In this unit, your students will construct, analyze, and/or interpret graphical displays of data to describe the relationships between types of energy (i.e., metabolic, potential, and kinetic) and an object's acceleration.
Developing models to illustrate the amount of energy stored in a system, they'll practice finding mathematical relations, and play with statistics and probability to find answers to a scientific question. In doing so, your students must consider the limitations of data analysis (e.g., measurement error) and/or seek to improve the precision and accuracy of data using better technological tools and methods (e.g., multiple trials).
Stretch with Data
Match graph values and explore margins of error qualitatively.
This Is Uphill
Graph energy consumption to gain potential energy.
Time for Squat Jumps
Graph potential energy at the maximum height of a jump.
Watch Your Steps
Explore kinetic energy during a movement at constant speed.
Aim for It
Explore kinetic energy during a movement using variable speed.
