OCEAN ROBOTS: WHAT? HOW? WHY? * Lesson Plan PPT to use with students *

Opening Questions?  How deep may penguins go to find their food?  What could be going on in the ocean below the surface?

WHAT IS A ROBOT?

Why study ocean conditions from a glider? ProsCons

What happens?

What does your data from the glider tell you about how the ocean water may vary with depth and/or across space?

Student Observations

Salinity

Chlorophyll

Temperature

What could this mean?  Why is most of the chlorophyll at and near the surface?  If most of the chlorophyll is at and near the surface, where would you expect to see most of the krill? Why?  What does that mean for where we may find penguins eating?

How the Glider Collects Data

Daily Questions 1. What kinds of data do gliders collect?
