Properties
A state of matter with a definite shape and volume.
What is a solid?
This word describes the transition from liquid to solid.
What is freezing?
Particles move faster when this happens to them.
What is heating?
This temperature scale is based around the phase changes of water.
What is the Celsius scale?
This is a testable explanation or prediction
What is a hypothesis?
A state of matter that does not have a defined shape or volume.
What is a gas?
These words describe a substance that goes from one state of matter to another.
What is a phase change?
Particles are what makes up this kind of matter.
What is all matter everywhere?
This is what happens to the volume of a substance when it is heated.
This is the variable that the researcher changes on purpose to see what happens.
What is an independent variable?
A state of matter that has a defined volume but not shape.
What is a liquid?
This word describes the transition of a gas into a liquid.
What is condensation?
In this situation, particles will bounce off of each other and move apart.
What are particles in a gas?
When you cool an object, this word describes the change in volume that can be observed.
What is contraction?
These must all be kept the same in a scientific experiment in order to get useful data.
What are controlled variables?
This state's particles move away from each other to fill a room.
What is a gas?
This word describes the transition of a gas into a plasma.
What is ionization?
The particles in a plasma are different than a gas because of this.
What are electrons separating from the particles and freely flowing?
As you remove thermal energy from an object, the particles begin to do this.
What is slow down or move less?
This is what you measure to see its response to the researchers actions
What is a dependent variable?
This state of matter conducts electricity and responds to magnetic fields.
What is a plasma?
This word describes the transition of a plasma into a gas.
What is deionization?
In this unique substance, particles expand when cooled and contract when heated.
What is water?
What is plasma?
Your science fair project should contain meticulous notes in this document.
What is a logbook?
