An interactive applet and associated web page that demonstrate the three types of triangle: acute, obtuse and right. The applet shows a triangle that is initially acute (all angles less then 90 degrees) which the user can reshape by dragging any vertex. There is a message changes in real time while the triangle is being dragged that tells if the triangle is an acute, right or obtuse triangle and gives the reason why. By experimenting with the triangle student can develop an intuitive sense of the difference between these three classes of triangle. Applet can be enlarged to full screen size for use with a classroom projector.

This website hosts many examples of poetry from the jahiliyyah period to the present in an attempt to create a comprehensive diwan of Arabic poetry. Some poems have an audio component. Users can browse poetry by time period, by audio file, by author's name, or by custom search. The website is also in English and there are many poems that have been translated into English, although some poems that are on the website in English are not on the website in Arabic and vice versa. Users can submit poetry to the website via a submission system.

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:

"Chemotherapy failure is a devastating problem that frequently results from cancer multidrug resistance (MDR). MDR is often due to overexpression of proteins called ABC transporters, which can pump chemotherapy drugs out of cancer cells. However, there are currently no effective treatments for MDR. A new study tested whether adagrasib (MRTX849), a promising anticancer drug targeting a mutant KRAS protein, can help fight MDR in cancer cell lines overexpressing the ABC transporter ABCB1 and in mice with ABCB1-overexpressing tumors. Both in vitro and in vivo, adagrasib increased the anticancer efficacy of conventional chemotherapy drugs. Adagrasib did not change the expression level or location of ABCB1 in the cells to exert its MDR- reversing effects. Rather, it suppressed the ability of ABCB1 to pump the drugs out of the cancer cells, likely by preventing binding of the energy molecule ATP, which normally powers the transporter’s pumping action..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

OER Fundamentals are invited to remix this course planning template to design and share their OER project plans, course information and syllabus, and reflection.

Adapt is an online homework system that exists within the LibreTexts platform. Instructors can create courses and assignments for students. Course shells for preparatory chemistry, general chemistry, analytical chemistry, and organic chemistry are available in the commons area.

This learning pathway provides a quick and simple solution to adapting open content for new purposes.

This collection provides practical approaches and design ideas that can be easily implemented in tertiary education. If you’re looking for inspiration on how to use technology for teaching, you’re in the right place.

This is a template for lessons developed by the San Francisco Unified School District SLANT Cohort. (Replace this text with a short description of your SLANT-inspired lesson. Then add learning goals, keywords, standards alignments, subjects, and grades in their respective fields.)

I have added an extension for students to explore Ekphrastic Poetry.

A reference for adapting or revising an open textbook

Short Description:
The Adaptation Guide is a practical reference about how to customize — or adapt — an open textbook so that it better fits your needs in the classroom and elsewhere. This guide defines the term adaptation and discusses reasons for revising a book, why this is possible with an open textbook, and the challenges involved.

This activity is a brief introduction to adaptations as the group observes a live organism together. Adaptations are inheritable structures and behaviors that help a group of organisms survive in their habitat. Students start out observing an organisms’ structures, trying to figure which might help it survive in its habitat and which are inheritable. Then, they do the same with behaviors: attempting to figure out which ones are behavioral adaptations. To build understanding of a complex concept like adaptations, students need multiple exposures to it, which is why this activity should be followed by other adaptations-focused activities.

An alternative introduction to the chapter "Adapting and Living Together" - explained with Vamipres! It sits within the Ecology and Environment topic of the virtual school GCSE Biology. Teachers can choose which engagement video is better for their own uses and students.

Learn about how organisms adapt to their habitats. This video is part of The Virtual School's "Adapting and Living Together" chapter within our Ecology and Environment topic.

Deer mice live in many different habitats across North America. In each subpopulation, their fur coloring is a good match to their habitat. How did this come to be? Students run simulated experiments controlling habitat, predators, and displays of data. An optional datasheet can be used to structure quantitative work. The activity includes suggested questions for students to investigate, with particular attention to how the adaptation occurs solely at the population level, while natural selection operates on individuals.
