Descriptions of daily activities and graded assignments can be found through the blog tabs on the left.

If you are here to explore, check out the "References" tab on the left. If your are a student, be sure to read your class blog to make sure you are caught up on the class activities as you are expected to check your class blog (see tabs on the left) each day they are absent or feel you missed something in class, and for important support information.

Need extra help with your school subjects, perhaps some on-line tutoring? Try,, or a host of other sites.

Now for a financial plea: Please consider donating materials or money to the classroom. Tax deductible money can be donated to my class through Donor' . I typically spend over $500 per year of my own money on classroom supplies that include pens, pencils, copy paper, safety glasses, band-aids, markers, aluminum foil, cups, saran wrap, plastic silverware, tissues, paper towels, and batteries (AA, AAA, 9V). Such items will be gladly accepted and will allow me to use my limited resources on other classroom needs such as labs and demonstrations.

I have a sign in my classroom that reads "Math is the tool of the scientist". You can pass my class with limited math skill but to become an engineer or scientist or just enrich your understanding of the world, you better develop great math skills. Its never too late to develop these skills; so, if you want to refresh or improved some of your math and science skills, in addition to the tutoring sites mentioned above, try these sites dedicated to math:, and

IMPORTANT: All students must have a scientific calculator for class; one that has the ability to use scientific notation and logarithms. Students should use class time to become experts at their personal calculator when possible, (GET A CALCULATOR, KEEP IT HANDY, AND USE IT!!). I've seen cheap dollar store scientific calculators and numerous acceptable brands are sold at retail stores. The TI-30 varieties are an inexpensive option or a TI-84 graphing calculator can be used for more advanced mathematics. Used graphing scientific calculators like the TI-73's TI-82's, TI-83's, and TI-84's can be purchased on-line for as little as $5. Cell phones calculators are NOT permitted for exams and forbidden on college board exams (See for the college board calculator standards:
