“I can’t find it!” your teacher exclaims from her desk. “I don’t know where I put the password for our video conferencing call today.” Your class was selected to participate in a Skype call with science researchers at McMurdo Station in Antarctica to learn about this unique ecosystem. “Didn’t you receive a packet with information last week?” you ask as you recall her excitement when a large manilla envelope postmarked with a penguin had arrived. “Yes, I went through all of the materials when they first arrived, and saw the page with the directions for our call, but it’s not with those things now,” she says as she spreads the materials out on the desk. “Students I need your help to find the missing password or we are going to miss out on our ice cap chat.”
