Here is the text we read in class for properties of water:
properties of water

Here are the Prompts for taking notes on the properties of water:Read about the properties of water from your handout.  As you read, take notes by describing the following properties and describing why it is important to life functions:  

1.Water is cohesive

2.Water is adhesive

3.Water is the universal solvent

4.Water density changes with its state of matter

After you have taken notes......watch the video about the properties of water.

Here is a video describing how to balance equations

Balancing chemical equations

Here are two practice sites for balancing equations

The first site:  navigate down the left hand side to run through videos, examples until you reach the "balancing chemical equations tab" which allows you to practice.
