#### Description:

This activity explores simple, straight-line motion by blending a motion sensor lab with student-generated digital graphs of distance versus time. First, learners use the online graph sketching tool to predict the motion of a person walking forward and backward over a 4-meter track in 30 seconds. Next, they try to reproduce their prediction graphs using a motion sensor to collect data. Finally, they analyze differences in slope between their original predictions and the actual data from the motion sensor.

#### CCSS.ELA-Literacy.RST.6-8.3: Common Core State Standards for English Language Arts & Literacy in History/Social Studies, Science,

Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.

#### CCSS.ELA-Literacy.RST.6-8.7: Common Core State Standards for English Language Arts & Literacy in History/Social Studies, Science,

Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually (e.g., in a flowchart, diagram, model, graph, or table).

#### CCSS.Math.Practice.MP2: Common Core State Standards for Mathematics

Reason abstractly and quantitatively.

#### CCSS.Math.Content.5.G.A: Common Core State Standards for Mathematics

Graph points on the coordinate plane to solve real-world and mathematical problems.

#### CCSS.Math.Content.5.G.A.2: Common Core State Standards for Mathematics

Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.

#### CCSS.Math.Content.6.EE.C: Common Core State Standards for Mathematics

Represent and analyze quantitative relationships between dependent and independent variables.

#### CCSS.Math.Content.6.EE.C.9: Common Core State Standards for Mathematics

Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

#### CCSS.Math.Content.8.EE.B: Common Core State Standards for Mathematics

Understand the connections between proportional relationships, lines, and linear equations.

#### CCSS.Math.Content.8.EE.B.5: Common Core State Standards for Mathematics

Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.

#### CCSS.Math.Content.8.F.B: Common Core State Standards for Mathematics

Use functions to model relationships between quantities.

#### CCSS.Math.Content.8.F.B.4: Common Core State Standards for Mathematics

Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

#### CCSS.Math.Content.8.F.B.5: Common Core State Standards for Mathematics

Describe qualitatively the functional relationship between two quantities by analyzing a graph (e.g., where the function is increasing or decreasing, linear or nonlinear). Sketch a graph that exhibits the qualitative features of a function that has been described verbally.
