Energy resources & conservation
This type of energy comes from natural sources that can be replaced, like the sun or wind.
What is renewable energy?
This natural force makes wind turbine blades spin.
What is wind
These are the physical parts of a computer or system that you can touch.
What is hardware?
These are instructions that tell a computer what to do.
What is software?
or
What is code?
This term describes a group of parts working together.
What is a system?
Solar, wind, hydro, and geothermal are all examples of this kind of energy resource.
What are renewable energy sources?
These long parts of a wind turbine catch the wind.
What are wind turbine blades?
A keyboard, motor, and sensor are examples of this.
What is hardware?
Programs written in code are examples of this.
What is software?
or
What is code?
These three parts describe how a system works from start to finish.
What are inputs, processes, and outputs?
This renewable energy source uses sunlight to produce electricity.
What is solar energy?
This tall structure holds the turbine blades high above the ground.
What is the tower?
This device collects information from the environment, like light or temperature.
What is a sensor?
This software allows users to interact with a device, like apps or games.
What is application software?
This happens when a system uses its output to improve what it does next.
What is feedback?
This renewable energy source uses flowing water to spin turbines.
What is hydropower (or hydroelectric energy)?
This part of the turbine changes motion into electrical energy.
What is a generator?
This part of a system moves or controls something, such as a motor or a servo.
What is software?
This type of software uses sensor data to make decisions automatically.
What is control software?
or
What is the operating system?
This happens when a system uses its output to improve what it does next.
What is feedback?
This term describes how using renewable energy helps reduce environmental pollution.
What is reducing greenhouse gas emissions?
This science concept explains why turbine blades are shaped like airplane wings.
What is lift?
This small computer controls hardware using inputs and outputs.
What is a Micro:bit?
or
What is a Microcontroller?
This step-by-step set of instructions is used to solve a problem.
What is an algorithm?
This type of thinking examines how all parts of a system affect one another.
What is systems thinking?
