Measuring Matter
This is defined as how much stuff is inside of an object.
Mass
Surface tension is defined as this
Elastic skin like layer formed on the surface of a liquid because liquid molecules come together and pull on each other.
A liquid freezes and a solid melts at this temperature in oF
32oF

This type of graph shows or compares different groups of things using rectangular bars
A bar graph
This is defined as mass x gravity
Weight
This is an example of a viscous liquid
