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.
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.
The Bohr Model
Students will understand Bohr’s experimental design and conclusions that lead to the development of his model of the atom, as well as the limitations of his model.
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.
Given descriptors, diagrams, and chemical symbols, students will use the periodic table to determine the electron configuration of neutral atoms.
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.
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.
Using Multiplication by a Constant Factor
Given problems involving proportional relationships, the student will use multiplication by a constant factor to solve the problems.
Predicting, Finding, and Justifying Data from a Table
Given data in table form, the student will use the data table to interpret solutions to problems.
Conservation of Mass—It's the Law!
This resource includes videos, interactives, and additional resources to help students understand the law of conservation of mass and how to balance chemical equations.
Properties: Extensive and Intensive
Given descriptions or illustrations of properties, students will determine whether the property is chemical or physical, and if it is physical, if it is intensive or extensive.
Periodic Table Families
Given descriptions or specific element groups, students will use a Periodic Table to relate properties of chemical families to position on the table.
Solids, Liquids, and Gases
Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.
Given descriptions, scenarios, or illustrations of properties, students will distinguish between pure substances and mixtures.
Atomic Theory: Electromagnetic Spectrum
Given a diagram of the electromagnetic spectrum, students will relate the frequency to type of wave produced.
Given descriptions or illustrations, students will use the light and energy formula to solve for frequency, wavelength, or energy.
