Algebra and Trigonometry 2e provides a comprehensive exploration of mathematical principles and meets scope and sequence requirements for a typical introductory algebra and trigonometry course. The modular approach and the richness of content ensure that the book addresses the needs of a variety of courses. Algebra and Trigonometry 2e offers a wealth of examples with detailed, conceptual explanations, building a strong foundation in the material before asking students to apply what they’ve learned.Attribution: This work "Algebra and Trigonometry, 2e" by Jay Abramson is licensed under a Creative Commons Attribution 4.0 International License, except where otherwise noted.  

Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.

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.

In the first of two sequential lessons, students create mobile apps that collect data from an Android device's accelerometer and then store that data to a database. This lesson provides practice with MIT's App Inventor software and culminates with students writing their own apps for measuring acceleration. In the second lesson, students are given an app for an Android device, which measures acceleration. They investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Then they use the data to create velocity vs. time graphs and approximate the maximum velocity of the device.

Animal welfare has been described as a complex, multi-faceted public policy issue which includes important scientific, ethical, and other dimensions. Improving our understanding of animal welfare, involves the fascinating study of animal behavior as well as the challenge of accessing the emotions of animals.

This is the On-Demand version of this course, which means you can start the course at any time and work through the course materials at your own pace. The materials and quizzes will always be available to you.

Astrobiology Survey is an introductory course on astrobiology. It takes a multi-disciplinary approach that unites the sciences and arts to study the three questions of "How does life begin and evolve?", "Does life exist elsewhere in the universe?" and "What is the future of life on Earth and beyond?"

In this activity, students will explore how the Law of Conservation of Energy (the First Law of Thermodynamics) applies to atoms, as well as the implications of heating or cooling a system. This activity focuses on potential energy and kinetic energy as well as energy conservation. The goal is to apply what is learned to both our human scale world and the world of atoms and molecules.

BPCC Open Campus - Math 097: Basic Mathematics is a review of basic mathematics skills. Here's what's covered: -fundamental numeral operations of addition, subtraction, multiplication division of whole numbers, fractions, and decimals -ratio and proportion -percent -systems of measurement -an introduction to geometry NOTE: Open Campus courses are non-credit reviews and tutorials and cannot be used to satisfy requirements in any curriculum at BPCC.

CK-12 Basic Physics - Second Edition updates CK-12 Basic Physics and is intended to be used as one small part of a multifaceted strategy to teach physics conceptually and mathematically.

This course is also intended to provide the student with a strong foundation for intermediate algebra and beyond. Upon successful completion of this course, you will be able to: simplify and solve linear equations and expressions including problems with absolute values and applications; solve linear inequalities; find equations of lines; and solve application problems; add, subtract, multiply, and divide various types of polynomials; factor polynomials, and simplify square roots; evaluate, simplify, multiply, divide, add, and subtract rational expressions, and solve basic applications of rational expressions. This free course may be completed online at any time. It has been developed through a partnership with the Washington State Board for Community and Technical Colleges; the Saylor Foundation has modified some WSBCTC materials. (Mathematics 001)

Student Biology Book covering the Biology Keystone Standards. Teacher feedback on student responses helpful.

Biology for AP® Courses covers the scope and sequence requirements of a typical two-semester Advanced Placement® biology course. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology for AP® Courses was designed to meet and exceed the requirements of the College Board’s AP® Biology framework while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP® curriculum and includes rich features that engage students in scientific practice and AP® test preparation; it also highlights careers and research opportunities in biological sciences.

In Bootstrap:Data Science, students form their own questions about the world around them, analyze data using multiple methods, and write a research paper about their findings. The module covers functions, looping and iteration, data visualization, linear regression, and more. Social studies, science, and business teachers can utilize this module to help students make inferences from data. Math teachers can use this module to introduce foundational concepts in statistics, and it is aligned to state and national standards.

The full OpenStax Biology course, together with digital exercises that are repeated in an efficient way to help you achieve lifelong mastery in the subject material.

Este Produto Educacional consiste em um caderno de sugestões de práticas pedagógicas a ser utilizado em atividades educacionais com objetivo de favorecer o ensino contextualizado das ciências ambientais a partir dos princípios biotecnológicos presentes nas Tecnologias Culturais Locais. O caderno de práticas pedagógicas interdisciplinares foi desenvolvido com o intuito de contribuir com uma ferramenta didática do processo educativo das ciências ambientais proporcionando conhecimentos ligados às habilidades propostas pela BNCC (BRASIL, 2017). A interdisciplinaridade relaciona várias disciplinas com o objetivo de enriquecer o conhecimento entre as mais diversas áreas e se justifica pela necessidade de se reorganizar e reagrupar os campos do saber para não perder a relevância e a significação dos problemas e a busca por soluções. Possibilita, também, a formação de um sujeito mais aberto, flexível, solidário, democrático e crítico. Mais além, reúne
estudos complementares de diversos especialistas em um contexto de estudo de âmbito mais coletivo.
