LEQ: What physical properties of water
make it unique?
1. What is susceptibility?
2. What do we call a chemical that causes cancer?
3. What disease would you predict someone to
have if his mother drank alcohol when she was
pregnant?
4. What is one benefit of using pesticides?

2. Our Progress This Year:
Unit 1: Geologic Evolution
Unit 2: Chemistry
Unit 3: Hydrosphere
Unit 4: Cells
4. Today’s LEQ: What physical properties
of water make it unique?
By the end of today, you should be able to…
1. Describe buoyancy and surface tension
2. Explain the special qualities relating to water’s
density, specific heat, and solubility
6. Lab Procedures
1.Do not write on class sets
2.Follow all instructions every time
3.All work goes in your notebook
4.Teamwork
5.Assign Partner numbers
8. Colder water = denser water
The “skin” that covers
The upward water’s surface
push of water
molecules on a
substance Water is the
universal
Water heats solvent!
and cools very
slowly!
