Plant Xylem Capillary Action Hydro-Transport STEM Lab (BIO05) | Middle School Life Science (Grades 6-8)

? Plant Xylem Capillary Action Hydro-Transport STEM Lab (BIO05)

Explore vascular plant anatomy, xylem tissue transport mechanics, capillary action, fluid adhesion vs. cohesion, and transpiration pull! The Plant Xylem Capillary Action Hydro-Transport STEM Lab (BIO05) challenges middle school student teams to act as botanical bioengineers, testing natural plant stems and capillary models to measure how vessel diameter drives fluid ascension rates.

Students explore xylem vascular tissue, hydrogen bonding adhesion and cohesion, transpiration evaporation suction, tube diameter mechanics, and fluid transport rate math!
