This is a re-broadcast lesson with live questions answered via chat

FREE - Diving off the wall

Due to the ongoing outbreak of Coronavirus disease (COVID-19), the Wave Actions and Reactions lesson has been replaced with this rebroadcast, and as such questions cannot be answered during the lesson.
An expert educator live in the Cayman Islands will be on hand to answer any questions you have during this fantastic lesson using the Youtube Live Chat function.

This broadcast will be along the edge of the vertical wall which goes from 20ft to 2000ft. The underwater educator will communicate constantly with the lesson host (who will be on the boat). The educator will take the students through a series of fun facts and learning objectives regarding the geologic and oceanographic history of the “wall” and Little Cayman.

Students will have an in-class activity to complete during the lesson. The dive will observe changes in ecosystems at various depths including: small niches, large expanses of vertical wall, and blue water communities along the wall. Pre-recorded footage and images will be used to show changes in geology and oceanography over time, as we are only able to show a snapshot of what reefs look like today during the broadcast.

Preparation

Prepare for this live lesson by reviewing the attached learning resources.

Please note, that due to the circumstances outlined, any pre-submitted questions will now be answered via the Live Chat function, where you can also ask any further questions during the broadcast.

Learning Objectives
  • Define plate tectonics and the Mid-Ocean Ridge.
  • Describe the change in life and underwater communities along the Cayman Trough at various depths.
  • Explain why an animal may live on the wall instead of in a shallow reef.
  • Analyse the changes in the wall throughout the dive: number of sponges, amount of algae, colour of the corals, size of the fish, etc.
  • Discuss how the famous “wall” of the Cayman Islands was formed.
Live lesson outline

1. Introduction (5 mins)

The CCMI host welcomes students and outlines the lesson, introducing the educator and the in-class activity

2. The Cayman trench and the 'wall' (5 mins)

The educator will take the students through a series of fun facts and learning objectives regarding the geologic and oceanographic history of the “wall” and Little Cayman.

3. A guided tour (5 mins)

The underwater educator will take students on a tour of the wall at various depths.

4. Questions (5 mins)

At this point, the educator will answer common questions about the diving, the Cayman trench and coral in general. This is a good time to also submit any questions to the live chat, where a coral educator in the Cayman islands is waiting to answer you.

5. The bottom of the sea (5 mins)

Educator explains change in the oceans benthic habitat based upon basic geologic and oceanographic theory.

6. Questions (10 mins)

The educator then engages students to report their observations from the different environments along the wall.

7. Questions (5 mins)

At this point, the educator will answer more common questions about the diving, the Cayman trench and coral in general. This is a good time to also submit any questions to the live chat, where a coral educator in the Cayman islands is waiting to answer you.

8. Final questions and recap (5 mins)

The CCMI host recaps the learning objectives and concludes the lesson.
