Types of Science Investigations
Students will distinguish between descriptive, comparative, and experimental investigations.
Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.
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.
Given investigation quantitative data, students will determine its degree of precision and/or accuracy and causes for uncertainties in measured data.
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.
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.
Matter and Energy—Chemical Reactions
Given descriptions or illustrations, students will investigate how evidence of chemical reactions indicates that new substances with different properties are formed.
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)
Weathering and Decomposition
A Tier 1 earth science instructional resource for grade 3
A Tier 1 earth science instructional resource for grade 1.
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.
Food Chains, Food Webs, and Energy Pyramids
This resource provides flexible alternate or additional learning opportunities for students to diagram the flow of energy through living systems, Seventh Grade Science TEKS (7)(5)(C).
The Arrangement of Elements: The Periodic Table
This resource provides flexible alternate or additional learning opportunities for students to interpret the arrangement of elements on the Periodic Table, Eighth Grade Science TEKS (8)(5)(C).
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.
