1 What your class asks
This lesson asks you to describe what plants need, such as air, water, light, heat, nutrients and space, and to name conditions that can threaten their survival. The museum offers one part: the practical handbook of an Andalusi farmer who relates land, water and season to plants. The other needs your class will study by direct observation. 1
Curriculum expectations, with their official codes
- B2.1 describe the basic needs of plants, including the need for air, water, light, heat, nutrients, and space, and identify environmental conditions that may threaten plant survival
2 The lesson
What changes when the water or the ground changes?
Picture one plant in two different kinds of ground, or with two different waters. Which of its needs changes first? How could you tell by observing?
Go deeper
In his practical handbook, Ibn Bassal has a chapter on water. It tells apart rain, rivers, springs and wells, then discusses how each relates to plants, to what is left on the surface and to the season 2. He does not give all river water one character: the record says he describes how it varies in dryness, moisture, roughness and softness 2 3. The record adds that these are descriptions from an older account of nature, not chemical analyses 2.
Think about it
Ibn Bassal did not say that all river water is alike. Why might a farmer who treats every water the same grow worse plants than a farmer who notices the differences?
Into the museum
- Ibn Bassal's soil, water and crop assessment: the four waters and the ten kinds of land he separated.
- Ibn Bassal: the Andalusi agronomist and where his work was set.
- Agriculture in Islam: how a modern author presents farming as a source of food.
Try this
Read the record Ibn Bassal's linked soil, water and crop assessment and list the water sources and land types it names; beside each, write a plant need it might affect.

Compare with the card
Which water, which land?. In Al-Qasd wa-l-bayan, Ibn Bassal does not treat garden land as one substance needing the same water and work in every season. He distinguishes four water sources, among them rain, rivers, springs and wells, and ten practical land types, and relates what he observes to the season, the plants and the work the land needs. These are older descriptions, not modern laboratory measurements. Which of a plant's needs do his questions about water and land touch?
