Sept. 13 – Matter and Density

Quiz on Tuesday!

Here's a list of topics that you should study for.

 - Identify and explain WHMIS symbols and HHPS symbols

 - Explain lab safety rules

 - Identify lab equipment

 - Determine the number of sig. dig.

 - Convert between scientific notation and standard notation

 - Convert between units

 - Calculate the slope of a graph

Please make sure to see me for extra help if you are unsure about any of these topics.  I will be available Monday after school.

Practice handouts:

• Metric Conversion Worksheet
• Metric Conversion Practice

UNIT 1: Chemistry

Learning Goals: Understand how to describe matter and density.

Success Criteria:

• You can define terms such as matter, mass, volume and density.
• You can solve problems involving calculation of density.

Have a look at this video: http://www.youtube.com/watch?v=-CDkJuo_LYs.

How do the layers of liquid stay separate?  What determines which liquid stays on top and which ones on the bottom?  The answer has to do with the density of each liquid.

Handouts:

• Matter
• Measuring Volume
• Density

We filled in the blanks for each handout.  First we defined what matter is and how to describe it.  Then we discussed how to calculate volume and finally we filled in the blanks on the density handout.  Here is the handout will all the blanks filled in:

• Density notes completed

I also showed you how to solve the problem at the bottom using the GRASS method.  I will expect you to use this method to solve problems from now on.

Homework:

• Use the practice handouts to study for the Quiz on Tuesday!
