how things work
Negative
1. Materials like rubber and plastic tend to GAIN_____ charges
2.Materials like rabbit fur and glass tend to LOOSE____ charges
1. Negatives
2. Also negatives
Tightly bound atoms surround the...
Nucleus
Because they are highly mobile, ___ can move freely in conductors
Electrons
