Things to know for the standard check tomorrow:
- Key terms, such as Matter, Element, Compound, and Mixture
- How can the components that make up compounds be separated? What about the components of mixtures?
- How many different types of substances are needed to make elements, compounds, and mixtures?
- What happens to the properties of substances when they form compounds? Do they remain the same, or are they different? What happens to the properties of substances when mixtures are formed?
- Examples of physical properties and chemical properties
- Examples of physical and chemical changes: For more practice on physical and chemical changes go to this site, where there are 20 changes you can identify as being physical or chemical.
- How can you illustrate what occurs in an ionic bond? Here is a video, if you need a refresher....
- How can you illustrate what occurs in a covalent bond? Here is another video. Feel free to view it if you're not sure how to draw covalent bonds.
Let me know if you have any questions on this stuff. As always, I hope that all of you do a great job on the standard check tomorrow. Can you believe that it is the end of the 1st Quarter already?
