Covalent Bonding: Electron Dot Diagrams

Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).
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.
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.
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)
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.
Cell Comparisons

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.
Conservation of Momentum

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