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.
Newton's Law of Inertia
This resource provides instructional resources for Newton's First Law, the law of inertia.
Newton's Law of Action-Reaction
This resource is to support TEKS (8)(6)(C), specifically the Newton's third law or the law of action-reaction.
Equipment for Biology
Given investigation scenarios, students will determine the equipment that best fits the procedure.
Homeostasis—Succession
Given scenarios, illustrations, or descriptions, the student will identify the process of ecological succession and the impact that succession has on populations and species diversity.
Solving Problems With Similar Figures
Given problem situations involving similar figures, the student will use ratios to solve the problems.
