Inside a bright afternoon classroom, Ma'am Nika stands beside a chalkboard showing "KE=1/2mv^2, PE=mgh, ME=KE+PE". Ruru and Migo sit at front desks, eyes wide, notebooks open.
Ma'am Nika told Grade 8, "Energy is everywhere at school." "KE is energy of motion: KE=1/2mv^2; PE is from height: PE=mgh." "Mechanical energy adds both: ME=KE+PE."
On the sunny outdoor school basketball court, Ruru hangs mid-air shooting toward the hoop, determined face, while Migo watches arms raised after passing the ball. Ma'am Nika stands by the sideline, smiling and pointing upward.
At the court, Migo passed to Ruru. "Dribbling is KE," said Ma'am Nika. Ruru jumped to shoot. "Higher means more PE," Ma'am Nika added. The ball falls, speeding; "KE rises, ME=KE+PE," Migo cheered.
Under bright hallway fluorescents, Migo leans forward transitioning from a run to a controlled brisk walk, brows raised. Ma'am Nika beside a locker lifts an instructive finger, while Ruru stands nearby holding textbooks, smiling knowingly.
After class, Migo rushed down the hallway. "Walk, please; KE rises with speed," Ma'am Nika warned. Migo slowed to a brisk walk. "Double speed, about four times KE, v^2," Ruru said.
Inside the well-lit science classroom, Ruru and Migo strain together pushing a metal book cart stacked with physics texts toward a lab table. Ma'am Nika watches from the blackboard, arms crossed and approving smile.
In science class, Ruru and Migo pushed a book cart. "That motion is KE," Ma'am Nika said. They lifted a box; "higher gives PE," she added. "ME totals both: ME=KE+PE," the class echoed.
