Types of Energy
What are the two main types of energy that all other forms of energy can be categorized under.
Kinetic and potential
What do we call energy that comes from moving water?
Hydropower/hydroelectricity
The law of conservation of energy states that energy cannot be _________ or _________.
Created or destroyed
The average global temperature usually changes by a few degrees every hundred years, so climate change is natural.
True or false.
False.
What is energy?
The ability to do work or make something happen.
An example of this type of energy is the energy stored in the bonds of the atoms and molecules in our food.
Chemical
Name three fossil fuels.
Oil, natural gas, and coal
Energy can transform from one type into another. True or False.
True. The law of conservation of energy tells us that it can.
Greenhouse gases are found in this layer surrounding the Earth.
Atmosphere
What does it mean when we say that Indigenous people see themselves as "stewards" of the Earth?
Indigenous people believe they have a responsibility to protect and take care of the Earth.
You are holding a ball at the top of the hill. What type of energy does it have?
Gravitational potential energy
Geothermal
There is 1000 times more energy on Earth now compared to when the dinosaurs lived. True or false?
False. There is the same amount of energy because energy cannot be created or destroyed.
Name two types of greenhouse gases.
Methane, carbon dioxide, nitrous oxide
Oil is a natural resource.
True or false.
True. A natural resource is something that comes from nature that humans use. Examples include water, sunlight, wind, minerals, oil, wood, etc.
Name the types of energy that travel in waves.
Sound and light energy.
What does it mean if an energy source is non-renewable?
A non-renewable energy source is one that cannot be used over and over again. There is only so much on Earth, and because it takes so long to form, when we run out of it, we will not be able to get more.
What types of energy often get "lost" to the environment during energy transformations.
Heat, light, and sound energy
Why are greenhouse gases a good thing?
They keep the planet warm enough to support life.
What is an example of a human activity that contributes to climate change?
Driving a car, using electricity, manufacturing and processing new items, burning fossil fuels, cutting down trees, etc.
This type of energy is the total energy of an object due to its movement and position, and includes both the object's kinetic and potential energy.
Mechanical
Name a benefit and drawback of renewable energy sources.
Benefits: They can be reused over and over again since they are formed so quickly, and they don't pollute the Earth as much as non-renewable energy sources.
Drawbacks: You cannot get as much energy from them as fossil fuels, and the amount of energy you can get from them depends on the weather.
Describe the energy transformation that happens when you eat a sandwich.
You are using mechanical or kinetic energy to move your teeth while chewing, and some of that is transformed into sound energy. When you digest the sandwich, your body transforms the chemical energy from the food into kinetic energy to power your movements.
Explain what the greenhouse effect is.
Gases in the atmosphere trap heat from leaving Earth, which warms the planet.
Why is water so important to the Anishinaabe people?
Water is sacred to the Anishinaabe. Water is seen as a medicine that nourishes us. Water has memory and spiritual significance.
