All about StaticElectricity by Shachi Narula

2. What is Static electricity?

We see static electricity every day. It can even build up on us. For example, when we rub our feet on the carpet and then zap something when we touch it. That is static electricity that we have built up on the surface of our skin discharging onto another object. We also see it when our hair gets charged and sticks straight up or when our pant legs keep sticking to our legs no matter what we try and do. This is all static electricity that has built up on the surface of an object.

To understand more about charges , we need to revise about the structure of atom.

1.Induction: Simulation

John Travolta gets a shock but why?

Move john Travoltas leg so that it rubs on the carpet.Now move his hand towards the door knob.What happens?

5.Build an atom Simulation

Try adding electrons to a neutral atom.see what happens!

If the number of protons < the number of electrons =atom becomes electron rich or Negatively charged.

If the number of protons >the number of electrons = Atom is positively charged

Electrons Can Move

The protons and neutrons in the nucleus are held together very tightly. Normally the nucleus does not change. But some of the outer electrons are held very loosely. They can move from one atom to another.

An atom that loses electrons has more positive charges (protons) than negative charges (electrons). It is positively charged. An atom that gains electrons has more negative than positive particles. It has a negative charge. A charged atom is called an "ion."

9. Home Assignment

shachisehgal — 2015-12-12 18:02:59 UTC

Perform a simple static energy experiment at home . Record the video along with your observations.

4. App Download

shachisehgal — 2015-12-14 18:31:10 UTC

Download the App and go through the atomic structure of different elements.

Observe the number of electrons , protons and neutrons in each atom.

3.Go through the flowchart below about the different particles within an atom.

Select Atom in the simulation.

7. Download the Sketchometry App

shachisehgal — 2015-12-14 18:48:58 UTC

Constuct Electronic Configuration models for

Carbon , Oxygen and aluminium ,

Screenshots to be sent on the class group

8.Now you need to download this app(Electric Charge by WIKI Kids , for a recap.

shachisehgal — 2015-12-14 18:57:50 UTC

From this App you can learn:

Explore about the charge that is acquired on the objects due to its interaction with other objects, as observed in daily life.
Discover the properties of electric charge by investigating about various interactions between the objects in real world.
Discuss and differentiate between charged and uncharged bodies of everyday life.
