Mendelian Genetics Using Monohybrids
Students will work collaboratively through a fictitious, real-world scenario to determine the probability of each breeding pair of dogs producing offspring with the desired trait for a fictitious client.
Proving an Ecosystem’s Health Through Succession
Students engage in viewing day three of ecosystem changes in lab groups to determine if the ecosystem is healthy or unhealthy based on scientific data and factors.
Gravitational Force

This resource provides flexible alternate or additional learning activities for students learning about the gravitational attraction between objects of different masses at different distances. IPC TEKS (4)(F)
Producing Plump Produce
In collaborative groups, the students investigate the transport of water within potato cells placed in various tonicity solutions.
Energy Transfer in an Ecosystem
All matter contains energy. Energy can be transferred from one object to another. Energy transformation can occur through the conversion of energy from one form to another. Energy is never created nor destroyed; it is always transferred and/or transformed. Students will demonstrate how energy is transformed and transferred in an ecosystem. To do this, students will create energy pyramids by stacking cups that represent organisms and available amounts of energy. Students will graph and analyze the data.
Plant, Parts, and Function
Students use prior knowledge of body systems as they make connections to systems in plants. Students learn that some plant systems have similar functions as the respective animal systems. The lesson highlights the following systems in plants: root system, shoot system, vascular system, and reproductive system.
Equipment for Biology

Given investigation scenarios, students will determine the equipment that best fits the procedure.
Disruptions of the Cell Cycle: Cancer

Given illustrations or descriptions, students will identify disruptions of the cell cycle that lead to diseases such as cancer.
Mechanisms of Genetics: DNA Changes

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.
Conservation of Momentum

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

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

Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.
Biological Systems: Homeostasis

Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.
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.
Organisms' Adaptations

Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.
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)
Cell Comparisons

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