Test tubers

Nov. 19, 2019 | Potatoes were bored this afternoon in IB Biology, but students certainly weren't!

Our Form VI students continued their study of cell biology today, this time in Mrs. Lévesque IB Biology HL class. Busying themselves in the lab, Lisa, Diana, and the other students applied their theoretical knowledge to estimate the osmolarity of potato cells. This involved cutting the potatoes into consistently sized cylinders using a boring device and placing the pieces into solutions with varying concentrations of sucrose. Students will then return to the samples tomorrow, weighing each cylinder again to determine whether the potatoes have lost or gained weight, allowing them to estimate the concentration of sucrose in the potatoes themselves. We can see why students find this class a-peel-ing!
