Scientific Method & Variables
The variable that changes on purpose or intentionally
What is INDEPENDENT VARIABLE?
This is considered your prediction for the outcome of an experiment, also known as an educated guess.
What is a HYPOTHESIS?
This transfer of energy is through direct contact.
What is CONDUCTION?
What is CHEMICAL ENERGY?
A solar panel is an example of what energy transformation? (It's original from is converted into which form)?
What is RADIANT > ELECTRICAL?
The variable that is measured depending upon the variable that changes
What is DEPENDENT VARIABLE
These two words are needed to accurately create a hypothesis.
What are the words IF and THEN?
This transfer of energy is through moving air or liquids.
What is CONVECTION?
This is the energy of heat.
What is THERMAL ENERGY?
A battery-operated fan is an example of which energy transformation?
What is CHEMICAL > MECHANICAL ?
A student investigates whether the height of a person affects how fast they can run. Identify the independent variable.
DOUBLE POINTS IF YOU CAN IDENTIFY THE CONSTANTS.
What is HEIGHT OF THE PERSON
A scientist suggests that students who attend school everyday will get a 90 or higher on their unit test. Provide an accurate hypothesis for this suggestion.
What is "IF STUDENTS ATTEND SCHOOL EVERYDAY, THEN THEY WILL GET A 90 OR HIGHER ON THEIR UNIT TEST."
This transfer of energy is transferred without contact. Instead, it is transferred in the form of waves.
What is RADIATION?
This is the sum of potential and kinetic energy combined.
What is MECHANICAL ENERGY?
A toaster is an example of which type of energy transformation?
A student investigated which color flower attracts the most bees. Identify the dependent variable.
DOUBLE POINTS IF YOU CAN IDENTIFY THE CONSTANT(S)
What is AMOUNT OF BEES
A scientist suggests that eating popcorn will help people stay awake during a movie. Identify the independent variable in this scenario.
DOUBLE POINTS IF YOU CAN IDENTIFY THE CONSTANT(S).
What is EATING POPCORN?
The hot air from a blow dryer rises and cools down as it sinks. This is an example of which energy transfer?
What is CONVECTION?
This is the energy produced by light or electromagnetic sources.
What is RADIANT ENERGY?
Playing the violin is an example of which energy transformation?
What is MECHANICAL > SOUND ?
A scientist is trying to investigate if the temperature of water has an effect on how well the shirt will clean. Identify the constant.
DOUBLE POINTS IF YOU CAN IDENTIFY THE CONSTANT(S).
What is BRAND OF DETERGENT
A bug repellent is sprayed on one arm. The other arm is not sprayed. The number of bug bites are then recorded after two hours. Identify the dependent variable.
DOUBLE POINTS IF YOU CAN IDENTIFY THE CONSTANT(S)
What is NUMBER OF BUG BITES?
A spoon gets hot after you stir a cup of coffee. This is an example of which energy transfer?
What is CONDUCTION?
This is the energy of flowing electric currents.
What is ELECTRICAL ENERGY?
A plant going through photosynthesis is an example of which energy transformation?
What is RADIANT > CHEMICAL ?
