1. List the general properties of aqueous acids and bases.
2. Explain the difference between strong acids/bases and weak acids/bases and give examples.
This video provides a very short overview of the general properties of acids & bases:
This movie is older (from the 80s), and I include it b/c I used it a lot in my classroom -- it's a broad overview (about 18 minutes) which is handy for starting the unit. A few of the animations are a little blurry.
This video is from 2009 (30 minutes) so it's a little more current -- it might be a useful review video as it addresses pH and Bronsted-Lowry theory more in depth:
This video is a brief overview of strong vs. weak acids & bases:
I have such a lab in my lab book "Chemistry on a Budget" which tests the presence of acid or base in common household substances, and it shows how to prepare indicators out of fruits and vegetables.
Check out my lab book "Chemistry on a Budget" at amazon.com:
Each lab is presented with two possible report formats -- both labs use the same procedure page but each has a different conclusion page -- 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!
The National Science Teacher Association (NSTA ) annual conference was this past week in Boston, Massachusetts. If you attended the convention, please write me about it!
I have a few links listed under Teaching Resources that could be very useful -- if you haven't checked it out, the link is at the top of this page!
*I'd love to hear from you! Your feedback would really help me to focus on your needs. You might be having a school vacation soon (spring breaks are around this time) -- take advantage of the time and write me about your classroom experiences! There should be a "Contact" form below, or click on the "Contact" tab on the top right of this page.
Have a good rest of the week!
