GCSE Design and Technology, Systems and mechanisms. Usually met in years 9 to 11.
Learn how energy is generated and stored, and how electronic systems use inputs, processes and outputs.
What you practise
Renewable and non-renewable energy
Batteries and storing energy
Sensors, microcontrollers and outputs
Starts with energy sources and builds to sensors in electronic systems. Practice moves up a level when a round goes well and down when it does not.
Sample questions
Each sample comes with the method and the reason every wrong option is wrong. Real practice rounds are ten questions at your level.
Sample question, level 2 of 5
Which term means: plant or animal material burned or broken down to release energy?
Rechargeable battery
Renewable energy
Kinetic pumped storage
Solar panel
Biomass
Show the answer and method
Answer: E, Biomass
The method: Biomass means plant or animal material burned or broken down to release energy.
Why the other options are wrong:
A, Rechargeable battery: Rechargeable battery means a battery that can be charged and used again many times.
B, Renewable energy: Renewable energy means energy from sources that will not run out, such as the sun and wind.
C, Kinetic pumped storage: Kinetic pumped storage means storing energy by pumping water uphill, then letting it flow down through turbines when needed.
D, Solar panel: Solar panel means a panel that turns sunlight into electricity.
Sample question, level 4 of 5
Which term means: the part of an electronic system, such as a microcontroller, that decides what happens?
Kinetic pumped storage
Microcontroller
Thermistor
Rechargeable battery
Process device
Show the answer and method
Answer: E, Process device
The method: Process device means the part of an electronic system, such as a microcontroller, that decides what happens.
Why the other options are wrong:
A, Kinetic pumped storage: Kinetic pumped storage means storing energy by pumping water uphill, then letting it flow down through turbines when needed.
B, Microcontroller: Microcontroller means a small programmable chip that can control an electronic system.
C, Thermistor: Thermistor means a sensor whose resistance changes with temperature.
D, Rechargeable battery: Rechargeable battery means a battery that can be charged and used again many times.
