Floating and Sinking: Exploring Density in Everyday Objects

The video tutorial introduces a floating and sinking experiment. The teacher guides a student through testing various objects, such as a paper board, pebble, paint bottle, leaf, coin, flower, spoon, metal ball, chalk, plastic ball, ring, wooden spoon, shells, paper cup, pencil, sponge, eraser, and sharpener, to determine if they float or sink in water. The experiment demonstrates that objects lighter than water float, while heavier objects sink. The session concludes with encouragement to repeat the experiment at home.
