1. Login to www.mywebspiration.com and open the "Classification of Matter" file 2. Complete the activity using the directions found when you open the file. 3. Find a method for posting the completed concept map as a new assignment at the top of your wiki page (Note: there is more than one way to do this depending on the computer you are working on)
 * **ASSIGNMENT 2: Classification of Matter Flowchart**



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**
 * Note: each image is worth 3 points and each correct sentence is worth 2 points for a total of 20 points**.


 * NOTE: Below is an example to help guide you. However, you must come up with your own new creative idea, images, explanation.**
 * The color of the yorkie, the shape of its body, it being a solid, and the texture of its fur are all** physical properties **. A** physical property **is a characteristic you can see like color, phase, texture, shape, etc..**

(**The burning of the wood is an example of a** chemical change **.)**
 * The yorkie's bow is a** physical change **. The yorkie is still the same after the bow was put on. As long as the structure and balance is the same it's a** physical change.
 * The soot and sulfur from the fire is a** chemical property **. A** chemical property **is a change you see after a chemical change, it's a change that alters the original structure. It might change the phase of matter or change it completely.**


 * The fireworks are an example of a** chemical change **because inside the fireworks are magnesium and copper and when you let them off they explode. The magnesium and copper change chemically when they burst. A** chemical change **is when a substance changes into a new substance.**
