Unit 2: Identifying Matter
Lab/Whiteboard Expectations Lab
The purpose of this lab is to familiarize you with experimenting and whiteboarding in chemistry.
The majority of labs will be very similar to this lab in terms of format. You will not be given a detailed
list of steps to follow. You will, however, be given a basic overview of the lab and made aware of any
special items. Because you will be tested on the concepts and techniques developed during labs, it is
critical to keep thorough and organized notes. An example of notes for this lab has been included.
You should follow a similar format for all other labs.
Mass and Change Labs
The following six labs will help us identify and understand matter:
1. Clumped/Separate Steel Wool
4. Solid/Dissolved Alka-Seltzer
2. Ice/Liquid Water
5. Burnt Steel Wool
3. Solid/Dissolved Sugar
6. Solid from Liquids
After completing all the labs, form a hypothesis to explain all of your observations about mass.
U2 EP1
Conservation of Mass Presentation
Volume Lab
Now that you have a grasp of mass, you can learn about volume. In this lab, you will investigate the
relationship between volume measured with a ruler and volume measured with a graduated cylinder.
Mass and Volume Lab
With mass and volume under your belt, investigate how these two quantities of matter are related.
U2 EP2
Density of a Gas Lab
How does the density of a gas compare with a liquid or solid? What must be true about the particles
that make up a gas? What about the particles in a liquid or solid?
Thickness of Aluminum Foil Lab
Combine your understanding of mass and volume with your mastery of math and determine the
thickness of aluminum foil. If you have time, compare how heavy-duty foil measures up with regular?
