If Fred has made math understandable and fun for your student, you’ll find him a great teacher for Chemistry! Fred says: This is the high school chemistry course that I wish I had when I was first studying chemistry. Several studies have shown that students who have had a high school chemistry course—like this book—do much better learning college-level chemistry. The traditional way to teach chem (and math and physics and biology) is have the student memorize thousands of facts. Some chem textbooks are like telephone books. One of them is actually 1200 pages long and costs more than $200. If you were teaching chem to a computer, this approach would be perfect. Computers can memorize (and retain) a million facts without breaking into a sweat. The trouble is that many chemistry students are human. Opening a traditional chem textbook at random I found, “Gallium and In occur only in traces in Al and Zn ores. Thallium, also a rare element, is recovered from flue ducts from the roasting of pyrite and other sulfide ores.” That’s nice, but hundreds and hundreds of pages of fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact, fact do not add any meaning to your life. And even if you do memorize mountains of chem facts, you will forget 90% of them a month after you finish the course.
Life of Fred: Chemistry requires no sitting down and memorizing. You will learn that H stands for hydrogen and Na for sodium because you will be using those abbreviations often enough. All of the exercises are open book.
WHAT YOU WILL NEED:
A scientific calculator that has keys marked sin, cos, log, and ln. They cost less than $20 and will also be used in advanced algebra, trig, and calculus. This is not the super expen$ive graphing calculator. Enough of beginning algebra that you know that 10–3 means
Enough of beginning algebra that you know that 10–3 means 1 10 3 and can solve 9.444 = 3.222x + 3, and know that (4 4 )(4 5 ) does not equal 4 2 0 .
