The Scientific Method
Jim wants to conduct an experiment to see if light will reflect off different materials. What does Jim have to do before starting his experiment?
What is write a hypothesis?
This is the sum of a system's kinetic and potential energy.
What is mechanical energy?
The sun is an example of this kind of energy.
What is radiant or thermal energy?
A light bulb turns this electrical energy into this kind of energy.
What is radiant?
Energy can be transformed in many different ways. Name the two that use up energy the most.
What is transportation and vehicles
This is the comparison group in an experiment.
What is the control group?
The sun, a light bulb, and an X-ray all use this type of energy.
What is radiant energy?
This is the type of energy found in a compressed spring.
What is potential energy?
This happens to energy when we transfer it from one object to another or transform it from one form to another.
What is conserved.
Energy cannot be ________ nor ________.
What is created nor destroyed
Jasmine is doing an experiment to find out if plants grow better with rock music, country music, or no music. This is the independent variable in the experiment.
What is the type of music?
This type of energy is caused by vibrations, travels in waves, and is sensed by us through our ears.
What is sound?
This is the energy of motion.
What is kinetic/mechanical energy?
A windmill turns wind into this type of energy.
What is electrical?
Energy can take many forms. What are the five types?
What is thermal, radiant mechanical, sound, and electrical
Natalia conducted an experiment to learn more about the kinetic energy of a marble. She rolled a marble down a ramp to see how far it would move a cup at the bottom of the ramp. This might be a reason Natalia got a different result each time.
What is she started the marble at a different place, and/or pushed the marble a different amount, and/or placed the cup in a slightly different place?
A thermometer measures this kind of energy.
What is thermal energy?
Sound and light energy are alike in that they both travel as this.
What are waves?
A toaster turns this kind of energy into this kind of energy.
What is electrical energy into thermal energy?
A clock transforms this energy
What is electrical to sound and light (digital) or electrical to mechanical (analog).
These two words should always be a part of your hypothesis.
What are "if" and "then"?
If you imagine a drop of water about to fall down a waterfall, at the top of the waterfall the drop of water has this kind of energy.
What is potential energy?
This is energy that travels in the form of light.
What is radiant energy?
This kind of energy is observed in lighting, circuits, and in living things.
What is electrical energy?
Coal and natural gas are fossil fuels that are transformed from this type of energy.
What is chemical and thermal.
