Welcome to Physical Science 112 — General Course I. Class meets from 8:35 am until 11:00 am on Monday and Wednesday in Room 3833. Class begins Monday, January 14th. This is a general science course for non-science majors. We spend the first half of the course studying Physics. We spend the second half of the course studying Chemistry. Both subjects are approached conceptually with a minimum of mathematics.

Welcome to my website. Here you will find materials from all of my classes and many other resources to help you learn. My experience includes the teaching of many subjects: astronomy, chemistry, geology, meteorology, conceptual physics, web development and design, programming, electronics, urban gardening, and food chemistry.

Education is a difficult field to belong to these days. On one hand information is easy to access. If you want to learn something new you can probably find excellent instructions via videos and other media on the Internet - so why come to a classroom? It is an important question to ask. Enrolling in college classes involves you with a community of learners. Note the word community. Please ask yourself: what does it mean to belong to a class - and to participate in a shared experience of learning?

My approach to teaching is multi-faceted. It seems to me that authentic experiences, tactile and immediate, are critical to building a connection between the learner and the subject. Certainly a love of the subject helps! Sometimes learners need structure and goals set externally to keep them moving through material. Sometimes learners need to be inspired and motivated.

Based on my years as an educator, my own intense curiosity about the world, my passion for learning and a commitment to your success I hope to provide you with an exceptional learning experience.


I realize books are expensive. These two books are excellent references. If you are planning a career in elementary or high school education I think you should buy them. You do not need them both yet. If you can afford it - but the first one now. There is a cheaper alternative to the first book, a paperback book by the same author, Paul Hewitt, “Touch This! Conceptual Physics for Everyone.” It is not a text book but it does cover the main ideas. It is about $10 from If you are taking this course as a prerequisite for graduation then you will be able to get by with the paperback book for now. I will put notes on the website and point you to links on the Internet.
