Students are often shocked when I bring in physiology, general biology, physics, and other topics into a chemistry lesson. Perhaps the problem is generated from the fact that we think of disciplines as separate silos. If you're a chemist, you can't be a physicist or a biologist. Rubbish! Chemistry is the basis of so many technologies that we enjoy in life. A solid grasp of the subject will make a student better in a different field.
Enjoy the journey, and see where the connections take you. In the end, you'll be glad that you removed the boundaries to see chemistry in all its glory.
