This PowerPoint is one small part of the Taxonomy and Classification unit from www.sciencepowerpoint.com. A 3800+ slide Five Part PowerPoint presentation becomes the roadmap for an amazing and interactive science experience full of built-in lab activities, built-in quizzes, video links, class notes(red slides),review games, projects, unit notes, answer keys, and much more. Also included is a student version of the unit that is much like the teachers but missing the answer keys, quizzes, PowerPoint review games, hidden box challenges, owl, and surprises meant for the classroom. This is a great resource to distribute to your students and support professionals. The Classification and Taxonomy Unit covers topics associated with Taxonomy and Classification. The unit examines all of the Kingdoms of Life in detail. Areas of Focus within The Taxonomy and Classification Unit: -Taxonomy, Classification, Need for Taxonomy vs. Common Names, What is a Species?, Dichotomous Keys, What does Classification Use?, The Domains of Life, Kingdoms of Life,The 8 Taxonomic Ranks, Humans Taxonomic Classification, Kingdom Monera, Prokaryotic Cells, Types of Eubacteria, Bacteria Classification, Gram Staining,Bacterial Food Borne Illnesses, Penicillin and Antiseptic, Oral Hygiene and Plaque, Bacterial Reproduction (Binary Fission), Asexual Reproduction, Positives and Negatives of Bacteria, Protista, Plant-like Protists, Animal-like Protists, Fungi-like Protists, Animalia, Characteristics of Animalia, Animal Symmetry, Phylums of Animalia (Extensive), Classes of Chordata, Mammals, Subclasses of Mammals, Characteristics of Mammals, Fungi, Positives and Negatives of Fungi, Divisions of Fungi (Extensive), Parts of a Mushroom, 3 Roles of Fungi, Fungi Reproduction, Mold Prevention, Plant Divisions, Kingdom Plantae. If you have any questions please feel free to contact me. Thanks again and best wishes. Sincerely, Ryan Murphy www.sciencepowerpoint@gmail.com
