In this episode of the World’s Most Exciting Classroom we’re sailing for Punta Arenas, Chile. We’re going to have a live uplink from the Oosterschelde with Nico and Daniel, two camera operators who spent their time bouncing around the rugged islands of the Falklands, filming the incredible wildlife. They’ll share stories from their time as well as photos and videos. We’ll have a Q&A session with them and the classrooms joining us. Find out the winners of the Testing PH with Cabbage experiment launched two weeks ago by our expedition leader, Stewart McPherson. Did your entry win one of three £50 prizes? See this week’s new experiment and undertake the challenge. Join a Kahoot quiz and live Q&A session!

Can you guess what this week’s Curiosity of the Week is?…and much more!
