Purpose: Watch a 6-minute video comparing two of the coral reefs in Key West, White Banks Reef and Dino's Rock.

Instructions: Here is the website.

JOURNAL ASSIGNMENT:

Here is a short explanation of the movie:
We want to get to the bottom of things. Especially the ocean! We built an ROV, which stands for Remotely Operated Vehicle. We control it from above and it goes way down into the ocean. When we heard that some of the Florida Keys' coral was diseased, damaged and beginning to die, we wanted to learn more. What can our ROV tell us about the health of a coral reef?

After checking some maps at a marine lab, we chose two reefs to explore with our ROV. White Banks Reef gets a lot of human traffic and Dino's Rock is pretty deserted. We marked four different spots every five meters. We used the ROV to check out the reef's health at each marked spot. We recorded any disease or damage. We looked at the ROV's videotape and gave each spot a rating from 1-5 on how healthy it seemed. (One meant unhealthy, and five meant healthy.) Then, we recorded our data in a bar graph.

First, answer a few questions [it would be wise to read these questions before and after the video]:
