What energy transformation do you see in a gas-powered lawnmower?
Chemical energy into mechanical energy
What energy type am I?
Blender, Bicycle, Hand-Drill, Hammering a nail
Mechanical Energy.
An apple hanging in a tree.
Potential Energy.
If the apple were falling, it would have Kinetic Energy.
What resource is found from the ground and can include heat from steam, geysers, which can be turned into electricity or heat? And is it renewable or nonrenewable?
Geothermal, Renewable Resource.
Which of these listed resources are Renewable?
Lumber/Trees
Nuclear
Solar
Petroleum
Wind
Solar and Wind are the only Renewable Resources.
The others take too long to come back, or in other words, are Nonrenewable.
True or False. When energy is transformed, for example
Electrical Energy into Mechanical Energy
New energy is created.
False.
Remember the Law of Conservation of Energy - energy can neither be created nor destroyed.
What energy type am I?
the Sun, Lightbulb, TVs, and a Laptop.
Light/Radiant Energy.
Potential or Kinetic Energy.
When a blender is making a smoothie.
The blender is doing work by crushing/blending the fruit, so that is Kinetic Energy.
What resource is a black or dark-brown rock that can be burned to provide heat or electricity? And is it renewable or nonrenewable?
Coal. Nonrenewable.
(Remember this takes millions of years to form, and it is from plants and animals turned into coal)
What are the two categories of energy that we have talked about, and give an example of each one?
Potential and Kinetic Energy.
What energy transformations would you see in a lamp?
Electrical Energy to Mechanical Energy to Light Radiant Energy.
What is my energy type?
Batteries, Food, and Gasoline.
Chemical Energy.
Potential or Kinetic Energy.
A girl is at her highest point on a trampoline.
Potential Energy.
This is potential energy because she is at her highest point, and will now fall back down, turning the energy into kinetic energy.
Think of this like a roller coaster getting to the top of a hill.
What resource is plants, animal waste, and corn that can be turned into fuel? And is it renewable or nonrenewable?
Biomass. Renewable.
Which is the correct definition for Nonrenewable Resources?
A. resources you have to pay for.
B. resources that come back in a very short period of time.
C. resources that eventually will come back after a long period of time.
This can take millions of years, usually considered nonrenewable if it takes longer than a person's life span.
What energy transformations do you see in a laptop?
Electrical energy to chemical energy to radiant energy.
What type of energy is measured by this device:
Thermal/Heat Energy.
Potential or Kinetic Energy.
A frisbee stuck on top of a wind turbine.
Potential Energy.
The frisbee is stuck, which means it is not moving or doing work, so it has Potential Energy.
What resource is made from pockets of gas in deep in the earth that can be used to provide heat or to power stoves and grills? And is it renewable or nonrenewable?
Natural Gas. Nonrenewable.
(Takes a long time to renew)
Use the information below.
If a small town uses:
50% coal for power
9% solar panels for power
35% petroleum for power
3% natural gas for power
1% biomass for power
2% geothermal plants for power
How much renewable energy does the town use?
The town uses 12% renewable energy.
9% from solar, 2% from geothermal, and 1% from biomass.
What energy transformation would you see in a boulder placed on top of a hill that is about to fall?
Potential Energy to Kinetic Energy.
What energy type am I?
Thunder, Whispering, and Dogs Barking.
Sound Energy.
Potential or Kinetic Energy.
A baseball player is getting ready to hit a home run.
Potential Energy.
The baseball player is about to swing, which means his potential energy is at its highest point, but has not yet become kinetic energy.
What resource is used to spin turbines (mechanical energy) to create electrical energy, which is then stored, but can impact rivers and animals? And is it renewable or nonrenewable?
Hydroelectric. Renewable
(Remember this power is provided by water)
Electricity is the movement of what named particle?
A. Atom
B. Kinetic particle
C. Electron
D. Energy
C. Electron
An electron is the negatively charged particle that moves quickly around to produce electricity.
