This is a lab that I created because my students enjoyed slime and had expressed interest in making it at school. I used this as a way to launch into the scientific process and matter. We discussed the phases of matter as ingredients were measured and mixed together. This file is only one kind of slime. The Butter Slime is one that does not work. I included it in my lessons so that my students could experience the full scientific method. While I did not have them record anything about what we could have done differently, I used this as a launch into a think aloud of the process.
