ASSIGNMENTS: 1) Make word graffiti for each of the five terms in bold below. The meaning of the term should be evident from the drawing of the word. If this doesn't make sense, just draw a picture to represent each term.      2) Write a summary of the information below in your journal. 3) Visit this website on mixtures http://www.harcourtschool.com/activity/mixture/mixture.html 4) TAKE QUIZ HERE: https://www.quizlab.com/secured/authenticate_limited.cfm Click on "single class login", and input classword (tewinkle(#ofclass): ex. if you are in period 2, your classword is tewinkle2, Your password is first letter of name and as much of last name as fits (ex: htangen).              Richard Feynman, a Nobel prize winner, once said:  All things are made of atoms—little particles that move around in perpetual (continual) motion attracting each other when they are a little distance apart, but repelling upon being squeezed into one another.    ** Atoms ** are the basic particle from which all elements are made. **Elements** are pure substances that cannot be broken down any further into other substances. So one atom of carbon is the smallest you can have a substance that acts like carbon. If you break open the atom, the particles no longer have the characteristics of the element. You can take atoms and/or elements and combine them together. Two or more ATOMS together is a **molecule**. Two or more ELEMENTS bonded together is a **compound**. The difference is that molecules can be made of atoms of the same element (ex: H-H), whereas compounds require at least two different elements (ex: O-H). Water (H-O-H) is both a molecule and a compound. Next, you can take two or more elements and/or compounds and mix them together (like making trail mix: not bonded together, but separate entities), and have a **mixture**. The word combining implies bonding. Atoms of different elements combine to form compounds; a com pound may, and usually does, have chemical characteristics and physical properties that are different from those of its constituent elements.
 * //All forms of matter are com//** **//posed of one or more of the elements. (//**Q. 46, 47, 48, 49, 50)
 * //Students know//** **//that compounds are formed by combining two or more different elements and that compounds have properties that are dif//** **//ferent from their constituent elements.//** (Q. 40, 41, 42, 43, 44, 45, 54)
