Welcome to Chemistry!

So Cool!

Welcome to Chemistry!  I'm so excited to get started on another school year with you in my class.   This is my 16th year of teaching (that sounds like a long time).  I love my job because every year is so different and always a lot of fun.  You, my dear chemistry students, make my days interesting, fun, and (yes) challenging.  This year will be another great adventure in my quest for new and exciting chemistry experiences.



You started off with a fun exploration of an interesting system of milk, food coloring, and dish soap.  I encourage you to try this at home to impress and amuse your family.  You conducted your first controlled experiment today when you changed one component of the system and then observed the effect of that change.  Now I want you to think about what caused the system to change.

Take a look at this short video that gives one possible explanation of the phenomenon of the milk and food coloring.

Now I want you to think about your experiment.  Do your results support or contradict the explanation you just saw?  Post a comment about how your results support or disclaim the milk experiment explanation.

P.S.  Sorry guys, I didn't take any pictures of you this time.
