11 OnTRACK Grade 8 Math: Proportionality
Students learn to to use proportional relationships to describe dilation; explain proportional and non-proportional relationships involving slope; and use proportional and non-proportional relationships to develop foundational concepts of functions.
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.
Given illustrations or scenarios, the student will identify an enzyme and the outcome of its action.
Animal System Interactions
Given illustrations, descriptions, or scenarios, students will describe the interactions that occur among systems in humans.
Mechanisms of Genetics: Protein Synthesis
Given illustrations or partial DNA or mRNA sequences, students will identify the processes and purposes of transcription and translation.
Given scenarios, illustrations, or descriptions, the student will describe the flow of matter through carbon and nitrogen cycles and describe the consequences of disrupting these cycles.
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: System Organization
Given illustrations or descriptions, students will relate the levels of organization to each other and to the whole system.
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.
Given scenarios or illustrations, the student will determine the nature and type of relationship between organisms, including parasitism, commensalism, mutualism, and competition.
Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.
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.
Predict Monohybrid Crosses
Biology Kid2Kid videos present biology concepts taught to a student by a student. This resource contains videos that explain monohybrid crosses in both English and Spanish.
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.
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.
