Density, Mass, and Volume videos

1. If something is able to float we say that it is _______.
2. How is it possible for a very heavy cruise ship to float?

1. Write a brief summary of Archimedes' Principle.

Super Fun Investigation!!!

Make a density tower!!!  Watch the videos below and make your own to explore the concept of density.  

Take a picture of it, write down your observations and inferences, and you get two science article passes!!

Watch the videos on density then answer the following questions.

1) Describe density in your own words.  Make up your own definition of density.
2) Compare/Contrast the molecules in an object that is very dense with the molecules in an object that has a low density.  Draw a picture of the two objects and their molecules. 
3)  mass = 4.4 g  volume = 2.2 mL  density = ?
4) An object has mass of 450 g and a volume of 150 cm3, calculate its density.

5) a. Watch the video on measuring matter.

b. Take the review quiz to assess your knowledge.

Density = Mass/Volume

Mass is the measure of matter. Everything has mass. The bigger of the object, the more mass it has.

We measure the mass of an object with a triple beam balance.

Volume is the amount of space occupied by an object measured in three dimensions, expressed in cubic units.

The volume of an object can be measured with a graduated cylinder. 

Density  is a measure of how much mass is contained in a given unit volume (density = mass/volume). It is usually expressed in kg/m^3. Put simply, if mass is a measure of how much 'stuff' there is in an object, density is a measure of how tightly that 'stuff' is packed together.
