While conducting an experiment, always remember to do this.
Collect data.
100
There are three main states of matter, gas, ___, and solid.
liquid
100
Energy is the ability to do this.
Work, or cause a change.
100
Electricity is the movement of this type of particle.
Electrons
100
This is an example what type of wave?
Transverse wave
200
Before you make a hypothesis, you need to read up on the subject, or...
Do research.
200
This form of energy causes matter to change states.
Thermal energy
200
Thermal energy can also be called this.
Heat
200
Every magnet is surrounded by this.
Magnetic field
200
On the electromagnetic spectrum, this type of wave has the lowest energy and the longest wavelength.
Radio waves
300
This is the variable that the scientist changes during the experiment.
Independent variable
300
When thermal energy increases, the particles in matter ____
move faster.
300
The law of conservation of energy says this about why energy transformations happen.
Energy cannot be created or destroyed.
300
An electromagnet is an example of this.
Temporary magnet
300
Radio waves and another type of electromagnetic wave are used for telecommunications. Name that EM wave.
microwaves
400
This is the variable that is unknown. It's what the scientist is testing for.
Dependent variable
400
When the curve is horizontal, the temperature is ___.
Constant. It doesn't change.
400
The energy transformation that happen at a solar power plant is:
Radiant energy --> electric energy
400
You can do this to make an electromagnet stronger.
Wrap more wire around it's core.
OR
Use a stronger power source.
400
This is the main reason why digital signals are preferred over analog signals.
Digital signals have better quality and less interference than analog signals.
500
This is the variable that never changes during the experiment.
Control variable
500
The freezing point is the same temperature as this other vocabulary term.
Melting point

The energy transformation that happen when you play the violin is:
mechanical energy --> sound energy
500
We use electromagnets everyday to make life easier. An example of this is in transportation. Can you name one example?
Maglev trains OR Metro trains OR electric motors

What does sampling mean?
Sampling describes changing small parts of analog signals into digital signals.
