Provide an example of CHEMICAL ENERGY -> HEAT ENERGY + LIGHT ENERGY
Burning a candle...
The variable that we purposefully change in an experiment.
What is the independent or manipulated variable?
Using a hot plate to boil water is an example of ______ energy turning to _______ energy.
Electrical energy -> heat energy
This is the variable that is measured in an experiment.
What is the dependent or responding variable?
What is the process of energy in motion?
Kinetic energy.
Draw an energy transformation from mechanical energy to electrical energy.
Windmill is a good example!
Energy transformation of a student riding their bike to school.
Chemical Energy to Mechanical Energy
Heat Energy
These are the variables that we keep the same to make sure that the test is fair.
What is the controlled or constant variables?
A ball is rolled up a hill
Kinetic energy transforming into potential energy
Draw an Energy Transformation with at least 2 steps
Check boards.
Draw a pendulum and label the points where kinetic and potential energies would be maxed
Potential energy at pendulums highest point, Kinetic maxed at central point (assuming pendulum is swinging)
You have decided to test different brands or microwave popcorn to see which brand give you the most popped corn. What is the dependent variable?
What is popped corn.
Identify the independent variable:
A scientist is testing whether the amount of bug spray will affect the number of bug-bites participants receive.
IV: Bug Spray
A solar panel on the roof of a building used to power the lights at home
Radiant energy -> electrical energy -> Radiant energy
Describe the energy conversion when a person has jumped from an airplane.
(Gravitational) potential to kinetic energy.
