Interactive Bonding Resources from PBS

One of the resources we have vetted is an interactive slideshow from PBS on both ionic and covalent bonds.  Teachers using Modeling Instruction will find these resources elucidate a model of electron behavior which adds to the particle story of matter we have been telling throughout the year. 

Why I think I love Atomsmith...

I first stumbled upon Atomsmith at Chem Ed 2015. Totally loved the way you could pop up a number of molecules on the big screen and move them around. They had really cool stuff like showing and modeling phase changes with water. They demonstrated the ability to show quantum orbitals in which you can see all of the clouds combined and then separate the electron clouds into individual orbitals. I was all set to jump in feet first and then my heart sank...they had it on everything but chromebooks (which is what we use at my school). The presenter suggested that I contact the good people at Atomsmith. They have been working on an online version that runs on chromebooks.

Self-Healing Concrete

Typically we think that the wear and tear of automobiles on the roads causes concrete roads to deteriorate, eventually causing potholes and requiring the use of patching. Regular maintenance, like patching, gets expensive over time. If we were to zoom in on a microscopic level we’d see microscopic cracks that allow in water, salts, and ice. Since ice has the ability to expand, the tiny little cracks will become big noticeable cracks.

"Even Einstein Struggled: Effects of Learning about Great Scientists’ Struggles on High School Students’ Motivation to Learn Science"

           What motivates our students to excel in understanding chemistry? For some students, they would like to pursue a career in a science related field while others are extrinsically motivated for a particular grade or graduation credit.

"The Stress Test", by Dana Goodyear

Rivalries, intrigue, and fraud in the world of stem-cell research. This "inside story" from some of the most prestigious biochemistry laboratories in the world can provide grist for any course on ethics in modern science.

Toward roads that de-ice themselves

This year in the midwest United States, winter has been a fickle friend. I haven’t seen the same amount of snow or ice as in recent years, but I still made sure I was prepared for it at our home by stocking up on calcium chloride to use as a de-icer on my driveway and sidewalks.
