Ten Interesting Facts . . . . Worms

Ten Interesting Facts about Worms

Earthworm1. Migration

Worms have not always lived in America. Many scientists believe that worms living in America were killed during the Ice Age. This was approximately 10,000 to 50,000 years ago. During the 1600’s and 1700’s, Europeans brought worms to North America as they were forming the colonies. This was quite by accident. Colonists wanted to bring plants from their native countries to the New World. The worms were living in the dirt that surrounded the plants. Just think, if worms had not been brought to the New World, American soil would be very poor.

2. Harmful?

Some people think worms are bad for the garden. They have seen damage created by pests. Cockroaches, termites, beetles, and silverfish love to eat paper and the binding of books. Malaria is spread to thousands of people each year through mosquito bites. Fleas carry bacteria which can cause humans to get sick when bitten. It’s no wonder that people think earthworms are harmful as well.

3. Size

Earthworms vary greatly in size. Some are only an inch long while others are many feet long. The Australian giant earthworms average about ten feet in length. The largest earthworm ever found measured 22 feet from anterior to posterior. In North America, the largest common night crawlers are only about 12 inches.

4. Behavior

Some earthworms receive their names based on their behavior. The night crawler comes up to the surface at night. The angleworm is often used for bait by fisherman. The rain worm leaves the water soaked soil after storms.

5. Breathing

Earthworms breathe through their skin.

6. Young

Baby worms hatch from eggs fully formed. They can live up to eight years although one to two years is the norm.

7. Food

Earthworms eat mostly leaves. Their digestive system is a tube that runs from their mouths to the rear portion of their bodies. Earthworms move nutrients such as potassium and nitrogen into the soil. In fact, some gardeners buy earthworms and place them in their gardens.

8. Benefits

While earthworms are extremely beneficial to farmlands, they can cause harm to northern forests. Northern forests have a cushion of decaying leaves called duff. This is beneficial to young trees and insects. When earthworms move through the duff, they eat it up leaving young saplings and insects without needed nutrients.

9. Movement

Hairs on each segment of the earthworm help it move through the soil.

10. Species

There are about 6,000 species of worms.

Activities for Teaching Setting in Literature

Teaching Setting

Activity #1

I often teach the setting of a story by discussing genres. I ask students to name where and when a specific genre takes place.

 

Here is an example:

Science Fiction  >> Outer Space  >> Future

Fairy Tales >> Magical Kingdom  >> Usually Past

Realistic Fiction >> Real Locations >> Usually Present

Myth >> Heaven and Earth  >> Past

Historical Fiction >> Real Location >> Past

 

Activity #2

Next we use vivid imagery to describe a setting. I really stress the “Show, Don’t Tell” concept. [You might enjoy reading this post on Show, Don’t Tell.] I have students use a chart with the five senses listed across the top. Under each category, I ask students to use short phrases to describe what a character would experience in the location.

 

See

Feel Smell Taste Hear

 

Activity #3

Next students work in small groups to examine settings in picture books. Here is a list of Picture Books with Well Developed Settings from readwritethink. Students use the Show, Don’t Tell method of describing the setting in their picture book.

 

These free “Printable Charts for Setting” may be used with Activity 3. You can download the anchor chart of your choice by clicking on the images below. Printing instructions are found below the images.

 

 Free Beach Setting Anchor Chart  Free Mountain Setting Anchor Chart
 Free City Setting Anchor Chart  Free Forest Setting Anchor Chart
 Free Blank Setting Anchor Chart

This blank setting anchor chart is editable. It will download in PowerPoint. If you would like to keep the same font that says, “Setting,” click anywhere next to the word setting in the text box and just start typing. Delete the old text AFTER you have your new text completed.

 

Printing Instructions

Adobe Reader

With Adobe Reader 10 or newer, you can print posters by splitting the document across multiple sheets of paper called tiles. After printing, you piece the tiles together. If you have an older version of Adobe Reader, you can update to a newer version with a free download here: http://get.adobe.com/reader/

Printing Instructions

  1. Choose File > Print
  2. A pop-up menu will open. Select the “Poster” option under “Page Sizing & Handling.” The poster is set to print 20 by 30 inches. This will tile over 8 pieces of paper. This size fits perfectly on the standard 22 by 32 inch flip chart. If you select “Size” in place of “Poster,” your poster will fit on a standard 8 1/2 by 11 inch piece of paper.

 

Additional Resources

If you are looking for additional resources, you might like to take a look at “Characters and Settings.” This resource contains mini posters, foldable graphic organizers, and activities to help teach about characters and settings.
