Instructions:

I. Teaching and Learning Strategy: Dichotomous Keys and Classification

1. Set up approximately 30 stations in the room.2. Each station should have one example specimen from the six kingdoms.

3. Students will need to take out their field notebook, journal, etc.

4. They can title their paper, Using a Dichotomous Key to Classify5. Give each student a kingdoms dichotomous key.

6. Inform students to work in groups of two.

7. Instruct the groups to visit as many stations as possible, using the dichotomous k

organism to kingdom. Many specimens can also be classified out to phylum and cla

Needed:kingdoms dichotomous key for each student or group of students.

Dichotomous key assessmentfor each student The following shows example specimens that can be set out in this investiga

be collected by students for homework or obtained from teacher/department Specimens may range from living, dead, or preserved. If 3-D samples are no

images from magazines or the internet could be used.

I. Archaebacteria

Obtain images from the internet to displayII. Eubacteria

Set up a microscope with prepared slides of eubacteria Set up a microsope with a wet mount of yogurt to view bacteria cultures. A

search provides procedures for preparing a slide.

Obtain images from the internet to displayIII. Protists

Set up microscopes with slides of prepared protists Set up microscopes with slides or real protists (obtain elodea from the pet sto

sit for several days in water; the water will be full of protists).

Obtain images from the internet to displayIV. Fungi

Set out mushrooms collected by students or from the grocery store Set out shelf fungi collected by yourself or by students Set out yeast obtained from the grocery store Set out moldy food items

Directions:

I. Teaching Activity: Classifying Specimens of the Six Kingdoms

1. Set up your field notebooks, journals, etc. with the title, Using a Dichotomo2. With a partner, visit the stations in the room.3. Use the kingdoms dichotomous key to classify the specimen out to kingdom

out to phylum and class if the key allows this.4. Record the common name of the specimen on your paper as well as the spec

DIRECTIONS: Use the dichotomous key above to classify each of the following organisms into

the appropriate kingdom. Write the kingdom name on the line.

1. _______________ This rather soft, low-lying organism spends its day taking nutrients from a

rotten log through its hyphae. It continues to undergo cell division and grow larger.2. _______________ This organism spends its day roaming through the forest in search of food.

Its hunting techniques require use of its keen sense of smell and hearing.

3. _______________ This very small, thin organism spends its day using its flagellum to propel

itself through pond water. If sunlight is available, it can make its own food.4. _______________ This tiny organism spends its day reproducing rapidly (about once every 20

minutes), often inside the bodies of other organisms. Its genetic material is not contained inside a

nucleus.5. _______________ This organism spends its day in hot gases and molten rock deep within the

earth. This type of tiny organism existed billions of years ago.

6. _______________ This organism spends its day taking in carbon dioxide and releasingoxygen through its stomata. It never eats but can grow many meters tall.

7. _______________ This organism spends its day moving through water or soil by usingpseudopods which may surround food and take the food inside its cell membrane.8. _______________ This organism spends its day attached a hard underwater surface. Water

currents flowing through it provide the organism with food and oxygen and remove its wastes. It

has no organs, but some of its cells have specialized jobs.

BONUS: Besides classifying the kingdom, can you determine specifically what each organism

is? Write your answers in the spaces below. Be prepared to defend your answers. If you have

extra time, create an organism description of your own!
