Experimental Design
This is the group in an experiment that does not receive the treatment and is used as a benchmark.
what is the control group
This is the part of an experiment where you change something to see what happens.
What is the independent variable?
This state of matter has a definite shape and volume.
What is a solid?
This state of matter has particles that are tightly packed and vibrate in place.
What is solid?
This process occurs when ice turns into water
What is melting?
This variable is manipulated by the researcher to observe its effect on the dependent variable.
What is the independent variable?
This is the main goal of doing an experiment, which is to find out if your guess about what will happen is correct.
What is testing a hypothesis?
his is the state of matter in which particles are far apart and move randomly, having no definite shape or volume
what is a gas?
In this state of matter, particles can flow past each other but remain close together.
What is liquid?
This process happens when water boils and turns it into steam
What is evaporation/ boiling?
This type of variable is measured in an experiment and is affected by changes in the independent variable.
What is the dependent variable?
This is what you call doing an experiment more than once to make sure the results are the same.
What is repetition?
This is the process by which a liquid turns into a gas below its boiling point.
What is evaporation?
In this state, particles move freely and are far apart from each other.
What is gas?
This process occurs when steam cools and becomes water droplets.
What is condensation?
These are variables that are kept constant to prevent them from influencing the outcome of an experiment.
What are controlled variables?
This is the change of a substance from the solid to the gaseous state without becoming liquid.
What is sublimation?
This process happens when dry ice turns into carbon dioxide gas without becoming liquid first.
What is sublimation?
This is the main goal of doing an experiment, which is to find out if your guess about what will happen is correct.
What is a hypothesis?
The temperature above which a gas cannot be liquefied no matter how much pressure is applied.
What is critical temperature?
This process occurs when a gas turns directly into a solid, such as frost forming on a cold surface.
What is deposition?
