This unit from the Scripps Classroom Connection begins by teaching students the methods used by scientists to study the seafloor, with various seafloor features presented for analysis. Learners then perform a mapping and graphing activity meant to familiarize them with the range of depths and features on the seafloor. This activity is listed under "Overview Week 1: Daily Lessons and Activities," and is labeled "Day 2: Seafloor Shape and Features" on the main page.
