Water and Ice

A lesson plan for grade 2 Science
The purpose of this lesson is to use observation, measurement, and communication skills to describe change. In this lesson, students will observe, measure, and describe change in water as it changes state. As part of the investigation, students will take simple measurements using a thermometer and a balance and cubes. Research suggests that students at this age often fail to conserve the weight and volume of objects taking shape. (see Research) Some attempt has been made to address this misconception, but further instruction will be necessary. This lesson is most appropriate for a kindergarten or first grade class, and does require some advance preparation (see Motivation).
