# Science Reasoning Center - 1-D Kinematics

Here is our current listing of Science Reasoning activities for 1D-Kinematics. All activities can be used as a Guest without Task Tracker or as a logged-in student with Task Tracker. Learn more about Task Tracker for Science Reasoning activities.

#### Kinematics

This activity includes a description of a ball tossed upward into the air. The description includes a dot diagram, a position-time graph, and a velocity-time graph. Questions target a student's ability to extract meaningful data from diagrams and graphs, to interpret graphs, and to make connections between the diagrams and graphs.

#### Velocity-Time Graph

This activity describes four different experiments involving the use of a motion detector and the resulting velocity-time graphs. Ten different types of motion (fast, slow, movement towards and away from the detector, constant speed, changing speed, etc.) are contrasted in the experiments. Questions target a student's ability to interpret data, to compare and contrast the results of the various experiments, to use the results of the experiments to evaluate the validity of a conclusion, to identify the supporting evidence for a conclusion, and to reason towards appropriate conclusions when given the findings of an experiment.

#### Moving Cart on an Inclined Plane

This activity presents data for a cart moving up and down and inclined plane in the form of position-time and velocity-time graphs. Students miust extract position or velocity data from a graph if given a time, extract a time value if given a position or a velocity value, determine a velocity value for given a position (and vice versa), and use information from the graph to support a variety of claims.

#### Stopping Distance

This activity presents data regarding the relationship between reaction time, car speed, reaction distance, braking distance, and total stopping distance. The data is presented in the form of a bar chart and a data table. Questions target a student's ability to recognize and use numerical patterns, to select relevant data from a graph or table, to combine information from two or more data presentations to answer questions, and to interpolate and extrapolate using the provided data.
