State of matter science quiz, 2nd, 3rd, 4th grades, learn about changes in states solid, liquid & gas, change processes: evaporation, condensation, melting, freezing, solidification. Students will explain what happens to objects if subjected to specific conditions. They will determine if their states will change e.g if ice is heated it will melt and become water. If paint is left to dry, it will become solid, if water vapor is cooled sufficiently it will become water. This quiz contains multiple choice questions and in some cases pictures models to illustrate processes and changes. This review activity will be useful for teachers and parents of students in 2nd, 3rd and 4th grades.
