What is density?
This is how much mass is packed into a particular volume
State the density of water
State the SI unit for density
If an object floats in water what does this mean?
The object is less dense than the liquid
If an object sinks in water what does this mean?
The object is more dense than the liquid
What is a random error?
This causes specific readings to be too high or too low
This is caused by taking a measurement the wrong way
To avoid random errors, an average of the data should be taken
What is a systematic error?
This causes all the readings to be above or below the right value
What is a zero error?
This is a type of systematic error
It happens when an instrument has not been set to zero
What is a parallax error?
This is when a person takes a reading when looking at an angle
