Is Lesson Plan Middle School

Sensemaking Checklist

Lesson Overview

In today's Daily Do, students engage in science and engineering practices and use patterns as a thinking tool to make sense of the Black Smoker Chimney phenomenon. Students investigate how a solid forms from the mixing of two liquids. Students use the science ideas they develop to help explain how chimneys form at hydrothermal vents.
