Have you ever wondered how to find the density of an oddly shaped object like a stone or a small metal piece? Unlike a perfect cube or cylinder, we can’t simply measure the sides and calculate its volume.
Using water displacement, the students of grade 8 successfully determined the volume and density of an irregular object. This experiment illustrates Archimedes’ principle in action and reinforces the concept that density is the mass per unit volume, regardless of an object’s shape. This method is very useful for finding the density of small, irregular-shaped solids like stones, gems, or metals — important in industries such as construction, jewellery-making, and materials science.
