Optional Lessons

The third and fourth lessons are optional and involve student projects. Each project concentrates on one of the many adaptations of elephant seals: elephant seals migrate farther than any other mammal, have adapted to life at near-freezing temperatures, are able to dive as deep (if not deeper) than any other marine mammal, never require a drink of water, can go for months without eating, etc. These lessons were originally developed by the Point Reyes National Seashore Association (http://www.nps.gov/pore/forteachers/upload/curriculum_elephantseal.pdf).

Note
Optional days 3 and 4 involve a class project adhering to the lesson plans “Discovering Northern Elephant Seals: How Are Elephant Seals Adapted to Their Environment?”.  This class project examines elephant seal adaptations to a marine environment, including: fasting, concentrated urine, energy from fat, thermoregulation, chest shields, big noses/proboscis, delayed implantation, female choices in mating, vocalizations, and molting, black pup fur, sleep apnea/breath holding, and locomotion.

Objective
Students will create posters or skits based on specific adaptive characteristics of elephant seals. 

This exercise can be modified for high school classes or advanced middle school classes by allowing students to prepare PowerPoint presentations for the class. If this is the case, the lessons could be scheduled  to give students considerably more time to complete their projects.

Materials/Resources
Handouts (copied from the pdf materials below), poster paper, scissors, drawing supplies.

Procedure
  1. Lead a discussion of the types of adaptations students came up with in lesson one.  Do they think elephant seals actually have most of those adaptations? Elephant seals probably have even more amazing adaptations than the ones they came up with.
  2. There are a total of 15 Elephant Seal Adaptation Cards. Divide students into teams so that all of the adaptations are distributed. Each team receives an adaptation card, a note-taking guide and poster paper.
  3. Students research the adaptation and develop posters or skits based on their adaptation card.
