Problem

Investigate the method of classification used by scientists today.

Hypothesis

If we classify a group of random objects, then we can individualize each object.

A. Phylum Writing is School objects involved in writing, phylum Non-writing is school objects not used in writing.

Path for Wool Strand: Non-School- Easily Flexible- Non-Rubber

D. All items in the same class are in the same phylum, all items in the same phylum are in the same kingdom.

Conclusion

Scientists classify objects for 3 reasons. First, it shows relationships among organisms by grouping them together. Second, they use the genus and the species as the name for the organism. Third, the classification system is the same worldwide. We separated the objects from kingdoms, to phylum, then to class. Our kingdoms were the School and Non-School groups. If we were to add a cork and a nail, they would botch go to the Non-School kingdom.

Classify:

Kingdom: Animal

Phylum:FliesSwimsStays Stationary

Class: Stingers No Stingers Pointed Round Star Shaped

Head Head

Each class does not necessarily have to have the same number of organisms or have the same number of classes for each phylum.

1. Student A separated this by environment, air or sea.

2. Student B separated this by eyes or no eyes.

3. All animals in the same phylum do not belong in the same class.

4. A. This group has backbones.

B. Can live in land and water.

5. Classes are more specific than kingdoms.
