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.
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.
Determining Slopes from Equations, Graphs, and Tables
Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.
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.
Properties: Mixtures
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.
Electromagnetic Spectrum
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.
Ionic and Covalent Bonding
Students will predict which elements will form covalent or ionic bonds. Includes the Kid2Kid video, Types of Bonding.
Atomic Theory: Dalton, Thomson and Rutherford
Given scenarios or summaries of historical events leading to modern-day atomic theory, students will identify the author and experimental design of each and the conclusion drawn from these experiments.
Covalent Bonding: Electron Dot Diagrams
Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).
Ideal Gas Behavior: Avogadro’s Law
Given descriptions, scenarios, or diagrams, students will use Avogadro’s constant to calculate the weight in grams of a single atom or molecule of a substance.
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.
Using Geometric Concepts and Properties to Solve Problems
Given pictorial representations, the student will use geometric concepts and properties to solve problems from art and architecture.
Using Proportional Relations to Find Missing Measurements of Two-Dimensional Figures
Given pictorial representations and problem situations of 2-dimensional figures or 3-dimensional figures, the student will use proportional reasoning to find a missing measurement.
Using Rational Numbers to Solve Problems
Given a problem situation in verbal form, students will select and use an operation involving rational numbers in order to solve the problem.
Selecting and Using Appropriate Forms of Rational Numbers
Given real-life problems, the student will select an appropriate method and solve problems involving proportional relationships.
