My favorite person I learned about this week is Al-Razi. He was born in 854 AD and died in 925 AD. He moved to Baghdad to receive a higher education and became a doctor. He worked in the hospital and was the first person to discover smallpox was a different disease than measles. Smallpox is a disease that makes blisters all over your body. He attracted a circle of students. He was kind and helped poor people. He wrote a book of medical instructions for the public. He collected the medical knowledge of many different cultures and put it into a single collection. His books were translated into Latin and became famous in Europe. His works became popular in Europe and were contained into the basic subjects of the schools.

Lesson 45 Essay
The collapse of the Roman Empire led to the creation of a wide variety of glass. It caused trade and knowledge to spread throughout Europe. Roman glass was high-quality but skills got worse in Northern Europe. When the Roman Empire collapsed, glass making slowly improved. It brought out more creativity to explore new ways for glass making, such as using new ingredients. The Romans recycled their old canton recipe and experimented with different sources of ash. They discovered new colored glass thousands of years later. They also discovered additives, such as salt elements, that produced different colors. Stained glass windows increased demand for colored glass. They installed new colored stained glass windows in churches. Roman glass making skills increased all over the Middle Ages.

Lesson 40
Farms and Food
If I could change one thing about the world it would be to add more farms. Why I think this is a good idea is because you can produce more food for restaurants and households. Another reason why I think this is a good idea is because it can also help people be much healthier. The last reason I think this is a good idea is because it helps the farms raise more money and have more customers so they can stay in business.
Lesson 40 Essay
My favorite thing I have learned in history are the Arabic and Roman numerals. The Arabic numerals are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. We use them to make multi-digit numbers like 23, 65, 89, 123 and beyond. We use Arabic numerals every day when we are multiplying, dividing, subtracting, and adding. Roman numerals are another way of writing numbers. The Roman numerals are I, V, X, L, and more. The letter “I” means one, “V” means five, “X” means ten, and “L” means 50. Roman numerals are sometimes used to number pages and chapters. Before Arabic numerals the Romans used Roman numerals to write numbers. Why Arabic and Roman numerals are my favorite is because both are used for math.
