Input

Energy that is used by a device (energy that is put into a device)

Output

Energy that is produced by a device

(energy being put out)

Waste

When devices give out less energy than they take in, it is usually because some of the energy escapes into the environment as heat or light energy. (energy lost)

Energy is always changing from one form to another. When energy changes from one form to another, we call it an energy conversion.

The greenhouse effect is a process that occurs when energy from a planet's sun goes through its atmosphere and warms the planet's surface, but the atmosphere prevents the heat from returning directly to space, resulting in a warmer planet

Climate Change

Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, but since the 1800s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels

Current: electrons moving through a circuit (ex. Flowing water)

Voltage: “push” or force used to drive current through the wire (ex. height of the waterfall)

Resistance: things that slow the movement of electrons. (ex. rocks)

The constant flow of electrons through a CIRCUIT. An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space

Examples:

Material “holds on” to electrons more tightly or resists the flow of electrons

Material willing to “let go” of electrons, allows the flow of electric current through

A semiconductor is a material that in some cases will conduct electricity but not in others. This makes it possible to control the electricity and why it is perfect for modern electronics.
