Exploring Tech Concepts

What is a magnet and how does it work?

• A magnet is an object that can only attract gold and silver.

• A magnet is a type of battery that stores energy.

• A magnet is an object that produces a magnetic field and can attract or repel certain materials.

• A magnet is a device that generates electricity through heat.

Name two types of magnets and their uses.

• Permanent magnets and electromagnets.

• Wires and resistors

• Solar panels and batteries

• Refrigerators and toasters

What is an electric circuit?

• A device that stores electrical energy.

• An electric circuit is a closed path through which electric current flows.

• A type of electrical appliance that uses batteries.

• A series of batteries connected in parallel.

What are the main components of a simple electric circuit?

• Power source, conductive path, load

• Battery, insulator, fuse

• Power generator, resistor, switch

• Voltage source, circuit breaker, capacitor

How does electricity flow in a circuit?

• Electricity moves in a straight line without any resistance.

• Voltage is not necessary for electricity to flow in a circuit.

• Electricity flows in a circuit through a closed loop driven by voltage, allowing electrons to move from the power source through conductors.

• Electricity flows in a circuit only when the circuit is open.

What is the difference between a series and a parallel circuit?

• A series circuit has multiple paths for current, while a parallel circuit has a single path.

• In a series circuit, components are connected in a grid, while in a parallel circuit, they are in a line.

• A series circuit has a single path for current, while a parallel circuit has multiple paths.

• A series circuit allows for independent operation of components, while a parallel circuit requires all components to function together.

What are the different types of refugees?

• Historical refugees

• Cultural refugees

• Political refugees, Economic refugees, Environmental refugees, Religious refugees, Asylum seekers

• Social refugees

What challenges do refugees face when relocating?

• Refugees have no issues finding housing and healthcare.

• Refugees easily adapt to new cultures and languages.

• Refugees receive unlimited financial support from governments.

• Refugees face challenges such as language barriers, cultural differences, legal hurdles, limited access to jobs and education, and psychological trauma.

What types of food are commonly provided to refugees?

• Staple foods like rice, beans, lentils, canned vegetables, and pasta.

• Luxury items like caviar and truffles

• Exotic fruits like mangoes and pineapples

• Fast food items like burgers and fries

What is scrap metal and how is it recycled?

• Scrap metal is discarded metal that can be recycled by melting it down to create new products.

• Scrap metal is discarded metal that is thrown away without any processing.

• Scrap metal is only valuable if it is painted or coated.

• Scrap metal is a type of plastic that cannot be recycled.
