Energy Basics
This is the ability to do work or cause change.
Energy
These are materials added to homes to reduce heat loss in winter and heat gain in summer.
Insulators
This is the total amount of carbon dioxide and other greenhouse gases that are emitted by human activities.
Carbon footprint
This greenhouse gas is released when we burn fossil fuels like coal, oil, and natural gas.
Carbon Dioxide
What way does heat travel?
Hot to cold
The energy that is stored in an object due to its position is called this.
Potential Energy
Heat transfer through liquid or gasses.
Convection
Driving a car that runs on gasoline contributes to this type of footprint.
Carbon Footprint
This greenhouse gas is released by livestock and other agricultural activities.
When something is hotter it has...
More kinetic energy
This type of energy is stored in food, fuel, and batteries.
Chemical Energy
These are types of insulators used in homes.
Wool, Foam, Fiberglass
You can make your carbon footprint smaller by walking, biking, or taking the bus instead of doing this.
Driving a Car
What layer of the atmosphere traps greenhouse gasses?
Stratosphere (ozone)
The energy of motion is called this.
Kinetic Energy
This is heat transfer through direct contact.
Conduction
A carbon footprint can be reduced by using public transportation or riding a bicycle, which helps reduce these.
Greenhouse gasses
What is the effect that traps gasses in the earth like a greenhouse?
greenhouse effect
If I were to touch an ice cube where would the heat travel?
from your hand to the ice cube
This is the law that says energy cannot be created or destroyed, only converted from one form to another.
The law of conservation of energy
Solar panels and wind turbines are examples of systems that use energy from nature to power homes. These are called these types of energy sources.
Renewable Energy Souces
What are the 4 categories of Carbon Footprint
Home, good, transportation, food,
The accumulation of too many greenhouse gases in the atmosphere leads to this global problem.
Climate Change
If I left the door open and it was 80 degrees inside but 65 degrees outside, would the cold air come in or hot air go out?
hot air go out
