1. Describe the motion of particles of the three phases of matter according to Kinetic Molecular Theory.
2. Interpret information from a graph of Temperature vs. Time during the heating or cooling of a substance.
Here is a video briefly discussing the motion of the particles in the three phases of matter according to Kinetic Molecular Theory. It's a little longer than 4 minutes:
Here is a blank heating curve diagram that could be used for a lecture:
Here is a Powerpoint presentation that is a good overview, but uses some lab data:
Previously on 3/2/14, I posted a lab about the heating and cooling of paradichlorobenzene. I realize that you may not be able to "sacrifice" too many test tubes and thermometers to this lab.
Here is a lab experiment based on the heating curve of water (a much easier substance to acquire), starting with ice:
Here are two more water-based labs, but the set-ups are not illustrated:
If you have access to temperature probes (such as Vernier or PASCO), here are a couple of labs that might be useful:
This is a little longer, but it's a Vernier lab:
Here are more Worksheets for student practice of Heating/Cooling Curves.
This is very basic:
This worksheet is 3 pages:
This worksheet contains several graph images that could be used in your own worksheets as well:
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:
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 weekend!
