Learning Goals:

• I can explain what density is.
• I know how the particles look in a low density substance and a high density substance.
• I know how to calculate the density using a table if the mass and volume are given.
• I know what the unit is for density.

Key words:

• Density
• Molecule

density

Density:

Density is how much matter is packed into a given area.

The different states of water are more dense, the colder the temperature. Think of the difference between steam, water and ice. 

Calculating density

Mimoun has 50 mL of a liquid that he places on the scale. The liquid has a

mass of 300 grams. What is the density of the liquid?

When calculating the density we need to know the mass of only 1 mL,

not 50 mL. We can put this information in a table to help us:

Mass	Volume
300 grams	50mL
? grams	1mL

You will get a worksheet from me (does not have to be in your lab journal)

We will do this together! 

Homework:

• Complete the exercises on page 18 & 20.
• Study the glossary of topic 1.3 in StudyGo
• Study your notes and the lessonups of the last 3 lessons.
• Next lesson will be a practice quiz.

Learning Goals:

• I can convert between different units in the metric system
• I know the names of the most common lab materials and what they are used for
• I know the lab safety rules and safety symbols
• I know where to find the different safety materials in the lab
