Electrostatic Lab

Electrostatic Lab

What materials will you use?
I will use the virtual lab and elements provided by the class

What would you measure?
I will measure the static electricity with a neutrally charged balloon

What results do you expect?
I expect that the balloons charges and sticks to the wall.

What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair.

EXPERIMENT

Bring together the balloons but not touching each other.

Rub a balloon in sweater.

Rub several times the balloon and the sweater so there is more attraction

Bring the balloon as close to the wall as possible but without touching.

OBSERVATION

They kept the same, so they couldn’t be charged.

The balloons sticks to the sweater because it was attracted to the sweater and charged.

There is a greater exchange of electrons so the balloon get more charge and sticks more to the sweater.

Nothing happened, objects kept the same

Experiment

Rub the uncharged balloon with the wall

The balloon is more attracted to the sweater that to the wall

Rub both balloons together

Observation

The balloon kept the same, it wasn’t charged.

The sweater became proton charged, this means that the balloon will be more attracted to the sweater than to the wall.

Objects kept the same because non of them was charged.

After touching the blue balloon with the sweater, what kind of charge is on the balloon? Explain how observations support this conclusion.

When I rubbed the balloon with the sweater, the balloon was charged negatively and this two exchanged electrons. The blue balloon was attracted to the opposite, which was the sweater.

After touching the yellow balloon with the wall, what kind of charge is on the balloon? Explain how observations support this conclusion The wall and the balloon didn’t attract because the wall has a more rough and difficult surface. And the balloon wasn’t
