An interactive applet and associated web page that demonstrate the alternate exterior angles that are formed where a transversal crosses two lines. The applets shows the two possible pairs of angles alternating when in animation mode. By dragging the three lines, it can be seen that the angles are congruent only when the lines are parallel. When not in animated mode, there is a button that alternates the two pairs of angles. The text on the page discusses the properties of the angle pairs both in the parallel and non-parallel cases. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Students today develop proficiency with many different algorithms for multiplication. This approach insures that each student will find a method that works effectively for him/her. Teachers model the different algorithms and encourage students to use and practice each method before selecting a favorite.

This study used an organizational socialization lens to examine factors influencing participants’ choice to pursue the principalship and an alternate administration certification program. Through an analysis of participants’ interviews, factors emerged from the codes that were compared with dimensions of a socialization framework. A key finding from this study is the intersection of socializing factors that influenced participants’ decisions to pursue the principalship and their decision to pursue an alternative preparation programs. This intersection impacted how these aspiring and current principals came to participate in the alternate preparation program.

Road deicers raise several environmental and cost concerns. In this activity students consider alternatives while investigating colligative properties.

Global temperatures continue to be affected by the combustion of fossil fuels and the subsequent release of carbon dioxide. This 3-week unit is designed to give 9th grade physical science or environmental science student an introduction to climate change, how humans are influencing it, and what efforts we can make to help limit or prevent it. Topics necessary for this unit include electricity, circuits, greenhouse gases, alternative energies, embodied energy, payback period, and life cycle assessments. This unit functions as a culminating project incorporating all of the topics listed above and challenges students to conduct research, engineer their own alternative energy solutions and prove their efficiency through calculation. Individually or in pairs students must pick an alternative energy, spend a day or more researching it, a day drawing a blueprint for it and creating a materials list, two or three days building model “power plants” to light 3 LEDs, and two to three days writing summary research papers. The quantitative analysis of their models (included in their research papers) and student’s ability to prove their models environmental superiority over fossil fuels will be weighted heavily.

Students are asked to explain what needs to be considered if alternative energy sources are to be used. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

This is a research project for an Environmental Geology class, in which each student selects or is assigned a type of alternative energy to investigate. The project culminates in a 10-15 minute class presentation with accompanying written abstract.

Is climate change real? Yes, it is! And technologies to reduce Greenhouse Gas (GHG) emissions are being developed. One type of technology that is imperative in the short run is biofuels; however, biofuels must meet specifications for gasoline, diesel, and jet fuel, or catastrophic damage could occur. This course will examine the chemistry of technologies of bio-based sources for power generation and transportation fuels. We'll consider various biomasses that can be utilized for fuel generation, understand the processes necessary for biomass processing, explore biorefining, and analyze how biofuels can be used in current fuel infrastructure.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Autophagy is an important cellular recycling process that degrades misfolded proteins and damaged organelles. In typical (“canonical”) autophagy, membranes derived from the endoplasmic reticulum surround damaged materials that need to be degraded, and the proteins Atg5 and Atg7 help form specialized digestion compartments (autophagosomes), but another type of autophagy, called alternative autophagy, was recently discovered. In alternative autophagy, the membranes that envelop the damaged materials are derived from the trans-Golgi membrane, and Atg5 and Atg7 do not participate in autophagosome formation. Alternative autophagy seems to be activated primarily under conditions of cell stress, and it plays roles in many diseases, such as heart disease, neurodegenerative disease, cancer, inflammatory bowel disease, and bacterial infection..."

Alternative futures studies are a valuable yet resource-intensive way in which environmental scientists try to conduct informed debates about policies for specific geographic regions. These studies require modeling what the future would look like if different stakeholder groups had their way. The modeling is carried out by applying historical trend data to future projections that are rooted in the preferences of the different groups. Alternative future studies can be controversial due to the limitations of modeling and to the extent to which the models represent fully the different possible scenarios. Yet, they can be especially valuable for decision making about which areas in the region would be most appropriate and most acceptable for the applications of different policies such as development and restoration. Through a series of hands-on classroom activities that are the culmination of a variety of field trips, case studies, and analyses of GIS data about river systems and river restoration options, the students build deep understanding about what alternative futures studies entail and what are the applications of such studies to specific rivers in the Puget Sound area.

"The gut microbiome interacts intimately with its human host, both in health and in disease. A recent study examined how different states of the gut microbiome might be linked to varying degrees of disease in rats. Researchers exposed rats to different concentrations of dextran sodium sulfate (DSS), a polysaccharide known to induce human-like colitis. The effects on the intestinal microbiome over time were tracked by gene profiling. The results provide some of the first experimental evidence of “alternative states” in the rat intestinal ecosystem. These are distinct microbial profiles related to markers of disease. Importantly, these alternative states were found to be tied to both the host and microbiome, rather than one or the other. That led to a conceptual model of how host inflammatory status and microbiome status interact and how the whole ecosystem may slip into and out of different states of disease..."

"Since its appearance in late 2019, COVID-19 has caused well over one million deaths worldwide. Large-scale testing and contact tracing remain critical for controlling viral spread. Complying with the US CDC and WHO protocols for sample collection requires a ready supply of inexpensive swabs and collection reagents. Unfortunately, CDC-approved clinical-grade sampling supplies are expensive, and additionally, current methods prevent further analysis of the microbiome due to the presence of antibiotics in viral transport media. Researchers sought out new testing supplies in a recent study comparing five consumer-grade swabs and one clinical-grade swab. They found that using 95% ethanol instead of viral transfer media reduced RNase activity, preserving samples for microbiome analysis, and extracting directly from the swab head instead of the surrounding liquid resulted in 2-4x higher RNA recovery than the clinical standard..."
