Emma is heating three pots of water on the stove. Each pot is the same size, made of the same materials, and is set to the same heating level. Each pot has a different amount of water.
Which pot of water will take the least amount of energy to bring to a boil?
The pot with the least amount of water
This type of energy is found in moving objects.
Kinetic Energy
*DAILY DOUBLE*

Roller Coaster
An advantage of this nonrenewable energy source is that it is cleaner than fossil fuels.
Nuclear Energy
Olivia is designing a soccer ball that conserves all of its kinetic and potential energy. She drops the ball to the ground from a height of 2 meters.
(Assume NO friction or resistance)
If it really works, how high should the ball bounce?
Exactly 2 meters
An incandescent light bulb gives off both _____ and _____ energy when it is on.
Heat and Light (electromagnetic)
Only about 12% - 30% of the chemical energy from gasoline is used to move a car down the road.
Most of the remaining energy (58%-62%) is lost as _____ energy.
Thermal (heat) Energy
*DAILY DOUBLE*
When traveling down a hill on a roller coaster, is gravity pushing you down, kinetic energy pulling you down, both, or neither?
Neither
(gravity pulls down the hill, kinetic energy pushes down the hill)
This renewable resource is often used by companies to make electricity, especially here in Arizona.
Solar Rays
(sunlight is also acceptable)
What does the term “conservation” mean in regards to energy?
Energy is not created or destroyed, the same amount is always present in some form
Whales use this type of energy to communicate with each other.
Sound Energy
Friction between two surfaces causes _____ energy to transform into _____ energy.
Kinetic and Thermal
According to the Newton's _____ Law, an object in motion will stay in motion. This means that the kinetic energy built up from the fall down the first hill could keep it going forever.
First
(Law of Inertia is also acceptable)
This renewable resource is colorless, odorless, tasteless, and kills thousands of people every year.
Water
(H2O and Dihydrogen Monoxide are also accepted)
