Unit Summary: Students will create a device to learn important aspects of motion and freefall. Students will also learn the kinematics concepts involved in projectile motion. Students will use statistics to make discoveries about data from the projects above.
Big Ideas:
Engineers use statistics to make informed decisions based upon established principles.
Visual representations of data analyses allow for easy distribution and understanding of data.
Statistics is based upon both theoretical and experimental data analysis.
Speed, velocity, acceleration, direction, angle of projection are all kinematic concepts used to describe bodies in motion.
Essential Questions:
Why is it crucial for designers and engineers to utilize statistics throughout the design process?
Why is process control a necessary statistical process for ensuring product success?
Why is theory-based data interpretation valuable in decision making?
Why is experiment-based data interpretation valuable in decision making?
What are the relationships between distance, displacement, speed, velocity, and acceleration?
Why is it important to understand and be able to control the motion of a projectile?
