This document provides teaching materials and activities for lessons on water and solutions. It includes: 1. Word lists and definitions for key scientific terms related to the physical characteristics and composition of water, such as melting point, boiling point, and electrolysis. 2. Details on activities to reinforce vocabulary, including word puzzles, jumbles, and crossword puzzles using the terms. 3. Instructions for teachers on distributing materials, having students complete the activities, and going over answers to check understanding. The goal is to help students learn and understand important scientific vocabulary through engaging classroom exercises on topics like the physical properties and molecular structure of water.

1. 3.0 GLOSSARY
