An introductory chemistry course

Welcome to Mr. Ehinger’s Chemistry! On this site, you will (eventually) find a complete introductory course in chemistry. This course will most probably not fit exactly with your specific syllabus, but if you follow this video course, you will still recieve a solid foundation in chemistry, from the birth of chemistry and the atom model to modern biochemistry.

How to use these videos

Now, about these videos. You really shouldn’t just watch and enjoy them. If you really want to learn, you must use a pen and paper too. Take notes from everything written on the screen and copy the simple drawings too. You will see that these kinds of notes and drawings are exactly what you will be required to produce on your exams. So, by taking notes from these videos, you prepare yourself for your exams.

Questions? Feedback?

If you have any questions or feedback, please feel free to post them in the comments section of each video. I can’t promise that I will always answer every question, but I will do my very best. 

Once again, welcome to the wonderful world of chemistry!
