Introduction
Chemical change is any process in which one or more substances are changed into one or more different substances. In this webquest, you must use the sources I have provided to discover more information on this topic.
Task
The desired outcome of this webquest has four elements:
- A t-chart comparing chemical change to physical change
- A bulleted list of evidence that would tell you if a chemical change took place
- A sentence or two stating the two major chemical properties a substance can have
- A bulleted list of 3-5 examples of chemical change
Process
Here are five links to sources that contain all the information you will need for this webquest.

The sum of the numbers in the bottom row is out of sixteen. Multiply it by 6 to get a score out of 96. The name is worth four points, so add the name to this score (if the name was included) to get a score out of 100.
Conclusion
Chemical change and chemical properties are awesome! Still don't agree, even after doing the webquest? Check out this cool chemical property of flour.
