45-45-90 Triangles
To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.
Mendelian Genetics Using Monohybrids
Students will work collaboratively through a fictitious, real-world scenario to determine the probability of each breeding pair of dogs producing offspring with the desired trait for a fictitious client.

TEA AP® Physics 1: Algebra-Based

AP® Physics is the result of an effort to better serve teachers and students. The textbook focuses on the College Board’s AP® framework concepts and practices.
The AP® Physics curriculum framework outlines the two full-year physics courses AP® Physics 1: Algebra-Based and AP® Physics 2: Algebra-Based. These two courses focus on the big ideas typically included in the first and second semesters of an algebra-based, introductory college-level physics course. They provide students with the essential knowledge and skills required to support future advanced coursework in physics. The AP® Physics 1 curriculum includes mechanics, mechanical waves, sound, and electrostatics. The AP® Physics 2 curriculum focuses on thermodynamics, fluid statics, dynamics, electromagnetism, geometric and physical optics, quantum physics, atomic physics, and nuclear physics. AP® Science Practices emphasize inquiry-based learning and development of critical thinking and reasoning skills. Inquiry-based learning involves exploratory learning as a way to gain new knowledge. Students begin by making an observation regarding a given physics topic. Students then explore that topic using scientific methodology, as opposed to simply being told about it in lecture. In this way, students learn the content through self-discovery rather than memorization.
The AP® framework has identified seven major science practices, which are described using short phrases that include using representations and models to communicate information and solve problems, using mathematics appropriately, engaging in questioning, planning and implementing data collection strategies, analyzing and evaluating data, justifying scientific explanations, and connecting concepts. The AP® framework’s Learning Objectives merge content with one or more of the seven science practices that students should develop as they prepare for the AP® Physics exam. Each chapter of AP® Physics begins with a “Connection for AP® Courses” that explains how the content in the chapter sections align to the Big Ideas, Enduring Understandings, Essential Knowledge, and Learning Objectives of the AP® framework. These sections help students quickly and easily locate where components of the AP® framework are covered in the book, as well as clearly indicate material that, although interesting, exceeds the scope of the AP® framework. Content requirements for AP® Physics are prescribed in the College Board Publication Advanced Placement Course Description: Physics, published by The College Board (http://ritter.tea.state.tx.us/rules/tac/chapter112/ch112d.html#112.64) and (http://ritter.tea.state.tx.us/rules/tac/chapter112/ch112d.html#112.65).

Taxonomy Standards

Given examples, students will recognize the importance of taxonomy to the scientific community.
Taxonomy: Major Groups

Given illustrations or descriptions, students will determine the classification of organisms into domains and kingdoms.
Enzymes

Given illustrations or scenarios, the student will identify an enzyme and the outcome of its action.
Animal System Interactions

Given illustrations, descriptions, or scenarios, students will describe the interactions that occur among systems in humans.
Mechanisms of Genetics: Protein Synthesis

Given illustrations or partial DNA or mRNA sequences, students will identify the processes and purposes of transcription and translation.
Abiotic Cycles

Given scenarios, illustrations, or descriptions, the student will describe the flow of matter through carbon and nitrogen cycles and describe the consequences of disrupting these cycles.
Homeostasis: Ecological Systems

Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.
Biological Systems: System Organization

Given illustrations or descriptions, students will relate the levels of organization to each other and to the whole system.
Biological Systems: Homeostasis

Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.
Relationships Between Organisms: Food Chains, Webs, and Pyramids

Given illustrations, students will analyze the flow of matter and energy in food chains, food webs, and ecological pyramids.
Symbiosis

Given scenarios or illustrations, the student will determine the nature and type of relationship between organisms, including parasitism, commensalism, mutualism, and competition.
Organisms' Adaptations

Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.
Homeostasis—Succession

Given scenarios, illustrations, or descriptions, the student will identify the process of ecological succession and the impact that succession has on populations and species diversity.
Predict Monohybrid Crosses

Biology Kid2Kid videos present biology concepts taught to a student by a student. This resource contains videos that explain monohybrid crosses in both English and Spanish.
Cell Homeostasis: Osmosis

The focus of this resource is cell homeostasis and, more specifically, osmosis. Students investigate the concept through a virtual lab, recording and analyzing data, creating sketches to represent vocabulary, and discovering the role of aquaporins in water transport through the cell membrane.
