Greg and Bella return for 2022 with a special lesson from primary school teacher Miss Osueke all about the heart.
Award-winning Miss Osueke will take us on a guided tour of the cardiovascular system, and challenge Greg and Bella to come up with new ways of remembering parts of the heart.
Join Greg and Bella in the task to find your resting heart rate and the 'in-lesson' exercise to increase it. Learn about the surprisingly valuable contents of our blood, including a precious metal which can be found in your mobile phone!
We'll also find out about the ways in which emotional heartbreak can have real medical implications, as Greg and Bella share their stories of young heartbreak.
Hear about the work of early heart surgery pioneer, Daniel Hale Williams, plus Miss Osueke's shock lupus diagnosis and the open heart surgery that saved her life.
Bad students of all ages are welcome. Expect brilliant teachers, captivating subjects but absolutely no homework.
