Variables
What do scientists do to not affect the result?
They try not to change other variables
Is sound through air matter?
Sound through air does not count as matter.
How does liquid density affect if the object sinks or floats?
The liquid density affects if the object sinks or floats because the density of the object may become lighter than the water's density
When something is hit.
What is Impact.
The number of waves per second?
What is Frequency.
What variable changes the independent variable?
the dependent variable
Is everything matter?
No, light and sound are not.
How do you find density?
mass/volume
The job something does?
What is Function.
What is the highest point of a wave?
What is the Crest.
Why do scientists need to decide if the independent variable is changed or not?
because data is determined by the relationship between the independent variable and the dependent variable.
how can you tell if something is matter
If it has mass and volume, it has matter
What does density really tell you?
It tells you the relationship between mass and volume.
When Scientist use their 5 senses to gather information..
What is Observation.
The tone of a note, higher or lower.
What is Pitch.
What is an independent variable?
A factor that is deliberately manipulated
Anything that has mass and takes up space is?
Matter
Will an object float if the density of the object is 1.1 and the water's density is 1.0?
No, the object will sink because 1.1 is greater than 1.0
The way something is made?
What is Structure.
How loud or quiet sound is...
What is VOLUME.
What determines data?
The independent variable and the dependent variable.
What does matter make?
Matter makes everything except light and sound
Does everything have density?
everything in the universe has density because everything is made up of matter
The smallest units of matter...
What is Atoms.
What is the height of a wave, from the midpoint to the crest or trough
What is Amplitude.
