Answer:
Harappans were among the first to develop a system of uniform weights and measures that conformed to a successive scale. The smallest division, approximately 1.6 mm, was marked on an ivory scale found in Lothal, a prominent Indus Valley city in the modern Indian state of Gujarat. It stands as the smallest division ever recorded on a Bronze Age scale. Another indication of an advanced measurement system is the fact that the bricks used to build Indus cities were uniform in size.
Harappans demonstrated advanced architecture with dockyards, granaries, warehouses, brick platforms, and protective walls. The ancient Indus systems of sewerage and drainage developed and used in cities throughout the region were far more advanced than any found in contemporary urban sites in the Middle East, and even more efficient than those in many areas of Pakistan and India today.
Harappans were thought to have been proficient in seal carving, the cutting of patterns into the bottom face of a seal, and used distinctive seals for the identification of property and to stamp clay on trade goods. Seals have been one of the most commonly discovered artifacts in Indus Valley cities, decorated with animal figures, such as elephants, tigers, and water buffalos.
Harappans also developed new techniques in metallurgy—the science of working with copper, bronze, lead, and tin—and performed intricate handicraft using products made of the semi-precious gemstone, Carnelian.
