How Do We Quantify the Building Blocks of Matter?
This resource provides flexible alternate or additional learning opportunities for students learning about the mole concept, Chemistry TEKS (8)(A).
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.
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.
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.
Making Conjectures About Circles and Angles
Given examples of circles and the lines that intersect them, the student will use explorations and concrete models to formulate and test conjectures about the properties of and relationships among the resulting angles.
Solving Problems With Similar Figures
Given problem situations involving similar figures, the student will use ratios to solve the problems.
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.
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.
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.
Average Atomic Mass
Given descriptions, scenarios, or diagrams, students will calculate the average atomic mass by weighted average.
Periodic Table Trends
Given descriptions, scenarios, or groups/series of elements, students will use the Periodic Table to relate the size of the atomic radii, electronegativity, and ionization energy of elements to their position on the chart. Students will need to be familiar with the trends of the Periodic Table.
