I use this lab with 7 stations as a starter to get the students think and question about the various properties of matter. The students are encouraged to observe, analyze, and interpret the best of their abilities even if they cannot get the correct answer. They are encouraged to interpret to the best of their abilities.
The students are to work in small groups or with a partner and there are key words for the students to use to help them with their explanations.
