Now let's look at the information that Regan found. Regan wants to answer this question in his paper: How are arrowheads made, and can anyone make one? In his introduction, Regan says

Finally, I did some research on arrowheads to find out how the Indians used to make them and if I could make one now. I learned that making arrowheads, which is called flint knapping, was once only known to Native Americans in this country. But today, many people besides Native Americans make arrowheads. Flint knapping has been done for millions of years, and you, too, can learn how to make arrowheads.

When he writes his research report, Regan will need to show his readers two things: (1) flint knapping has been done for a very long time and used to be a skill known only to native peoples, and (2) anyone can learn to do it--if they have the patience for it. To see Regan's reasoning--the way he will try to convince readers to try flint knapping, click the Read Me button below, and answer the questions on Regan's notes. (The questions will help you see Regan's reasoning.)

 

What are Regan's first two sources?

  1. web sites
  2. books
  3. magazines

The first two sources in Regan's notes are books--one from a library and one that Regan had at home.

When Regan looks back at his notes for source 2 (the book Early Humans), what reason could he see there?

  1. Flint has been used to make pointed objects for millions of years--because it's easy to work with.
  2. Flintnapping is much more fun that other outdoor skills like whittling or woodcarving.
  3. Ancient people in the Americas had a hard time finding flint for their tools and weapons.

Early Humans provides information about why flint is used to make arrowheads and other projectiles.

How can his notes on source 2 support Regan's idea that anyone can make arrowheads?

  1. It goes into a lot of detail about the many steps required to make an arrowhead.
  2. It describes flintknapping as a process with just three steps.
  3. It explains all the types of people who can do flintknapping.

Regan's notes on Early Humans contains a list of the three steps required to make an arrowhead.

What reason does source 4 give Regan for saying that flintknapping is a popular activity?

  1. Flintknapping is done in all parts of the United States--north, south, east, and west.
  2. People in Michigan enjoying making arrowheads more than other people.
  3. There is at least one statewide "club" devoted to flintknapping, and it's a very active club.

The web site for the Michigan Flintknappers shows that there are enough people who like flintknapping to form at least one state-wide club.

How might source 7 (from an archeology web site) help Regan explain how arrowheads are made?

  1. It explains what happens to flintknapping rocks when they are hit with hard and soft hammers.
  2. It lists the steps that flintknappers use to create arrowheads.
  3. It describes what types of rocks are most often used in flintknapping.

If readers can imagine what happens to rocks when the rocks are hit with hammers, they will understand a lot about how arrowheads are made.
