Start with 1km, then convert to your hops . . .

(Note: 1000 m = 1 km; 100 cm = 1 m; __________ cm = 1 average hop )

5

Measure, in seconds, how long it takes you to walk 10 meters. (10 "blocks in the Hall)

(Note: 10 m = _____ s)

6

1

Average your hops. (Note: __________ cm = 1 average hop)

7

1

How many hours would it take you to walk 68.8 miles.

(Note: 1000 m = 1 km; 1 miles = 1.609 kilometers; 60 second = 1 min; 60 min = 1 hour)

Find the mass, in grams, of your tootsie roll.

9

1

Record the time, in seconds, it takes to chew one tootsie roll until it is gone.

10

1

Record the grams chewed per second --> mass diveded by time ( ____ g/s)
