Given choices of natural resources and lab materials, students will select disposal and recycling methods that best conserve and protect our resources

Given investigation scenarios, students will determine the equipment that best fits the procedure.

Given illustrations or descriptions, students will identify disruptions of the cell cycle that lead to diseases such as cancer.

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

Given examples, students will recognize the importance of taxonomy to the scientific community.

Given illustrations or descriptions, students will determine the classification of organisms into domains and kingdoms.

Given images, videos, or scenarios, identify and describe the responses of organisms, populations, and communities to various changes in their external environment.

Identify and describe internal feedback mechanisms involved in maintaining homeostasis given scenarios, illustrations, or descriptions.

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.

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.

Given laboratory investigation scenarios, students will determine the question or purpose of the procedure.

Given a series of statements, students will determine if statements are testable hypotheses and determine the hypothesis that best fits a given procedure.

Given field and laboratory scenarios and laboratory data, students will construct data tables and graphs, using repeated trials and means to organize data.

Given laboratory investigation data in the form of tables, charts, and graphs, students will analyze and predict trends from the data.

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 a description or illustration of various models, students will describe how these models represent the natural world and evaluate the advantages and limitations of the models.

A Tier I life science instructional resource for grade 3 

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.
