In this episode of the World’s Most Exciting Classroom, host Joe Grabowski broadcasts live from the DARWIN200 ship en route from Tenerife, Canary Islands to Cape Verde. He introduces a special Explorer’s Club flag on the tallship Oosterschelde and interviews camera operators Rhodri Hall and Tom Dixon about their filming experiences on board and in Tenerife. Darwin Leader Iro Tsarmpopoulou-Fokianou and cameraman Lorimer Macandrew share their encounters filming short-finned pilot whales in Tenerife’s waters, culminating in a screening of Iro’s completed Darwin Leader film on pilot whale conservation. The episode also features a Kahoot! quiz and reveals the winners of the previous ocean acidification experiment. This week’s activity explores island evolution using examples like Komodo dragons and Brookesia chameleons, prompting viewers to contemplate why these species evolved to their respective sizes.
