###
Protein Synthesis

The learner explores the structure and function of the nucleic acids and enzymes important to the process of synthesizing proteins.

###
Cell Comparisons

Learners compare a variety of prokaryotes and eukaryotes to determine similarities and differences among and between them.

###
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.

###
Energy and Matter in Cells

Learners compare changes in matter that take place during energy conversion processes such as photosynthesis and cellular respiration.

###
Energy and Matter in Ecosystems

Learners analyze food chains, webs, and pyramids to determine how energy flows and matter cycles through ecosystems.

###
The Role of Enzymes

Learners investigate the role of enzymes at the molecular level as well as through “real-world” applications.

###
Ecological Succession

Learners explore and describe how succession affects biodiversity by creating an island ecosystem in an interactive game.

###
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.

###
Objects in Motion

This resource provides flexible alternate or additional learning activities for students learning about the concepts of distance, speed, and acceleration. IPC TEKS (4)(A)

###
Using Logical Reasoning to Prove Conjectures about Circles

Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.

###
Creating Nets for Three-Dimensional Figures

Given nets for three-dimensional figures, the student will apply the formulas for the total and lateral surface area of three-dimensional figures to solve problems using appropriate units of measure.

###
Generalizing Geometric Properties of Ratios in Similar Figures

Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding angles.

###
Determining Area: Sectors of Circles

Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.

###
Making Conjectures About Circles and Segments

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties and relationships among the resulting segments.

###
Determining Area: Regular Polygons and Circles

The student will apply the formula for the area of regular polygons to solve problems.

###
Making Conjectures About Circles and Angles

Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties of and relationships among the resulting angles.

###
Solving Problems With Similar Figures

Given problem situations involving similar figures, the student will use ratios to solve the problems.

###
Genetic Mutations

This resource uses video, animation, text, and web-based interactives to help students identify changes in DNA and evaluate the effects of those changes.
