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.

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.

Given quantitative data, students will express and manipulate quantities using dimensional analysis.

Given examples, descriptions, and illustrations, students will be able to describe the role of DNA, RNA, and environmental factors in cell differentiation.

Given quantitative data, students will express and manipulate quantities using the correct number of significant figures.

Given information extracted from current events, news reports, journal articles, marketing, or promotional materials, students will evaluate the claims for validity.

Given illustrations or descriptions, students will predict the shape of molecules based upon the extent of the electron pair electrostatic repulsion.

Given scenarios or diagrams, students will describe the nature of metallic bonding and explain properties such as thermal and electrical conductivity, malleability, and ductility of metals.

Given descriptors, diagrams, and chemical symbols, students will use the periodic table to determine the electron configuration of neutral atoms.

Given descriptions or chemical formula of a substance, students will use the concept of a mole to relate atomic mass to molar mass.

Given diagrams, scenarios, or illustrations, students will identify the characteristics of the Doppler effect.
