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

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

Learners calculate the probability of genotypic inheritance and phenotypic expression using mono- and dihybrid crosses.

Learners analyze and evaluate the effects of other evolutionary mechanisms.

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.

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

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

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

This resource provides flexible alternate or additional learning opportunities for students learning about the mole concept, Chemistry TEKS (8)(A).

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

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.

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.

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.

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

This resource utilizes videos, investigations, and interactives to help students understand and describe the role of internal feedback mechanisms.

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

Students will understand Bohr’s experimental design and conclusions that lead to the development of his model of the atom, as well as the limitations of his model.

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

Given illustrations or descriptions, students will predict the shape of molecules based upon the extent of the electron pair electrostatic repulsion.

Given scenarios or diagrams, students will describe the nature of metallic bonding and explain properties such as thermal and electrical conductivity, malleability, and ductility of metals.
