Students practiced determining distance and displacement, along with average speed, while tracking actual sharks on the West Coast.  Several sharks are fitted with a GPS device and every time they "fin" (come up to the surface), their locations are documented on a map.  Without technology, this activity would not be possible.  Here is a copy of the task, including the live website with shark locations.

The next activity is all about a shark. This is an actual shark that is tracked by marine biologists. Please go to the following website and follow the instructions. All answers will go in your notebook. Date today's entry and label it: MACK

http://www.fishtrack.com/live-track/
On this website, find Mack the Shark.
Locate his position on August 22 at approximately 2:57am. What was his displacement from the day the previous measurement was taken until August 22? E-mail me the answer.

Record data/analysis in notebook:
Later in the day Mack was found again. This time, at 4:39:48. What distance did it travel? What was its average speed?

Graph each leg (each spot) of Mack's Journey on the erasable graph. By simply looking at your distance/time graph, determine which leg was traveled at the fastest pace. How do you know?

What was the average speed of the journey from start to finish- in days? hours?
Why do you think he traveled so far compared to Sugarlips?
Using the reading selection below, determine what do they mean by "finning" and why is that when they take the coordinates of the shark?
