I know you've got a 3-day weekend coming up so I decided to post early.
Years ago I had access to a Coronet video called "Elements, Compounds & Mixtures". Using that theme, here are some resources that might be useful.
This web-page has a 20-minute movie titled "Classification of Matter" :
http://video.nhptv.org/video/2365088982/?utm_source=BlogLinks&utm_medium=AutoBlog&utm_campaign=nhptv_video_portal
This movie is a good overview of the basic ideas of Element, Compound, Homogeneous Mixture and Heterogeneous Mixture. A worksheet could be produced to keep the students on task, students could be required to record 10 facts from the video, or simply to record notes from the video.
At 7:30 minutes, the narrator eats food with the lab projected in the background. He is making a point about salt, but remember: NEVER EAT OR DRINK IN THE LABORATORY!
Also, boiling a salt water mixture on a hot plate to dryness can lead to solid salt with water vapor trapped underneath that "pops" out, also called "bumping" -- this can spatter the salt out of the beaker, reducing results if the goal is to separate the mixture.
There's a handy chart summarizing the main ideas at 13:55 minutes. There is also a nice quiz identifying various substances, and then explanations of each substance. This makes the video a nice resource for sub plans (just in case). There is a quiz in the last 3 minutes -- the first few questions refer to another video -- then it is a handy review of what was just seen.
Here is a Powerpoint presentation about Elements, Compounds and Mictures that also provides a useful overview of various physical separation techniques:

This link contains several worksheets as well as a blank Periodic Table at the end:

Just a reminder, I have just added a Topic List to help you to find past Blog entries you're looking for. I hope it helps!
Buy my lab book "Chemistry on a Budget" -- it is available for $20 at amazon.com or $23 at lulu.com:
http://www.amazon.com/Chemistry-Budget-Marjorie-R-Heesemann/dp/0578129159/ref=sr_1_1?s=books&ie=UTF8&qid=1389410170&sr=1-1&keywords=chemistry+on+a+budget
http://www.lulu.com/shop/marjorie-r-heesemann/chemistry-on-a-budget/paperback/product-21217600.html
The book contains 13 labs that require consumable materials you can purchase at local stores.
Each lab is presented with two possible report formats -- both labs use the same procedure but each has a different conclusion -- one with 10 questions to be answered as a conclusion, the other with a full laboratory report required. This gives the teacher the option of what type of report is desired. Each version is designed to be just two pages. This way the teacher can photocopy just one 2-sided page per student (saves paper).
I hope your school year is going well! Write me to let me know about your triumphs, challenges and questions!
Have a great 3-day weekend!
