Density and Rate of change

100

Describe density

the degree of compactness of a substance

200

How does density affect an objects ability to float on water? 

more dense than water = object sinks

less dense than water= object floats

300

Calculate the density of the object given the following measurements. 

mass= 2g Volume= 1 cm³

2 g/cm³

400

Calculate the density of the object given the following measurements. 

Density= 10 g/cm³         volume=2 cm³

20 g

500

What did Archimedes shout after discovering how to find the density of the king's crown? 

Eureka!!!

Greek for "I've found it" 

We love our ESRT
