Can you pull a car with cordage made just from a plant? We put it to the test! This clip with Jefferson Patterson Park and Museum's Educator Nate Salzman provides a simple demonstration proving that a cell's microscopic structure affects its macroscopic properties. Included in the video is the very simple method needed to produce and test cordage from yucca leaves on your own.
If you're thinking of using this in a classroom, considering pairing this exploration of cells' structures with an engineering challenge! Yucca fiber can be made without boiling the leaves, if needed: students can either pound/mash leaves to isolate fibers or fibers can be peeled from wet leaves and used while still "green" (any cordage made from green fibers will loosen as it dries, however).
This resource is part of JPPM’s open educational resources project providing education content from our in-house educators, horticulturalists, curators, and conservationists at our 560 acre public park. The grounds have provided a home for different peoples for over 10,000 years and includes extensive archaeological sites, multiple ecosystems, and a 1930s farmstead designed by architect Gertrude Sawyer for the park’s namesake, Jefferson Patterson.
