Science 20F Exploring Distance, Speed & Time
Problem: What are the mathematical relationships between speed and time, distance and time, distance and
speed?
Prelab Questions: What are the general relationships between each pair of variables?
Materials: calibrated hot wheels track, car, metre stick, stop watch, box
Procedure (mini version): Set up the hot wheels track using the microscope box as a stand.
Part A: Distance and Time - Determine the time it takes the car to travel distances in Table 1 below. Use
the same speed each time. Start the timer at the start line.
Part B: Speed and Distance - Determine the distance the car travels in one second for each of the speeds in
Table 2 below.
Part C: Speed and Time - Determine the time it takes the car to travel 1 m for each of the speeds in Table 3
below. (make sure your car can tracel Im at vi

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
