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.
What’s Trending with the Elements?
This resource, aligned with Chemistry TEKS (5)(C), provides alternative or additional tier-one learning options for students using the periodic table to identify and explain trends.
Learners compare a variety of prokaryotes and eukaryotes to determine similarities and differences among and between them.
Monohybrid and Dihybrid Crosses
Learners calculate the probability of genotypic inheritance and phenotypic expression using mono- and dihybrid crosses.
Mechanisms of Evolution Beyond Natural Selection
Learners analyze and evaluate the effects of other evolutionary mechanisms.
Evidence for Evolution
Learners analyze and evaluate how evidence of common ancestry among groups is provided by the fossil record, biogeography, and homologies, including anatomical, molecular, and developmental.
The learner explores the structure and function of the nucleic acids and enzymes important to the process of synthesizing proteins.
6.08 Bonus Video: Law of Sines—The Ambiguous Case
The Law of Sines can be used to solve for sides and angles of oblique triangles. However, in some cases more than one triangle may satisfy the given conditions. We refer to this as an ambiguous case.
Covalent Bonding: Electron Dot Diagrams
Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).
Heat to Go
This resource provides alternative or additional tier-one learning options for students learning about heat transfer, Chemistry TEKS (11)(B).
Celsius 4-1-1: All About Thermal Energy
This resource supports Chemistry TEKS (11)(A).

5.02 Linear and Angular Velocity
In this video, students will learn about angular and linear velocity and how each relates to unit conversions.
5.03 Trigonometric Ratios
In this video, we will define the trigonometric ratios in terms of the sides of a right triangle.
5.04 Trigonometric Angles and the Unit Circle
In this video, students will learn special angles and the unit circle, and learn how to apply them.
5.05 Graphs of Sine and Cosine
In this video, students will learn how to graph sine and cosine and how to interpret graphs of sine and cosine.
5.06 Graphs of Secant and Cosecant
In this video, students will learn how to graph and interpret graphs of secant and cosecant, and how secant and cosecant relate to sine and cosine.
5.07 Graphs of Tangent and Cotangent
In this video, students will learn how to graph and how to interpret graphs of tangent and cotangent.
5.08 Inverse Trigonometric Functions and Graphs
In this video, students will explore the relationship between trigonometric functions and their inverses.
11.01 The Bohr Model of the Atom
In this video, we will study Bohr atom, electron transitions, and the line spectrum.
