Science SCI.III.2.2 Strand: Using Scientific Knowledge in Life Science - Organization of Living Things Standard: Benchmark: Grade: 1 All students will use classification systems to describe groups of living things. Compare and contrast (K-2) familiar organisms on the basis of observable physical characteristics. (This Unit will cover animals only. Another Unit in the 1st grade science curriculum will cover plants.) Constructing & Reflecting: SCI.I.1.1 - Generate reasonable questions about the world based on observation. SCI.I.1.2 - Develop solutions to problems through reasoning, observation, and investigation. SCI.I.1.3 - Manipulate simple devices that aid observation and data collection. SCI.I.1.5 - Develop strategies and skills for information gathering and problem solving. SCI.I.1.6 - Construct charts and graphs and prepare summaries of observations. SCI.II.1.4 - Develop an awareness of and sensitivity to the natural world. Vocabulary / Key Concept Context Words describing animal parts: Animals that look similar: • snakes • worms • millipedes • • • • • • backbone skin shell limbs feathers scales Animal Kingdom Characteristics, ie • mammals: fur • birds: feathers • fish: scales Resources Knowledge and Skills Benchmark Clarification: Coloma Resources: Animals may have similar and/or different features. Animals may be put into groups based on similarities and differences. Newbridge Early Science Program “big books” and teaching guides: -Squirrels All Year Long (vertebrates) -Busy As a Bee (invertebrates) -A Butterfly is Born (invertebrates) -The World of Ants (invertebrates) K-2 groups will: • Compare and contrast body coverings (feathers on a robin, scales on a trout) Newbridge Discovery Links “little” readers with reproducible Home/School Connections blackline masters: -Ants (invertebrates) -Fly, Butterfly (invertebrates) -How Do Frogs Grow? (invertebrates) -Animals Hide (vertebrates) Various animal cards from Science Poster Series Animal Kingdom Posters and teacher’s guide Community Resources: Sarett Nature Center Curious Kids Museum Other Resources: • Webliography. http://mtn.merit.edu/mcf/SCI.III.2.E.2.html Instruction Benchmark Question: How are groups of living things classified? Focus Question: How can observable characteristics help us classify animals? Animals can be sorted by their observable body parts. Students will categorize an animal according to its characteristics and how the characteristics work. Assessment Optional Assessment Informal: Post the six animal characteristics (backbone, skin, shell, limbs, feathers, and scales) (See Key Concepts). Have students brainstorm a list of animals for each of the six categories. Examples: • Insulation: fur, feathers, blubber • Support: exoskeleton (outer), endoskeleton (inner) • Food-Getting: claws, beaks, teeth • Protection: quills, horns, claws, eyes • Movement: legs, wings, fins, webbed feet Students will: • Categorize an animal according to its characteristics and how those characteristics work • Categorize vertebrates — animals with a backbone • Categorize invertebrates — animals without a backbone Teachers Comments Use classification systems to describe groups of living things. With the help of the big yellow bird or the purple dinosaur, children at an early age sort "which one doesn't belong." There is a tremendous diversity of life forms. With over 1,500,000 identified organisms, biologists need some way of organizing these life forms so they can be studied. Students informally observe a wide variety of living things in and out of school. Just like scientists, they note similarities and differences in their observations. At the elementary level, students focus on observable characteristics. These informal categories will be challenged with the acquisition of additional knowledge of anatomical differences, in particular those characteristics that are not observable.
