SciShow: 5 Groundbreaking Women in Engineering
No full textCouched between International Day of Women and Girls in Science (February 11) and International Women's Day (March 8), now is an excellent time to recognize the role of women in engineering with this episode of SciShow; as host Hank Green notes, "we really can't talk about women in STEM enough." In this brief video, viewers are introduced to five stellar women in engineering. Many readers are relying on WiFi to read this, and in part, people have Hedy Lamarr to thank for this ability. Lamarr, who received recognition for her work as an actress, was also responsible for strides in the realm of "frequency hopping spread spectrum," a signal system embedded in modern WiFi security. Adventure aficionados can thank Olive Wetzel Dennis for her work to "set a new standard for comfortable travel." Annie Easley was a key member of NASA's computing team, and her coding work built a foundation for today's hybrid car batteries. Lynn Conway is a scholar and social activist responsible for microchip design engineering that "kickstarted" current computers and cell phones. Finally, Treena Livingston Arinzeh is moving modern medicine forward with her stem cell research, and she is multiplying her impact by mentoring future engineers.

NOVA: Killer Volcanos
No full textWhen a team of archeologists uncovered a mass grave in East London in the 1990s, they initially hypothesized that it must have been a burial site of victims of the plague. However, radiocarbon testing revealed that the skeletons dated from sometime around 1250 CE, a century before the plague was introduced to Europe. So what happened? Through examining a number of historic manuscripts, archeologist Don Walker discovered that England had experienced a famine, caused by unseasonably frigid weather. In the year 1258 this famine, which killed no fewer than 30% of London's population, was likely caused by a volcanic eruption. This recent episode of PBS's NOVA, which aired on October 25, 2017, explores the science behind how volcanic eruptions impact global climate. This episode includes a consideration of the Mount Laki eruptions of 1783 and 1784, the Mount Tambora eruption of 1815, and the Mount Pinatubo eruption of 1991. Interested viewers can watch the full episode and check out a few related resources
Algebrarules.com
No full textThe self-proclaimed "autodidact math enthusiasts" behind Algebrarules.com write that they were "looking for all the rules of basic algebra presented consistently in one place" but couldn't find one. So they created Algebrarules.com, a sleek and easily browsable online resource for rules of arithmatic, exponents, and radicals. Visitors can browse for rules in these categories by selecting tabs that appear on the bottom of the browser. A Glossery is also available to help math students remember the difference between the divisor and the dividend and look up a number of other terms. Each rule on this website is accompanied by a written explanation and an example. The simplicty and user-friendliness of Algebrarules.com make it an ideal resource to incorporate into the classroom to encourage student independence and collaborative problem solving. Algbebrarules.com may also appeal to anyone looking for help completing assignments outside the classroom or studying for a standardized test
Dolphin Deaths: A Case Study in Environmental Toxicology
No full textThe National Center for Case Study Teaching in Science, which is housed at the University of Buffalo, is a National Science Foundation-sponsored, award-winning program that brings together various peer-reviewed case studies in order to enliven science education at the secondary and university levels. This particular case concerns an "unusual mortality event" (UME) of dolphins on the East Coast of the United States in the year 2013. The case study follows a journalist and four scientists attempting to solve the mystery. It then puts students in the role of investigators, asking them to read, compare, and interpret various explanations of the events, in the process learning the scientific and social aspects that likely intersected to cause the dolphin deaths. The entire case may be downloaded for free as a PDF. Teaching Notes and Answer Keys are also available
Science in the Classroom
No full textScience in the Classroom is an excellent resource for high school teachers and university professors who want to integrate the latest breaking research into their lesson plans. The project consists of a team of editors from the world-renowned journal Science, who work with an advisory board of scientists and science teachers to produce content designed for the classroom. On the site, readers may click on either High School or University to choose their target audience. Topics may be divided into Physical or Biological sciences (or choose âAnyâ to peruse all articles). Click on an article to read the editorâs introduction and annotations. Discussion questions are listed throughout. In addition, each article is accompanied by Activities and Teaching Resources, which can be downloaded as PDF files
Vox: Common Core math, explained in 3 minutes
No full textThe Scout Report doesn't usually review three-minute videos, but this one from Vox is worth it. First, because the video itself explains in sharp detail the seemingly incomprehensible pedagogy behind the "new math" that the Common Core utilizes to help students draw logical conclusions about the underlying principles of mathematics. And second, because the accompanying article, with its yellow "Launch Cards," provides a great overview of the common core and related topics. There are 18 cards, each dedicated to a different aspect of the Common Core. Topics include answers to such mysteries as, What is the Common Core? as well as who created it, what problems it's trying to solve, what is the federal governments role, and other intriguing answers
Uncertainty Measurements and the Wavelength of Light
No full textThis lab, presented by the National Nanotechnology Infrastructure Network, teaches students how to measure the wavelength of a laser. Furthermore, students will calculate the uncertainty in their measurement as it is "critical to have accurate measurements on the nanoscale." A Teacher's Preparatory Guide and Student Worksheet are provided that give detailed guidance for completing the lab. Â
How Dry am I? Exploring Biomimicry and Nanotechnology Lesson
No full textThis inquiry lesson teaches students about the properties of materials, specifically they will learn about superhydrophobic coated materials in contrast to uncoated materials. This contains a teacher's preparatory guide with lesson diagrams, pictures, material lists, and detailed procedures. Additionally, there is a student work sheet to guide students through preparing and completing the lab. There is also a document containing scanning electron images of lotus and magnolia leaves that could be used in an instructional presentation
Introduction to Microscopes
No full textThis activity, from Hagerstown Community College, introduces students to some of the magnification tools used in the study of biology. Students will use hand lenses, dissecting microscopes, and compound microscopes to investigate and identify specimens and compare the various levels of magnification provided by the microscopes. The lesson includes activity directions as well as an activity worksheet for students
Let's Talk Science
No full textAccording to a Carnegie Foundation commission of researchers, the growth of contemporary economies is reliant on STEM (Science, Technology, Engineering, and Math) workers. However, the U.S. has consistently fallen behind in math and science education. This site from Canadian nonprofit Letâs Talk Science provides an overview of some fresh ideas about how to get kids interested in STEM. Readers may want to start with the Programs & Resources section, where they will find gems such as Curiocity, IdeaPark, and other web-based programs for educators who are looking for fresh ways to spark interest in STEM subjects with their students. The Research & Publications tab links to empirical data on studentsâ attitudes toward science and the effect of Letâs Talk Science on those attitudes. There are also activities and media resources available on the site
