This document outlines 5 science experiments on materials and their properties. Experiment 1 is on rusting and involves a question, hypothesis, materials, procedure, observations, and conclusion. Experiment 2 is on dissolving in water and follows the same format. Experiment 3 and 5 are also experiments involving a question, hypothesis, materials, procedure, observations, and conclusion. Experiment 4 involves a table categorizing different changes as desirable, undesirable, reversible, or irreversible. The document concludes with what the student learned from each experiment.
