UNIT 10
LESSON 10.1 STATIC ELECTRICITY
Let’s do some magic using the
physics of electricity.
LEARNING LADDER
Starter: Observation, Analysis
and conclusion
Q1 ) Draw the structure of an atom (NOT Hydrogen and Helium)
a) Which part of the atom is moving? Does this particle ever
leave the atom, why?
b) What happens to the over all charge of the atom when the
particle leaves?
KEY
WORDS
Electron,
Proton
Neutron
Charges,
Positive,
Negative,
Neutral,
Attraction,
Repulsion
Q2) Watch the following video on an experiment and answer
the following questions: (use the key words)

a) Why was the balloon rubbed with the
straw?
b) Why was the balloon moving away?
MAIN TASK ( 15 MIN)
Step 1 : Take a plastic ruler, rub against your jacket
– Write down your observation in the shared slides.
Step 2 : Inflate a balloon to an appropriate size.
Rub it against hair of a volunteering partner. Write
down your observation in the shared slides.
Step 3 : Write a concluding statement for your two
observations ( charge goes from where and is
gained where)
HINT :- Use the simulation link in GC to write up the
conclusion for your observation
EXT TASK
Complete the following sentences using words from the list below.
An electric current is a flow of …………….. carried by
…………….. which move round the circuit from the ……………..
terminal of the battery to the …………….. terminal.
A metal contains …………….. that can move about freely inside
the metal. A metal object can only hold …………….. if it is
insulated from the ground.
When two oppositely charged metal objects are brought into
contact, electrons transfer from the …………….. object to the
…………….. object.
An …………….. can become charged with …………….
