Many of you are returned from vacation. Welcome back!
Most school budgets are depleted for the 2015-2016 class year. The book Chemistry on a Budget contains inexpensive chemistry labs that could be useful. You can buy this lab book for $23 at amazon.com or lulu.com. Check it out!

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.
It will take a week or so to get to you, so Order Now!
*Some of you have purchased my lab book – be sure to check out Page 141 !
A current research development is a Metal Foam Armour that, combined with Kevlar, is strong enough to stop a bullet.
“Kevlar is the best-known brand for bulletproof vests and is top-rated on the National Institute of Justice (NIJ) standard for its bullet-stopping capability… It stops bullets because of its ultra-high molecular weight, meaning it has very long strands of molecules that essentially entangle the bullet as it enters.”

[BTW, this link has two videos to better explain and demonstrate this technology.]
“Composite metal foams (CMFs) are tough enough to turn an armor-piercing bullet into dust on impact. Given that these foams are also lighter than metal plating, the material has obvious implications for creating new types of body and vehicle armor – and that's just the beginning of its potential uses.“

“Afsaneh Rabiei, a professor of mechanical and aerospace engineering at NC State, has spent years developing CMFs and investigating their unusual properties…there are many applications that require a material to be more than just incredibly light and strong. For example, applications from space exploration to shipping nuclear waste require a material to be not only light and strong, but also capable of withstanding extremely high temperatures and blocking radiation.”
Here is another Extra Credit opportunity for Student Research or a brief Homework assignment for your students to read and summarize. Students are always asking “What does this have to do with me?” Here is an example of a real world development with several possible applications.
*Remember, this Blog contains several entries that would be helpful to your chemistry classroom. Remember, you can check out the Topic List to help you to find past Blog entries.
Also, Write To Me about your successes, challenges, or questions in the Chemistry Classroom.
Remember, buying a copy of the lab book Chemistry on a Budget can be very useful to your Chemistry classroom with labs and class article ideas.
Have a great week!
