ACS Pathshala on Instagram: "That playground seesaw isn’t just fun — it’s science! It follows the rule of a First Class Lever, where the fulcrum is in the middle, effort on one side, and load on the other. Seesaws, scissors, and weighing balances, all work on the same principle. Next time you play or use them, remember — you’re living science, not just learning it!
