1. Look at your notes, text, or Internet to find out what these four terms mean: Physical Property, Chemical Property, Physical Change, Chemical Change 2. Find and copy 4 pictures to your : 1 showing a physical property, 1 showing a chemical property, 1 showing a physical change, 1 showing a chemical change. 3. Place the images on your wiki page under the heading "**ASSIGNMENT 1: Physical and Chemical Properties and Changes**" and include a 1-2 paragraph explanation like my example below.
 * **ASSIGNMENT 1: Physical and Chemical Properties and Changes**


 * Physical Property:** Characteristics of a substance that can be observed without changing the identity of the substances.
 * Chemical Property:** Properties that describe how a substance changes into other substances.
 * Physical Change:** Changes in the size,shape or state of matter; does not change the identity of the substance.
 * Chemical Change:** Change that a substances undergoes when it turns into a new substance.


 * ASSIGNMENT 1: Physical and Chemical Properties and Changes**


 * Physical Property**
 * Chemical Property**
 * Physical Change**
 * Chemical Change**
 * For the Physical Property I have a crystal. Crystal is an element of the earth. It dose not change into another substance.**
 * For the Chemical Property I have ice. Ice is a part of the earth. It dose change into another substance. It changes from ice to water as it melts.**
 * For the Physical Change I have the color changing of leaves. Leaves are apart of the earth. It changes physicaly, by itself. It has no help from anything once so ever.**
 * For the Chemical Change I have a lit match. To make fire you need to rub two certan things together to make heat and a spark. I changes into fire when you do that. That is why fire is a Chemical Change.**
 * A Formual:** ** CH4 + 2 O2 [[image:http://upload.wikimedia.org/math/8/3/e/83e37b7246fdfcb99b2754210ebeae27.png caption="rightarrow"]] CO2 + 2 H2O **


 * Inertia- the resistance of an object that changes the motion or rests. **
