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.
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.
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.
Data Organization
Given field and laboratory scenarios and laboratory data, students will construct data tables and graphs, using repeated trials and means to organize data.
Conclusions and Scientific Explanations
Given laboratory investigation data, students will determine the best conclusion based upon that data.
Measurement
Given investigation quantitative data, students will determine its degree of precision and/or accuracy and causes for uncertainties in measured data.
Newton's Law of Inertia
This resource provides instructional resources for Newton's First Law, the law of inertia.
Conservation of Momentum
This resource was created to support TEKS IPC(4)(E).
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.
Living Organisms
A Tier 1 life science instructional resource for grade 2
Equipment for Biology
Given investigation scenarios, students will determine the equipment that best fits the procedure.
