A Good Day's Work
One of our most important tasks as science educators is to encourage students to consider careers in science, technology, engineering, and mathematics (STEM). Both our nation and world face increasingly complex and challenging problems that require...
Antibacterial in Your Toothpaste May Combat Severe Lung Disease
A common antibacterial substance found in toothpaste may combat life-threatening diseases such as cystic fibrosis, or CF, when combined with an already FDA-approved drug. Michigan State University researchers have found that when triclosan, a substance...
Astronomers Release Most Complete Ultraviolet-Light Survey of Nearby Galaxies
Capitalizing on the unparalleled sharpness and spectral range of NASA's Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies. The...
Audio Engineer
Audio engineers control microphones, mixing boards, speakers, and other technical equipment to help produce the desired sounds for recordings or live events. Their skills can be applied in a wide variety of industries and settings, ranging from film,...
Bow Waves to Sonic Booms
Waves are produced by vibrations, and their speed depends on the medium in which they travel. When the source of water waves or the source of sound waves in air travels faster than the waves produced, some interesting effects occur. Let's begin with...
Creative Assessment: Using RAFT Writing to Assess Students in a Course on Motion
The ideas we form about science concepts during our day-to-day lives are not always correct (are the bubbles in boiling water air, oxygen, hydrogen, heat, or water vapor?). One way to probe students' misconceptions about science during instruction...
DECODING CAREERS IN DNA: Genetic Coding Lesson Brings Computational Biology and STEM Careers to Life
This article describes how you can turn your class into a STEM exploration hub where students engage with real-life scientists, mathematicians, and engineers. Within this space, students have opportunities to connect Next Generation Science Standards--aligned...
How Do You Get Teens to Stop Cellphone Use While Driving? Survey Says, Show Them the Money
Teens who admit to texting while driving may be convinced to reduce risky cellphone use behind the wheel when presented with financial incentives such as auto-insurance apps that monitor driving behavior, according to a new survey conducted by researchers...
Map My Data
Visualization of data through charts and graphs has always been a step in the process that students use to understand and interpret data. Traditionally this involved students plotting data with graph paper or graphing software. Using Google Maps,...
Mediterranean Diet May Blunt Air Pollution's Ill Health Effects
Rich in antioxidants, the Mediterranean diet favors fruits, vegetables, whole grains, legumes, olive oils, fish and poultry over red meat and processed foods. Antioxidants are molecules that disarm oxidized and highly reactive molecules, or free radicals,...
On the Job: Job Shadowing and Internships Open Doors to STEM Careers
At 7:30 a.m., while some students are still in bed, others across Omaha, Nebraska, are checking in at veterinary clinics. There they observe animal surgeries and dental exams, assist with lab procedures, learn the basics of routine physical exams,...
Robotic Assembly of the World's Smallest House-Even a Mite Doesn't Fit through the Door!
A French nanorobotics team from the Femto-ST Institute in Besancon, France, assembled a new microrobotics system that pushes forward the frontiers of optical nanotechnologies. Combining several existing technologies, the [micro]Robotex nanofactory...
Scientists Analyze First Ancient Human DNA from Southeast Asia
The first whole-genome analyses of ancient human DNA from Southeast Asia reveal that there were at least three major waves of human migration into the region over the last 50,000 years. The research, published online May 17 in Science, complements...
US Poison Control Centers Receive 29 Calls per Day about Children Exposed to ADHD Medications
A new study conducted by the Center for Injury Research and Policy and the Central Ohio Poison Center at Nationwide Children's Hospital found that there were more than 156,000 calls to US Poison Control Centers regarding exposures to attention-deficit...
VIEW FROM THE TOP [AND BOTTOM] OF THE WORLD:Teaching Global Climate Change from a Polar Perspective
The consensus among climate scientists is that the Earth is experiencing human-caused global warming (Cook et al. 2016). Climate change is especially visible in the polar regions, where rising temperatures are melting ice and altering ecosystems. Knowledge...
Want to Help Your Child Succeed in School? Add Language to the Math, Reading Mix
Research shows that the more skills children bring with them to kindergarten--in basic math, reading, even friendship and cooperation--the more likely they will succeed in those same areas in school. Hence, "kindergarten readiness" is the goal of many...
Who TAGGEA the Bench? Five Spiraled Activities to Show the Importance of Interpreting Data
Understanding how scientific conclusions are drawn from data is central to learning about the nature of science. Many students struggle with aspects of reasoning from data, including identifying relationships among variables (Kanari and Millar 2004),...
