Identify major scientific, mathematical, and medical achievements of the Islamic Golden Age and explain how they preserved and expanded on earlier knowledge.
Starting in the 700s CE, the Abbasid Caliphate built a new capital at Baghdad and made it one of the greatest centers of learning on Earth. Caliphs -- especially al-Ma'mun, who ruled 813-833 CE -- funded a great research library and translation center called the House of Wisdom (Bayt al-Hikma). Scholars there translated Greek, Persian, and Indian texts into Arabic, saving many works that might otherwise have been lost forever, and then pushed the ideas further with their own discoveries. This was not just copying old knowledge -- it was centuries of original science, math, and medicine happening in Baghdad, Cairo, and Cordoba while much of Europe had far fewer large libraries.
One scholar, Muhammad ibn Musa al-Khwarizmi, worked at the House of Wisdom around 820 CE and wrote a book on solving equations. Its Arabic title included the phrase "al-jabr," which became our word algebra, and his own Latinized name gave us the word algorithm. In medicine, Ibn Sina (known in Europe as Avicenna) wrote The Canon of Medicine around 1025 CE, a massive encyclopedia that European universities used as a textbook for over 500 years. Other scholars refined the astrolabe (a tool for measuring the position of stars, useful for navigation and for timing daily prayers) and helped spread paper-making, a technology that had reached the Islamic world from China and would later travel on into Europe -- the same trade routes you will study next week.
Mastery looks like: They can name at least two Islamic Golden Age scholars and their fields, and explain that this era both preserved earlier knowledge and produced original discoveries.
Common stumbles: Treating the Islamic Golden Age as mere "preservation" of Greek ideas rather than recognizing the original math, medicine, and science produced there.
