This more of an "atta boy" than a question. 
Your video of the krill feeding on the ice was wonderful! It provided visuals to help reinforce the answers that my students last year looked for regarding that valuable part of the food chain. I am contacting those students and having them come by after school to view it with me and have a follow-up discussion. Thanks so much for the great materials. I wish we could participate in the event today, but we have a speaker in our classroom at the time of the "Live" event so we will view it from the archive later. I hope all goes well.
