###
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.

###
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.

###
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.

###
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.

###
Cell Specialization and Differentiation

Given examples, descriptions, and illustrations, students will be able to describe the role of DNA, RNA, and environmental factors in cell differentiation.

###
Survival of a Species

Given scenarios, illustrations or descriptions, the student will describe how long-term survival of species is dependent on changing resource bases that are limited.

###
Conservation of Momentum

This resource was created to support TEKS IPC(4)(E).

###
Equipment for Biology

Given investigation scenarios, students will determine the equipment that best fits the procedure.

###
Cell Processes: Fermentation

Given descriptions or illustrations, students will identify where fermentation occurs and the results of fermentation.

###
Disruptions of the Cell Cycle: Cancer

Given illustrations or descriptions, students will identify disruptions of the cell cycle that lead to diseases such as cancer.

###
Mechanisms of Genetics: DNA Changes

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.
