Do you know some thing about a Robo-car?
Did you hear about car which drives itself?
Modern inventions
This Robo-car is a very interesting thing. It’s a vehicle which can drive itself , without a driver .It uses a computer sensor .
A sensor is a device that senses or measures something in the environment , and changes it into a digital signal.
A computer sensor control the speed and direction of the car
This sensor is connected to a computer .The sensor measures the space which surrounds the car.
It then sends this information to the computer , which controls the car.
A sensor is a device that senses or measures something in the environment , and changes it into a digital signal.
Study these definitions
is a device which senses and
measures something.
A sensor
is a device for measuring very
small dimensions.
A micrometer
A handle drill is tool that makesholes in materials
A robo-car is a vehicle which is driven by a computer.
is the ability of a material to break easily when struck
with a hard blow .
For example:- cast iron is very brittle هش
Brittleness
is the capacity of a material to become liquid when heated
For example:- ,iron is very fusible
Fusibility
is the ability of a material to be hammered into thin sheets without breaking
For example , lead is very malleable
Malleability
Tenacity is the capacity of material to have resistance
against a pulling force.
For example , steel is very tenacious.
Have you ever walked towards an automatic door in a shopping mall where the doors open as you approach?
In your opinion How this work ?
They works with a sensor. But now we must know what is a sensor?
A laser beam shines at a light sensor in front
of the door.
When somebody walks between the light source , and the sensor , the path of the beam is blocked .
The sensor detects a reduction in the level of light and sends a signal to the control box .
The control box makes the door open . This is briefly how can you walked through the blocked doors .
There are many examples where sensors are used , such as altitude sensors which detect the height of the aero plane .
Also , heat sensors such as thermostats which detects temperature ,and which circuits on and off , We can see also voice sensors in computers which can recognizes someone’s voice and responds to it .
Let’s arrive to the intelligent house of the future. Can you enter your house without opening it with a key? . .
Come in ! Don’t worry . To Unlock the door , just press a button on this small pad. If you are away from home when your relatives visit ,you can open the door for them.
Can you imagine this house in which every appliance is controlled by computers and sensors? What kind of sensors do you think would be needed?
How does the door open? There are no wires . There is only a sensor and a tiny chip .The sensor is a device which “reads “ your fingerprints, and changes it into a digital signals
This is a new technology which allows machines to recognize a person , perhaps in the future , the doors of houses will open automatically when their sensors recognize the eyes of their owners .
Learn some vocabulary
Fingerprint – sensor – antenna – screen – refrigerator – pad signal –chip – security – digital – domestic appliances- VCR -
Come on ! There are some appliances we all know very well
Firstly This is a very common appliance which is found in many homes : Its purpose is to allow you to watch films and other programmes on the screen .It receives signals from transmitter through an antenna , and it changes these signals to moving
colour pictures and sounds.
This appliance has a large container with a door . On top of the container there are four gas burners .Food can be placed inside the container and the container can be heated until the food is cooked
This is a very useful appliance in hot weather .Its function is to control the temperature inside a room . When the room is becomes too warm ,a compressor switches on and a fan blows cold air into the room.
The purpose of this appliance is to play music and radio programmes .It consists of a CD player, a radio tuner , and an amplifier and two large speakers.
The function of this appliance is to record and play back television programmes .
It receives signals via an antenna , and converts these signals to moving pictures and sounds . It then records the moving pictures and sounds onto a tap cassette.
I can use this appliance also in hot weather , but here in order to keep food and drinks .If we put food in very hot weather it will damage immediately ,so we all need this appliance in our houses.
It’s a vehicle , supported and propelled by a cushion of air , which is used for carrying people and goods quickly across both land and sea .
It’s a vehicle , supported and propelled by a cushion of air , which is used for carrying a single rider quickly over land
It’s a very large satellite powered by solar energy and located at an altitude of 400 km above the Earth , in which scientists carry out experiments at zero gravity .
Let’s know what metal nouns which are useful in metal work , there are some nouns such as conductivity ,elasticity ,hardness, toughness, and tenacity .Also there are many processes such as bluing , annealing ,casting ,and forging.
Conductivity is the capacity of transmitting heat and electricity
Ductility is the ability to be stretched into fine wire without breaking
is the ability of a material to return to its original shape after it has been deformed
Elasticity
is the resistance to deformation ,bending , and cutting
Hardness
is a process in which is made corrosion-resistant by heating and then quenching it in oil
Bluing
is a process in which metal is made softer by heating it gently
Annealing
is a process by which metal is made into metal shape by melting it and then pouring it into moulds
Casting
is a process in which ductile metal is made longer and thinner by pulling it through a hole
Drawing
is a process by which metal is shaped by heating it and
then hammering it .
Forging
is a process in which metal is hardened by heating it and then quenched it in water
Hardening
is a process by which hard steel is made less brittle by heating it and then cooling it
Tempering
Study these sentences
To deform something means to change its shape
To quench a hot metal means to cool it by placing it in a cold liquid
Imagine ,that you have been given a job as a tourist guide to show a foreign tourists around
the main touristy sites of Egypt , Which sites would you
take them to?
You must take them to visit the citadel of Salah El Deen , The new library in Alexandria .Also the Red sea coast and Khan El Khalily.
Some sentences about people ,
places, and events
Sham El Nessim is a day on which Egyptians walk in parks and enjoy the beginning of spring .
The Citadel in Cairo is a place in which
Salah El Deen built his fortress.
The new library in Alexandria is a place Where

Describing Egypt to a tourist
What is the Aswan High Dam ?
It is a hydroelectric dam which controls the flow of the Nile
They are places where the River Nile flows steeply downhill.
What are the Nile Cataracts ?
Let’s study some grammar
Relative pronouns
Relative pronouns are used instead of the object or subject
A computer sensor is a sensor whichis connected to a computer
Signals are sent to the computer. The computer then controls the car .
Signals are sent to the computer , which then controls the car.
Some relative pronouns
Where = in which this is for place
