Jumping in the air - What was your height?

-Access prior knowledge of students in solving equations

-Use digital cameras to film students jumping.
-Import film clips into computer(s)
-Use video-editing software (Moviemaker) to find the time students are in the air
-Students can use this data in the quadratic formulas h=-16t^2 +vt +s and h =-16t^2+s
-Discuss which formula would make more sense. How would the dropped formula work in this situtation?
-From this info, students can find the initial velocity they jumped.
-They can create graphs, tables, and equations.
-From the equation they will calculate their maximum height.
-Have students chart on posters and do a gallery walk. Have them comment on post-its any questions they may have about technqiues or solving.

extenstion - have students try different ways to try and get "better hang time".
