Intersection of Lines
Determine the coordinates where two different lines intersect to solve word problems involving linear relations.
Parallel and Perpendicular Lines
Discover how the slope of a line compares between lines are parallel or perpendicular to one another.
Linear Relations
This question set explores the graphs and equations of lines in slope-intercept form. By the end of the question set, students should be able to calculate the slope and y-intercept of a line given its graph or equation.
Parabolas
This question set shows how quadratic functions can be graphed using the vertex and zeroes.
Quadratic Formula
Apply the quadratic formula to solve quadratic equations. The role of the discriminant will be explored to determine the number of roots in a quadratic equation.
Odds
The definition of odds and its connection to probability will be explained. The concept of odds will then be applied to real-life scenarios, such as winning the lottery.
Conditional Probability
This question set explores the probability that a certain will occur, given that another related event has occurred.
Probability Events
An introductory question set to probability. The concept of events, sets of outcomes, and sample spaces will be explored.
Exothermic and Endothermic Reactions
This is a long sequence of questions that develops the concept of exothermic and endothermic reactions. It begins with basic definitions and applying those concepts to synthesis and decomposition reactions. The concept of Energy-time graphs is discussed in detail which then leads into questions about enthalpy and the change in energy of a reaction system. The sequence ends with 2 industrial applications about reducing CO2 emissions and producing hydrogen for hydrogen cars.
Predicting Products
Includes questions and descriptions about how to predict what type of reaction is occurring and the best practices for predicting what the products or reactants will be given part of a chemical equation. The set ends with some challenge questions that involve stoichiometry and combining two reactions into one equation.
Stoichiometry
A series of questions that leads students step by step through the process of solving stoichiometry questions. Contains a focus on the best practices for writing out stoichiometry calculations.
The Mole
The concept of what the mole is and how the units of atomic mass unit (amu) and grams are related through the Avogadro number are explored. Classification of matter is also discussed regarding the distinction between atoms and molecules.
Mole Ratios
The concept of mole ratios between the atoms in a molecule and the mole ratios between different compounds in a chemical reaction (and thus balanced chemical equations) are explored. This concept then leads into stoichiometry calculations.
Conversion Factors
Different types of mole calculations are explored using the conversion factors of molar mass, concentration, and volume of a gas. An emphasis is placed on correctly setting up the calculations so that units cancel out.
Reference Angles
The concept of reference angles will be used to find equivalent ratios for sine, cosine, and tangent in different quadrants.
