Mystery Stations Qualitative Students rotate around stations
Observe Explain Guess at what they all have in common
Newton’s 1st Law–Inertia
Carts & Masses Quantitative investigation Design and execute an experiment to
determine how the motion depends on applied force
Represent findings through a graph Newton’s 2nd Law Fnet = ma
Force Meters Introduce force due to gravity Create home-made force meter Fgrav = mg Fspring = -kx
Tug-of-War Quantitative Use force meters
to investigate action-reaction
Newton’s 3rd Law Fa,b = –Fb,a

“Draw the forces” Free-Body Diagrams
The Glider Engineering Challenge
Design and build a working glider Conduct an experiment to optimize the
design Design Report I
Analysis & FBDs Launch Competition Design Report II
Analysis of Launch & Reflection
The Glider Engineering Challenge
Build a working glider Must slide freely in track Must have notch at nose for string
attachment Conduct an experiment to optimize one
aspect of the design Launch Competition
m = 5.70 kg
