Apologia Chemistry: Boyle's Law Module 12

Module 12 is about Gas Laws.  Start with lab!  I like to start with Boyle's Law Lab using pipers, food coloring, tap water, and books.  (Don't say we never use our textbooks!)  The instructions above and video below demonstrate the procedure with a pinch clamp.  My colleague, Dave Rickman, heat sealed the pipets for this lab.  We added the food coloring and sealed the ends with a sterno lamp.  The kids record pressure in books and volume in millimeters.  They sealed 10 or so pipets to get a good average to graph.  Once they collected the data, the kids graph the pressure and volume data with the graphing calculator and summarize the relationship between pressure and volume.  This gives them another opportunity to use the graphing calculator's stat function, too.
