Classifying Organisms

1. Classifying Organisms 6th Grade WebQuest • Introduction • Task • Process • Resources

2. Introduction Suppose you have only 10 minutes to run into a supermarket to get what you needed to make one of your very favorite meals. Could you do it? In most supermarkets this would be an easy task. Why? How would this task change if the items you were looking for were randomly placed around the store?

3. Introduction continued • Just like items are grouped in the grocery store, biologists have organized living things with similarities into groups so that the organisms are easier to study. • This process is called classification.

4. Task Working with a partner, you will: 1. learn how organisms are classified • understand how organisms are given a scientific name • research the distinguishing characteristics of the six kingdoms As you explore keep the following questions in mind:

5. Task, continued • Why do scientists classify? • What are the major levels of classification? • What is binomial nomenclature? • What are the six different kingdoms that are generally recognized by scientists today? • What are the characteristics and some examples of organisms from the six kingdoms?

6. Process • Carefully follow the directions for each section. • Answer all questions on the web quest guide and kingdom chart provided.

7. Why Do Scientists Classify? Classification– grouping/organizing things based on their similarities. Biologists use classification so that organisms are easier to study. Classification also shows relationships between organisms. The scientific study of how living things are classified is called taxonomy. On your web quest guide, define classification and explain why biologists classify.

8. Classify Organisms Based on Physical Features • How might you classify a sunflower, a robin, a lizard, a blue jay, a butterfly and a maple tree? Complete the table on your web guide.

9. Classify Organisms Based on Physical Features What characteristics may have been used to group these beetles? Write answers on your paper. 1. 2. 3. 4. 5. 6.

10. Levels of Classification Organisms are grouped by their shared characteristics. Based on this diagram, which level of classification is the most specific? Answer on your guide.

11. Understanding Classification Imagine a room filled with everybody from the state of Massachusetts. There may be some people from Westwood.There may be some people from your neighborhood.There may be some people that live on your street.You will be the only one that lives in your house. Massachusetts The most generalgroup you belong to is the state. The most specific group you belong to isthe house. The more levels you share with others, the more you have in common. Westwood Deerfield Conant St. #18

13. Binomial Nomenclature • Carl Linnaeus was a naturalist who devised a system of naming organisms. Linnaeus placed organisms in groups based on their observable features. Each organism has a unique, two-part scientific name. • Carl Linnaeus – 1707-1778

14. Scientific Name vs. Common Name • two-part name to each species - binomial nomenclature (e.g. Canis lupus, gray wolf) • The first name, the genus, covers a group of related species • The second name refers to a specieswithin a genus • Written in Latin, since it never changes • Common names can change from country to country

15. Scientific Names • How many things do you notice about the way the scientific name below is written? Record your answers on your guide. Bufoamericanus

16. Human Classification Using this diagram, what is the scientific name for human beings? • Homo sapiens • Which means wise man.

17. Kingdoms • Grouping organisms into kingdoms is based on several factors: • Presence or absence of a nucleus • What are the two vocabulary terms that apply here? Answer on your guide. • Made of one cell or made of many cells • What are the two vocabulary terms that apply here? Answer on your guide. • How organisms get their food. • What are the two vocabulary terms that apply here?Answer on your guide.

18. Kingdoms • Six different kingdoms of organisms are generally recognized by scientists today • Eubacteria • Archaea • Protists • Fungi • Plants • Animals

19. Kingdoms, continued Go to the following websites to find out the main characteristics of these kingdoms. Fill in the appropriate information on your Kingdoms chart. Feel free to use the textbooks provided or follow the additional links within the page as well. http://www.ric.edu/faculty/ptiskus/six_kingdoms/index.htm http://cbrannon.wiki.hoover.k12.al.us/file/view/Six+Kingdom+Classification+power+point1a!.pdf

20. Kingdoms, continued • Now that you have found some good information, follow the link below to hear a brief summary of the 6 Kingdoms • http://www.brainpop.com/science/diversityoflife/sixkingdoms/ Take the quiz too!

21. STOP • Please look over the web quest guide and the kingdoms chart. Did you fully complete them to the best of your ability? • If your answer is “NO”, then please move back through the web quest to answer all the questions. • If your answer is “YES”, you may continue and explore some of the characteristics of animal and plant phyla.
