During your WebQuest, you have learned a lot about chemical and physical changes, yet there is so much more to learn. For example, matter is NEVER destroyed or created during a change. The particles of one substance may rearrange, but the same number of particles that exist before the change exist after the change.

Other concepts definitely relate with the idea of Physical and Chemical Properties.

Go explore the idea of conservation of matter.

In addition, you may find it interesting that there are ways to change the rate of a chemical reaction. It can either be sped up or slowed down. Concentration, surface area, catalysts, and temperature are four ways that affect the rate of a chemical reaction. Click on the following link for investigations on reaction rate.
