In this unit, students use hands-on experiences with blocks, balloons, and beakers to identify the distinctive properties of the three common states of matter. With a variety of lab tools, the students observe, explore, and measure solids, liquids, and gases, and investigate the processes by which one changes into the other. As students conduct melting, freezing,evaporation and condensation experiments, they learn the importance of controlling variables and keeping records.
