We’re Not Alone

Introduction

Take  A Journey to Study Parasitic Relationships (Grades 9-12)

 A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host.

A few examples of parasites are tapeworms, fleas, and barnacles. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host's partly digested food, depriving the host of nutrients. Fleas harm their hosts, such as dogs, by biting their skin, sucking their blood, and causing them to itch. The fleas, in turn, get food and a warm home. Barnacles, which live on the bodies of whales, do not seriously harm their hosts, but they do itch and are annoying.

Usually, although parasites harm their hosts, it is in the parasite's best interest not to kill the host, because it relies on the host's body and body functions, such as digestion or blood circulation, to live.

Some parasitic animals attack plants. Aphids are insects that eat the sap from the plants on which they live. Parasitic plants and fungi can attack animals. A fungus causes lumpy jaw, a disease that injures the jaws of cattle and hogs. There are also parasitic plants and fungi that attack other plants and fungi. A parasitic fungus causes wheat rust and the downy mildew fungus attacks fruit and vegetables. Some scientists say that one-celled bacteria and viruses that live in animals and harm them, such as those that cause the common cold, are parasites as well. However, they are still considered different from other parasites. Many types of parasites carry and transmit disease. Lyme disease is transmitted by deer ticks.

A parasite and its host evolve together. The parasite adapts to its environment by living in and using the host in ways that harm it. Hosts also develop ways of getting rid of or protecting themselves from parasites. For example, they can scratch away ticks. Some hosts also build a symbiotic relationship with another organism that helps to get rid of the parasite. Recent studies have suggested that parasitic worms may provide unexpected benefits to the humans they colonize, helping allergy sufferers by calming the allergic response. Have students research this unexpected upside to the worm-human symbiotic relationship

Task

Develop an understanding of parasitic relationships affect our world and how parasites co-evolve with their hosts to relate to the characters in the book called Peeps by Scott Westerfield.

Process

1. Read the Book Peeps by Scott Westerfield

2. Review the following Links about Parasitism

3. Complete the TIC TAC TOE worksheet by choosing from the following choices below.

1.Research parasitic symbiotic relationships. Choose one of these relationships that is most interesting such as worm-human interactions.

2. Create a parasite and host life cycle poster for a the parasite of your choice (not the same as item #1)

3. Create a poster to identify major parasites that can affects humans

4. Students design an illustration, essay, or multimedia work piece to describe how one of the researched parasitic symbiotic relationships has evolved over time.

5. Choose a current event related to parasites and write a letter or blog to the editor of your local paper about the impact this event is having on the world.

6. Design a vocabulary collage with pictures and symbols to show relationships for the following terms. 

Parasite

Intermediate Host

Ecosystem

Environment
