100

What directions do you know in English?

North, South, East, West, forward, backward, left, right, up, down.

100

What is a valve?

A device that controls the flow of a liquid or gas.

100

How are materials classified?

By their properties (e.g., hardness, flexibility, conductivity).

100

Name 3 rigid materials

Steel, concrete, glass

200

What is an air vehicle? What directions can it move in?

plane, helicopter, balloon/aerostat

It can move up, down, forward, backward, left, and right.

200

How can you control the movement of a car?

By using the steering wheel, gas pedal, and brake pedal. 

200

What is an inlet?

An opening or passage for entrance of a liquid or gas

200

What types of materials do you know? Give examples.

Iron - strong, rusts; Copper - conductive, malleable; Aluminum - lightweight, corrosion-resistant

200

What materials are flexible? Hard? Rigid? 

Flexible: Rubber, cloth. Hard: Diamond, steel. Rigid: Concrete, glass.

300

Which directions can helicopters fly? What directions can’t it fly and/or rotate?

Helicopters can fly up, down, forward, backward, sideways. They can rotate in place. They can’t easily fly at high speeds in a straight line like a plane

300

What words are used to describe movement?

Examples: accelerate, decelerate, turn, rotate, ascend, descend, glide, hover.

300

Where and why are heating/cooling systems used?

Heating systems are used in cold climates to maintain comfortable temperatures. Cooling systems are used in hot climates to lower temperatures and maintain comfort. Also used in engines to maintain optimum efficiency.

300

What metals do you know? Name their properties

Iron - strong, rusts; Copper - conductive, malleable; Aluminum - lightweight, corrosion-resistant).

300

What can you do with rubber? (Can you burn, crack, break etc. it?)

You can stretch it, bend it, burn it, and eventually break or crack it.

400

Can a helicopter fly sideways? What directions can it fly in?

Yes, a helicopter can fly sideways. It can also fly forward, backward, up, and down.

400

How to use a remote control transmitter for model plane/model car?

General description should include: Batteries in transmitter and vehicle, turning on both, using joysticks/buttons to control throttle, steering/ailerons

400

How does the car cooling system work? 

coolant circulates through the engine, absorbs heat, flows to the radiator to dissipate heat, and then returns to the engine

400

What is ferrous metal? What is nonferrous metal? 

Ferrous metal contains iron (e.g., steel). Nonferrous metal does not contain iron (e.g., aluminum, copper).

400

What are composite materials and what are their properties?

Made of two or more materials combined, properties are a combination of the individual materials, often strong and lightweight

500

Which directions can/ can’t planes fly?

Planes can fly forward, up, and down. They can turn left and right. They cannot fly sideways or hover.

500

Name parts of the control panel in a car. Explain their functions.

Steering wheel - controls direction, Gas pedal - controls speed, Brake pedal - slows down/stops, Turn signals - indicate direction of turn, etc

500

How does the heating system work? What are the parts of a typical house heating system? How does water move in this system?

Heat source (furnace), distribution system (pipes, ducts), radiators/vents, thermostat. Water is heated and circulated

500

What is an alloy? How can you test alloy? Give some examples of alloys

Alloy is mixture of metals. Testing is done through heating, bend or scratch tests. Some examples of alloys are Steel, Brass, Bronze and Aluminum Alloy

500

How can you test the properties of different materials?

Examples: Hardness - scratch test, Flexibility - bend test, Conductivity - electrical test, Strength - stress test
