In this lesson, students will cooperatively measure the mass and volume of three different-colored crayons as a solid. After recording measurements, students will place their crayons in molds in order to change the state of matter from a solid to a liquid through heating. The teacher will pour the liquefied crayon into a graduated cylinder to measure the volume. Following the measurements recording, the liquid will be poured back into the molds and placed in a cool/shaded environment so the crayons will change back into a solid state. Once the crayons re-solidify, the students will take their student-made, tie-dye crayon out of the mold and re-measure it. Lastly, the students will measure and compare their final measurements to the initial measurements.
