Silt in the River Garden
The floating lettuce beds are wilting at noon. Trace the cause before you replace the wrong valve.
Student researcher Amina Yusuf joins Dr. Priya Raman and engineer Mateo Cruz at Canal Basin Three. The lettuce leaves in the river garden are drooping even though the water pump is running. Amina must listen to the sensor readout, inspect the intake filter log, and explain what the mesh filter can and cannot fix.
Communicative Objective
Students explain a cause-and-effect chain in an environmental system and state the physical limit of an engineering solution.
Interactive Mechanics & Vocabulary
Bench Tool: Cause & Effect Matrix (2 story forks). Words: sediment, filter, dissolved, intake, oxygen, cause.

Two Filters, One Intake Pipe
Fine silt clogs the single fine mesh in twenty minutes. Compare a single screen with a two-stage gravel-and-mesh design.
After Tuesday's storm, Mateo Cruz notices that a single 100-micron wire mesh clogs again every twenty minutes because coarse river sand and fine clay hit the screen at the same time. Amina and Dr. Raman test a two-stage filter that places a coarse pebble bed in front of the fine wire mesh. Students compare the two designs and argue for the two-stage system using flow-duration data.
Communicative Objective
Students compare two engineering designs using quantitative test data and argue why a two-stage filter outperforms a single fine screen.
