Instructional Procedures

1. Identify the pages students will need to read and direct them to those pages.
2. Ask them to look at the student page and read the introduction together. Tell them that their conclusion will not be found in their books, they will have to look at their data.
3. Give students times to collect the data and fill in their tables.
4. Ask students to work in groups to create the newscast. It can be presented to the class, video taped or just written.
