Valence Shell Electron Pair Repulsion
Given illustrations or descriptions, students will predict the shape of molecules based upon the extent of the electron pair electrostatic repulsion.
Chemical Bonding: Metallic Bonds
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.
Nomenclature: Covalent Compounds
Given descriptions, diagrams, or scenarios, students will write and name the chemical formulas of binary covalent compounds.
Ionic Bonds: Electron Dot Formulas
Given descriptions, diagrams, scenarios, or chemical symbols, students will model ionic bonds using electron dot formulas.
Moles and Molar Mass
Given descriptions or chemical formula of a substance, students will use the concept of a mole to relate atomic mass to molar mass.
Types of Solutions: Saturated, Supersaturated, or Unsaturated
Given scenarios, graphs, diagrams, or illustrations, the student will determine the type of solution such as saturated, supersaturated, or unsaturated.
Finding the Probabilities of Dependent and Independent Events
Given problem situations, the student will find the probability of the dependent and independent events.
Recognizing Misuses of Graphical or Numerical Information
Given a problem situation, the student will analyze data presented in graphical or tabular form by evaluating the predictions and conclusions based on the information given.
Evaluating Methods of Sampling from a Set of Data
Given a problem situation, the student will evaluate a method of sampling to determine the validity of an inference made from the set of data.
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.
Using Logical Reasoning to Prove Conjectures about Circles
Given conjectures about circles, the student will use deductive reasoning and counterexamples to prove or disprove the conjectures.
Creating Nets for Three-Dimensional Figures
Given nets for three-dimensional figures, the student will apply the formulas for the total and lateral surface area of three-dimensional figures to solve problems using appropriate units of measure.
Drawing Conclusions about Three-Dimensional Figures from Nets
Given a net for a three-dimensional figure, the student will make conjectures and draw conclusions about the three-dimensional figure formed by the given net.
Generalizing Geometric Properties of Ratios in Similar Figures
Students will investigate patterns to make conjectures about geometric relationships and apply the definition of similarity, in terms of a dilation, to identify similar figures and their proportional sides and congruent corresponding angles.
Determining Area: Sectors of Circles
Students will use proportional reasoning to develop formulas to determine the area of sectors of circles. Students will then solve problems involving the area of sectors of circles.
Converting Between Measurement Systems
Given a real-world situation with measurements in either metric/SI or customary units, the student will solve a problem requiring them to convert from one system to the other.
