Aerial Photos Change the Face of War
At first it looks like a moonscape: barren, pocked with craters, crisscrossed with deep grooves, with no apparent signs of life. On closer scrutiny, however, details emerge. The ghostly lines at the top become a stand of bare trees, the specks across...
Authentic Science Practices
Any education that focuses predominantly on the facts of science without developing an understanding of how those facts were established ... misrepresents science (NGSS Lead States 2013, Appendix F, p. 2). This issue showcases activities in which...
Average C[O.Sub.2] Levels Reach New High
The globally averaged concentration of carbon dioxide in the atmosphere reached 400 parts per million for the first time in 2015. It surged again to new records in 2016 on the back of the powerful El Nino event, according to the World Meteorological...
Call for Papers
The Science Teacher (TST) is seeking manuscripts of approximately 2,000 words that describe new and creative ideas for the secondary science classroom. Manuscripts should provide worthwhile ideas and practical help for teachers as they relate to the...

Cat Wars
Cat Wars By Peter P. Marra and Chris Santella. $24.95. I 212 pp. Princeton University Press. Princeton, NJ. 2016. ISBN: 9780691167411. [ILLUSTRATION OMITTED] Cat Wars describes scientific studies that link disappearing bird species to free-ranging...
Commentary
Proactive Leadership Reform in science education takes effort on multiple fronts. Science education is frequently cited as part of the answer to growing concerns over the United States' capacity for innovation and economic competitiveness. This...
Converting Thoughts to Text
What if a device could decode your thoughts into actual speech or written words? It could be a potential game-changer for those with speech pathologies and even more so for "locked-in" patients who lack any speech or motor function. "So instead...
Core Values: Students Study Sediment Cores to Learn about Climate in the Past
[ILLUSTRATION OMITTED] To paraphrase James Hutton, the 18th-century Scottish scientist dubbed the "father of geology," to understand the future we must understand the past (Hutton 1970). That's certainly true of climate change. Yet, students (and...

Developing the Knowledge Constructor
Our past two columns focused on the International Society for Technology in Education (ISTE) Empowered Learner standard and Digital Citizen standard, respectively. This month, we discuss the ISTE's Knowledge Constructor standard. When students become...

Energy Drinks and Alcohol a Dangerous Mix
Drinking highly caffeinated alcoholic beverages triggers changes in the adolescent brain similar to taking cocaine, and the consequences last into adulthood as an altered ability to deal with rewarding substances, according to a Purdue University study....
Focus on Physics
How E = m[c.sup.2] Helps Us Understand Nuclear Fission and Fusion Nuclear physics has an undeserved reputation for being tough for students. This article may reduce this "toughness" by showing how Einstein's familiar equation E = m[c.sup.2] relates...
Half of American Kids Spend Time near Guns
A survey of parents in Missouri and Illinois reveals that about half of the children in the families queried spent time in homes that have firearms. However, few parents reported talking about gun safety with their children's pediatricians. [ILLUSTRATION...

Health Wise
Keeping Track of Sugar Students should consume no more than 25 g (6 tsp.) of added sugar per day, recommends the American Heart Association (AHA 2016). "Added sugars contribute to a diet that is energy dense but nutrient poor, and increase risk...
How E = [Mc.Sub.2] Helps Us Understand Nuclear Fission and Fusion
Nuclear physics has an undeserved reputation for being tough for students. This article may reduce this "toughness" by showing how Einstein's familiar equation E = [mc.sup.2] relates to the reductions in mass and enormous releases of energy that occur...

Measuring C[O.Sub.2]: Students Learn Firsthand How Thawing Permafrost Adds to Global Warming
In 2016, global air and sea surface temperatures reached their highest levels for the January-through-June period since recordkeeping began in the 1800s. The Arctic is warming about twice as quickly as other regions on Earth due to human production...
