Students will distinguish between descriptive, comparative, and experimental investigations.

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

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.

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

This resource is intended to use for Tier I classroom instruction.

This resource can be used, in conjunction with best practices, for Tier I classroom instruction.

A resource to be used for Tier I instruction for the introduction of the structure of atoms.

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

This resource provides Tier I instruction ideas for Grade 6+ science teachers in the area of potential and kinetic energy.

Given schematic diagrams, illustrations or descriptions, students will identify the relationship of electric and magnetic fields in applications such as generators, motors, and transformers.

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

This resource provides alternative or additional tier-one learning options for students learning about heat transfer, Chemistry TEKS (11)(B).

This resource supports Chemistry TEKS (11)(A).
