1 What your class asks
This lesson asks you to analyse what different communities have contributed to science and technology. The museum offers three examples from the medieval Muslim world: an experiment on light, a way of writing numbers and a pump turned by water. Contributions from other communities your class must bring from elsewhere. 1
Curriculum expectations, with their official codes

A thought to carry into the lesson.
3 The lesson
What did each person start from?
For each example, look at what was already known and at what was added. The records themselves say these were improvements within older traditions, so look for the words that show what was new.
Go deeper
Al-Khwarizmi wrote a book in Baghdad on algorism, counting with the Indian numerals. Through it, the record says, the Indian numerals and the decimal system entered the Islamic world 2. The record offers a modern example of place value: the two represents two hundred and the eight represents eight units, while zero occupies the tens place in 208 2. It also says he did not invent the numerals; he transmitted them and taught reckoning with them 2. His Arabic book is lost, but a twelfth-century Latin translation survives 2.
Think about it
Al-Khwarizmi did not invent the numerals; he carried them and taught people how to count with them. Does a person who teaches an idea to many people help science as much as the person who first thought of it, and why?
Into the museum
- Algorism: how numbers are written and worked by place, and where the word algorithm comes from.
- Ibn al-Haytham's dark room: how a familiar sight, light through a hole, became a test that can be repeated.
- al-Jazari's double-piston pump: a pump driven by flowing water, and the model that helps explain it.
Try this
Choose one of the three records: Ibn al-Haytham's dark room, Algorism or al-Jazari's pump. Draw a line and mark on it what was already known and what the record says was added.

5 Check yourself
Nothing here is marked or sent anywhere. It is for you.
In your own words: what does Ibn al-Haytham's dark room (the camera obscura experiments) have to do with this lesson?
Compare with the card
A dark room that tested light. In his Book of Optics, Ibn al-Haytham let the light of the sun, the moon, the stars and a fire into a dark room through a small hole, followed it across the opposite wall, and laid a ruler along its path, finding it straight. The museum records this as an improvement: he did not discover that light passes through a hole, but turned a familiar sight into a repeatable test. What did his test add to what people already saw?
In your own words: what does Algorism (reckoning with Indian decimal numerals in al-Khwarizmi's book of arithmetic) have to do with this lesson?
Compare with the card
A word that came from a name. Muhammad ibn Musa al-Khwarizmi wrote a book in Baghdad on reckoning with nine Indian numerals and a zero, through which the Indian numerals and the decimal system entered the Islamic world. Its Arabic original is lost; a Latin translation survives that opens 'Dixit Algorizmi', 'al-Khwarizmi said', and from his name comes the word 'algorithm'. Whose knowledge travelled in this book, and whose hands carried it on?
