###
3.02 Average Speed and Average Velocity

In this video, we explore the difference between speed and velocity, and their relationship to distance and displacement.

###
3.03 Kinematic Equations in One Dimension

In this video, we introduce the three primary kinematics equations and apply them to one-dimensional problems. The term "acceleration" is also introduced.

###
3.04 Kinematic Equations Graphical Analysis

In this video, we analyze hypothetical experiments by graphing position, velocity, and acceleration versus time, qualitatively.

###
3.05 Kinematic Equations in Two Dimensions

In this video, we apply the three primary kinematic equations to projectile motion problems.

###
3.06 Relative Motion

In this video, the inherent (classical) relativity of velocity measurements is explored, qualitatively and quantitatively, in both one and two dimensions.

###
3.01 Distance and Displacement

In this video, we explore the difference between distance traveled (an example of a scalar) and displacement (an example of a vector), and we review some basic vector math.

###
Equipment for Biology

Given investigation scenarios, students will determine the equipment that best fits the procedure.

###
Disruptions of the Cell Cycle: Cancer

Given illustrations or descriptions, students will identify disruptions of the cell cycle that lead to diseases such as cancer.

###
Mechanisms of Genetics: DNA Changes

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

###
Solving Quadratic Equations Using Algebraic Methods

Given a quadratic equation, the student will solve the equation by factoring, completing the square, or by using the quadratic formula.

###
Quadratics: Connecting Roots, Zeros, and x-Intercepts

Given a quadratic equation, the student will make connections among the solutions (roots) of the quadratic equation, the zeros of their related functions, and the horizontal intercepts (*x*-intercepts) of the graph of the function.

###
Using the Laws of Exponents to Solve Problems

Given problem situations involving exponents, the student will use the laws of exponents to solve the problems.

###
Formulating Systems of Equations (Verbal → Symbolic)

Given verbal descriptions of situations involving systems of linear equations the student will analyze the situations and formulate systems of equations in two unknowns to solve problems.

###
Solving Quadratic Equations Using Graphs

Given a quadratic equation, the student will use graphical methods to solve the equation.

###
Determining the Meaning of Intercepts

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the intercepts of the function and interpret the meaning of intercepts within the context of the situation.

###
Predicting the Effects of Changing y-Intercepts in Problem Situations

Given verbal, symbolic, numerical, or graphical representations of problem situations, the student will interpret and predict the effects of changing the *y*-intercept in the context of the situations.

###
Solving Linear Inequalities

The student will represent linear inequalities using equations, tables, and graphs. The student will solve linear inequalities using graphs or properties of equality, and determine whether or not a given point is a solution to a linear inequality.
