Why Teach Science?

  1. Science should be taught to everyone so that everyone can appreciate the complexity and beauty of nature.
  2. Science should be taught to everyone because great scientists can become great only if they become scientists first.
  3. Science should be taught to everyone because understanding science is the key to understanding technology. And technology has become a force in society which, if we are not careful, will control our future.
  4. Doing challenging work of any kind trains the brain. Studying science provides students with an opportunity to think deeply about complex systems. Specific skills and concepts may or may not have long-term application but the ability to think critically and synthesize complex information is universally applicable.

Not every student in an art class becomes an artist. Not every student in a science class becomes a scientist. But everyone should learn to understand the beautiful and everyone should learn to understand the world around them.

Science, at its best, is doubt instilled in a person as a virtue. Certainty is stagnation: the human imagination is no match for the imagination of nature. Nature does not give up her secrets easily. Critical thinking and careful comparison are essential toward building the constantly improving models built by the methods of science.


Mr. Keller’s Motto

Think, Reflect, Learn

Correct answers matter less than critical thinking. If you think carefully, and work hard, correct answers will come. The important thing is the thinking. If you think carefully and reflect on your work you will see for yourself whether your answers are correct or not. FIO

Important note regarding printing

Before printing turn off the optional header and footer information. Also, make the left margin 0.75 in (1.9 cm) and the other margins 0.5 in (1.3 cm) so that the page breaks I built into the pages work as intended. Use only Internet Explorer to print as Netscape and Firefox both implement the page code a bit differently and I haven't optimized the pages for those browsers. My apologies if you are using a Mac: I cannot guarantee that you will be able to print these pages as I intended.

Some of the files are PDFs and you need the Acrobat Reader available from Adobe. Some files are also MS Word 97 or RTF documents, which just about anyone should be able to view. If you have trouble, try going to www.microsoft.com to download the Word Viewer.

Writing Scientific Explanations

In my courses you will be asked to write well-reasoned scientific explanations. In other words, you will develop correct theories about the world and write them down.
Overview of Explanations

Group Work Defined

Working in small groups to solve problems is a great way to learn science. Here are a few documents to give group work some shape and definition so that it can be a self-regulating learning tool:

Student Quotes

Students write some very funny things at times. Sometimes they even realize it at the time. All of the quotes on this page are verbatim from real student papers. Names have been withheld to protect the innocent.

Science and Pseudoscience
Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What have we to offer in exchange? Uncertainty! Insecurity!

—Isaac Asimov

Hofstadter’s Law
It always takes longer than you think it’s going to take, even when you take into account Hofstadter’s Law.

—Douglas Hofstadter

The Unknown
It ain’t what you don’t know that gets you in trouble. It’s what you know for sure that just ain’t so.

—Mark Twain

Understanding the Universe
“The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.”

—Steven Weinberg

“Magic, as practiced by performing magicians, is the art of making people see things that didn’t happen and miss seeing what did. Teaching science is the art of making students see things they never suspected to exist and recognize when they seem to see things that do not exist.”

—Aaron Keller
