Projectile Motion
This resource provides alternative or additional tier-one learning options for students learning about projectile motion—Physics TEKS (4)(C).
Kinetic Molecular Theory
This resources allows students to explore the postulates of the Kinetic Molecular Theory in order to better understand why gas particles behave the way that they do.
Defining Similarity
Given similar figures, the student will use critical attributes to define similarity.
Generalizing Proportions from Similar Figures
Given a pair of similar figures, including dilations, students will be able to generalize that the lengths of corresponding sides are proportional.
Graphing Proportional Relationships
Given a proportional relationship, students will be able to graph a set of data from the relationship and interpret the unit rate as the slope of the line.
Analyzing Scatterplots
Given a set of data, the student will be able to generate a scatterplot, determine whether the data are linear or non-linear, describe an association between the two variables, and use a trend line to make predictions for data with a linear association.
Writing Geometric Relationships
Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
Exploring Probability with Independent Events
Given a problem situation, students will use experimental data or theoretical probability to make predictions and determine solutions to situations involving independent events.
Making Inferences and Convincing Arguments about Samples and Populations
Given problem situations that include given or collected data, the student will analyze the data and make inferences and convincing arguments based on the data.
Selecting and Using Appropriate Operations to Solve Problems
Given problem situations involving rational numbers, the student will select and use appropriate methods to solve the problems.
