Types of Science Investigations

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

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.
Push Back, Pull Forward
Students will conduct an experiment to demonstrate force such as pushes and pulls.
Demonstration and Analysis of Dihybrid Crosses
The students will review related vocabulary, watch the teacher model a dihybrid cross, and then perform a dihybrid cross and answer questions about the outcomes with a partner.
Cell Homeostasis: Osmosis

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.
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)
Newton's Three Laws of Motion

This resource provides alternate or additional learning opportunities for students learning the three Newton's Laws of Motion. It includes a collection of interactive materilas, videos, and other digital media. Physics TEKS, (4)(D)
Weathering and Decomposition

A Tier 1 earth science instructional resource for grade 3
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.
Introduction to Plate Tectonics

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

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

A resource to be used for Tier I instruction for the introduction of the structure of atoms.
Investigating and Comparing Life Cycles

A Tier I life science instructional resource for grade 3
Protein Synthesis

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

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