What happens

Mrs. Krabappel, Bart's teacher, with a tall brown hairdo and green cardigan, stands beside a blackboard reading PHOTOSYNTHESIS, tapping a piece of chalk against her chin and smiling, then crosses her arms and underlines the word in white chalk. In the classroom, a student with blue hair and glasses sits at a wooden desk in the middle row while a large yellow hand in the foreground holds up a piece of chalk, and a curly-haired girl with glasses sits to the left. Bart, the boy with spiky hair in an orange shirt, sits at a desk with wide, uneasy eyes, with a blue-haired kid with green-tinted glasses and a spiky-haired kid with round eyes beside him, and a wall notice and a corkboard visible behind.
