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.
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.
Given scenarios, illustrations. or descriptions, the student will compare variations and adaptations of organisms in different ecosystems.
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.
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.
Increasing and Decreasing Energy
This resource provides sample activities for teachers to use in helping students to identify and investigate the effects of increasing and decreasing amounts of light, heat, and sound energy on an object.
Weathering and Decomposition
A Tier 1 earth science instructional resource for grade 3
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.
Light: Reflection and Refraction
This is a tier I instructional resource to provide a scaffolded learning experience for TEKS (5)(6)(C).
Learners compare a variety of prokaryotes and eukaryotes to determine similarities and differences among and between them.
What's Happening with the Weather?
This resource shows how to observe and describe weather changes from day to day and over seasons.
Introduction to Plate Tectonics
This resource is intended to use for Tier I classroom instruction.
