Scientific Method
What is the first step of the scientific method?
What is a question or observation?
What energy is defined by measuring the motion of molecules of an object?
What is thermal energy?
This energy is effected by the height of an object.
What is gravitational potential energy?
Heat transfer is really neat. It always goes....
What is from hot to cold?
What energy transformation is happening here:
A rock falls from a cliff.
G Potential --> Kinetic
What type of question implies a change and has a cause and effect relationship?
What is a testable question?
A material that allows heat to easily pass through it is called what?
What is a conductor?
This energy is about the movement of objects.
What is Kinetic Energy?
Heat can be transferred. What does transfer mean?
What is moved from one location to another?
A drummer playing the drums
Kinetic --> Sound
What is the dependent variable in the follow hypothesis:
When there is less oxygen in a body of water, rainbow trout suffer from more lice.
What is the amount of lice?
What are the three ways heat is transferred that we learned about?
This energy is what is stored in our food.
What is chemical energy?
When heat is transferred through direct touch, what is that called?
What is conduction?
What energy transformation is happening here:
A lamp is on
Electrical --> Light
The dependent variable is on what axis of a graph?
What causes a swing to stop moving when there is nobody pushing it?
What is friction?
What is chemical energy?
What is from the warm lake to the cool breeze? Extra: The rising and cooling of air causes a convection current.
What energy transformation is happening here:
Ms. Farmer goes to the gym after eating a rice krispie treat
Chemical --> Thermal (digestion) --> Kinetic
chem --> kinetic okay
Why can you only have one independent variable in an experiment?
-Answers Vary-
(You have to know if the one thing you are changing is effecting the results.)
Where does the kinetic energy of a book that was sliding across a table, but came to a stop go?
What is friction transfers the energy to thermal energy in the table and book?
This energy travels in waves and is caused by vibrations.
What is sound energy?
What is electromagnetic waves?
What energy transformation is happening here:
Turning the brightness up on your phone
Chemical --> Light
