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.
