Teacher's field guide

What Students Need to Do: Students trace how farming methods spread when people move and share knowledge. They explain how tools changed farm work over time.
What Mastery Looks Like: A student can explain how irrigation methods spread from North Africa to medieval Spain. They can compare a canal with a modern drip line and explain how each waters crops.
Common Misconceptions: Students may confuse the spread of a crop with the spread of a farming method. They may assume a new tool replaces every older method at once.
How to Assess It: Exit ticket: Farmers in medieval Spain adopt irrigation methods from North Africa. Later farmers install drip lines. Which change shows shared knowledge, which shows new technology, and how does each help?

Lesson moves

Build a foil canal and a punctured-straw drip line over two trays of soil; compare where the water reaches.
Ask: When farmers in medieval Spain adopted irrigation methods from North Africa, was that shared knowledge or a new invention? Explain.
Give pairs cards describing irrigation spreading to Spain and tractors replacing animal plows; have them sort shared methods from new tools.
Show a photo of drip lines on a farm; ask which water problem they solve compared with a canal.
