This lab activity is meant to follow up the Predicting Temperature Changes Lab. The previous lab mixes different temperatures of water only. This lab mixes water with another substance (metal) and demonstrates the pattern from the previous lab doesn't always hold true. This lab was originally designed for a 9th grade physical science class but could be used in middle grades or even a physics class with some modification (suggestions for modification included).
This packet includes a student handout, instructions, and teacher notes.
