During Reading

Student Reading
Introduce the worksheet. Explain to students what the worksheet requires them to do.
Say: You will need to read the text Volcanoes and then fill in the spaces on this worksheet.
It may be easier to read a chapter and fill in the area relating to that chapter as you go.
Under each heading, you will need to write some facts about that particular volcano. You will also need to summarize the most important facts and write them in your own words.

After Reading

Building Comprehension
Refer to the questions of each section of the comprehension worksheet. Ask students to share their summaries of each section. Also ask them to restate facts and details in their own words.
Ask: Who would like to share their findings on Vesuvius? Who would like to share their findings on Mt. St. Helens? Who would like to share their findings on Mt. Etna? Who would like to share their findings on The Hawaiian Islands? Who would like to share their findings on Wizard Island, Crater Lake? Is there anything else anyone wants to share?

Word Work
Prefixes, suffixes, and root words
Ask students to define the words prefix, suffix, and root word. Explain that a root word is the a word that can stand alone. A prefix is a group of letters that can be added on to the front of a word to change its meaning. A suffix is a group of letters that can be added to the end of a word to change its meaning.

The study of applied science - technology
Introduce the second worksheet.
Explain that is related to the work covered on homophones and -ology words.

Title - Tells what the diagram is about.
Labels - Identifies different parts of the diagram Using these features, have students suggest information they can see in the diagram.

Ask: Using the features we have talked about, what information can you see in this diagram?

Writing Link
Have students choose one -ology word to research further. They may need to visit the library or use the Internet or a dictionary. Have them write up the word, a definition of the word, and any other information they find.
