Bite Me (July / August 2003)
This Guide contains project ideas, short answer, extended response, fill-in, and true/false with correction. The variation is designed to have the students think critically, as well as to test their comprehension. An answer key to the short answer sections can be found at the end of the guide.
Extended Response: Comprehension & Critical Thinking
The questions below can be used as written, simply answered in complete sentences, or easily transformed into longer essay (ELA) style questions, or even research topics. In any case, have the students support their answers with details from the test or use critical thinking skills to create a thorough and interesting answer. Consider the level of your students when deciding how to use the questions.

______4. The importance of teeth in the fossils record of hominid evolution lies in their abundance.
______5. Dog and human teeth have similar structure.
______6. Human teeth, like those of other mammals, are composed of three very durable tissues.
______7. The three durable tissues are called cementum, dentine, and roots.

"When Pain Ruled" p. 18-19
- Explain how Zhao Mo's architects constructed his tomb.
- Activity: Think of materials you can use in the classroom or at home (blocks, legos, Lincoln logs, etc.) to make a model of the tomb. Use the information from the article to direct your construction.
- What items found in the tomb confirmed Zhao Mo's support of trade?
- Combine facts from the article and your imagination to create your own theory about why there were elephant tusks in the tomb.
The ancients used toothpicks, likely made from twigs, to clean between their teeth. Toothpaste was made from various abrasive ingredients. Cavities were filled with gold, silver, wax, or gum from trees. Brainstorm with a partner to make a list of other things that the ancient civilizations could have used as substitutions for cleaning instruments, toothpaste, and cavity fillers. Keep in mind the substances that were available at this time. Be creative! Share your list with the others in your class . . . are any of your ideas the same?

Write a letter (proper friendly letter format) to your archeologist friend in the U.S. explaining what you have discovered.
