All Screwed Up: A Game of Nuts and Bolts Designed to Help Students Discover Chemical Kinetics
In the general chemistry curriculum, kinetics--the study of the rates of reactions--is often approached in a classical and somewhat mechanical sense (Zumdahl 2009; Tro 2011). Classroom discussions typically begin with a change in some reactant or product's...

Antarctica's Pine Island Glacier: A "Climate Canary"? Using Atmospheric and Oceanic Processes and the Poles to Teach the Climate System
Antarctica's Pine Island Glacier (PIG) is large and rapidly changing and flowing into the ocean as a floating ice shelf (above and Figure 1, p. 58). The PIG lies on the edge of the warming Antarctic Peninsula, the handle-shaped section of Antarctica...

Beaming You Up a Time Suck
In the sci-fi classic, Star Trek, teleportation is an everyday thing. But how much time would teleporting a human being really take? A group of physics students at the University of Leicester have done the calculations and published their paper,...
Bill's Box: A Simple and Effective Approach to Stoichiometry
Stoichiometry, the branch of chemistry dealing with the relative quantities of reactants and products in a chemical reaction, is challenging for students new to chemistry. This article describes an effective method of teaching stoichiometry to students...

Can We Mine Asteroids?
Some scientists believe asteroids could provide us with scarce resources. An upcoming NASA mission will explore the possibility. Asteroids--lumps of metals, rock, and dust--are the cosmic leftovers of the solar system's formation 4.5 billion years...
Career of the Month
Aerosol Scientist Aerosol scientists such as Melissa Lunden--shown at right working with team members in a kitchen test facility--study airborne nanoparticles, whether emitted by household cleaning sprays, automobile exhaust pipes, or chemical spills....
Chemistry Instruction in the Era of the NGSS
As I begin my 38th year of teaching chemistry, I have been curious to see how the Next Generation Science Standards (NGSS) (Achieve Inc. 2013) will impact my teaching practices and those of my colleagues. The NGSS establish performance expectations...
Designing Your Course like a Video Game
Ever been engrossed in a video game where you had to keep playing--just a little longer--to see what was around the corner? Gaming is serious business. In her book, Reality Is Broken, Jane McGonigal (2011) reports that nearly 200 million Americans...
Dietary Fats: Friend or Foe?
Obesity among teens is still a major problem (the American Medical Association labeled obesity a disease in June [Pollack 2013]), and many people expect teachers to be part of the solution. K-12 schools should play the biggest community role in...

From Cars to Creatures: Converting Analogies into Student-Centered Activities
Since many scientific concepts are abstract and not evident in day-to-day life, some students have difficulty in firmly grasping their meaning. For example, the rate of movement of lithospheric plates is difficult for students to understand because...

Good Ozone, Bad Ozone
One Free-Response Question (FRQ) on the Advanced Placement (AP) Environmental Science exam this spring addressed ozone (see "On the web"). Those knowledgeable about atmospheric chemistry might ask: "Stratospheric or tropospheric?" Well, the FRQ asked...
Grave Analysis: Shedding Light on Death
The day before the child's death 800 years ago in Ribe, Denmark, was full of suffering, because the 10-13 year old had been dosed with mercury to treat a severe illness. Chemist Kaare Lund Rasmussen from the University of Southern Denmark determined...

Bird Brains Predate Birds New research suggests that dinosaurs evolved the brainpower necessary to fly well before they actually took to the air as birds. Based on high-resolution x-ray computed tomographic (CT) scans, the study, published in Nature,...

Is That the Teacher?
New teachers enter the profession with countless different life experiences. While teachers of all ages can commiserate over the common challenges of teaching teenagers, younger teachers face a special set of difficulties. The novelty of being asked...
Ocean Plume Could Be Major Source of Iron
Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding, published in the journal Nature Geoscience, may challenge researchers' assumptions...
Pocket Frogs
By NimbleBit. Free. NimbleBit. San Diego, CA 2013. This "freemium" app (free but with inapp purchases) for Android and iOS devices has the fun of a simple game and just enough science to lead players to an untamable addiction to amphibians. It can...
