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.
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.
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.
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.
Dichotomous Keys Murder Mystery

A resource for the instruction of (7)(11)(A) involving the use of dichotomous keys for identification.
Scientific Notation

Given quantitative data students will express and manipulate chemical quantities using scientific notation.
Significant Figures

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

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