Students will distinguish between and/or interpret the types of motion.

Using interactive exercises, students will describe the structure of atoms and the locations of particles with in the atom.

Using interactives, students will demonstrate that gravity is the force that governs the motion of our solar system.

Students will identify how light years are used to measure distances and sizes of components of the universe.

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.

Students will identify how global patterns of atmospheric movement influence local weather.

Students will describe producer/consumer, predator/prey, and parasite/host relationships as they occur in food webs.

Students will identify how humans depend on ocean systems and explain how human activities such as runoff, artificial reefs, or use of resources have modified these systems.

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.

This resource shows how to observe and describe weather changes from day to day and over seasons.

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.

A Tier I life science instructional resource for grade 3 

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 provides sample activities for teachers to use in helping students to identify and investigate the effects of increasing and decreasing amounts of light, heat, and sound energy on an object.

A Tier 1 earth science instructional resource for grade 3

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.
