By Phase By Day Calendar
Launch
Students will launch the erosion project by noticing how wind and water change land in San Diego, observing a short hands-on demo, learning from a community expert connection, and creating an early engineering design notebook entry that names the problem, possible materials, and what a successful model should do.

Launch & Define
Students will connect erosion to San Diego places, define the design problem with simple criteria and constraints, study how existing materials help hold soil in place, and prepare a team design brief for an erosion-blocking model.

Build & Prototype
Students will build a first erosion-control prototype, use simple wind or water tests to gather evidence, record before-and-after changes with drawings or photos, and use peer feedback to plan their next revision.

Revise & Retest
Students will study evidence from their first erosion tests, revise one feature of their model at a time, retest with the same wind or water procedures, and explain which changes helped keep soil from blowing or washing away.
