You may have received gift cards or cash for the holiday. Remember that you can buy my lab book "Chemistry on a Budget" for $20.56 at amazon.com or $23 at lulu.com. It will take a few weeks to get to you, so order now!
This book contains 13 labs using consumable materials purchased from local stores. There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
On January 6, 2015, there was a National Public Radio (NPR) article titled “How Anglers are Learning to Save Fish that get ‘The Bends’ ” about a catch & release program for deep sea fish. Because of the change in atmospheric pressure for the fish, they appear dead when caught, but they are not. You can read this article, or listen to it at:
To listen to the story, click on “Listen to the Story” and then on “How Anglers are Learning to Save Fish that get ‘The Bends’ ” in the box at the right.
I have discussed atmospheric pressure previously in a post titled “Boyle's Law” posted on 01/25/2014. This is another example of a real life situation demonstrating the inverse pressure-volume relationship of the particles making up a gas. I recommend discussing Kinetic Molecular Theory as an image for students to remember.
This written article, or the radio broadcast, could be assigned as a homework assignment for students to summarize or to research further.
Another assignment could be for students to list five facts from the article; however, there is a temptation to “cut and paste”, so you may require a handwritten assignment to avoid that possibility.
Students are always searching for Extra Credit opportunities, so you could use this article as an option.
