Product and Quotient Properties of Exponents
This lesson helps students understand two foundational exponential properties: The Product and Quotient Properties of Exponents. Students will collaborate to formulate a rule for these properties. Ultimately, students should conclude that when the same bases are being multiplied, exponents will be added; and when the same bases are being divided, exponents will be subtracted. As the lesson progresses, students will apply these rules to simplify expressions of various difficulties.
Using Linear Equations to Count Pecans
Students will write linear equations in point-slope form given two points via a verbal description.
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.
Given illustrations, diagrams, or descriptions, students will identify alpha, beta, or gamma radiation.
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.
Nuclear Chemistry: Radioactive Decay
Given illustrations, symbols, or descriptions, students will balance nuclear equations.
Fusion and Fission
Given diagrams, illustrations, symbols, or descriptions, student will distinguish between nuclear fusion and nuclear fission.
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.
Ideal Gas Behavior: Dalton's Law
Given descriptions, scenarios, or diagrams, students will use the Dalton’s Law of partial pressure to calculate the pressure of an individual gas or that of a mixture of gases.
Forms of Energy
Given diagrams, illustrations, or descriptions, students will identify the types of energy.
Law of Conservation of Energy: Heat Transfer
Given illustrations, scenarios, descriptions, and/or diagrams, students will demonstrate understanding of heat transfer.
