  1. Classifying Organisms

  2. Classification and Taxonomy • Classification is the process of grouping things based on their similarities. (What they have in common or the same) • Taxonomy is the scientific study of how living things are classified. This is useful because once they are grouped scientists know a lot about the organism based on their group.

  3. Linnaeus • Carl Linnaeus developed a naming system for all living things in 1753. It is still being used today!

  4. Binomial nomenclature • Binomial nomenclature is the formal system of naming living things. • It was created so there would be no confusion when talking about an organism.

  5. Raise your handif you know what these birds are called.

  6. Commonly called the Robin • However, one is the European Robin and the other is the American Robin. • So when scientists talk about “the robin” …they may get confused as to which one they are talking about. • European robin = Erithacusrubecula • American robin = Turdusmigratorius

  7. How it looks • The scientific name is always: • Two word name • In italics • First letter of the first word is CAPITAL • First letter of the second word is lower case • First word is the genus name • Second word is the species name (specific epithet)

  8. Let’s Practice • Grey squirrel • Genus: sciurus • Species: carolinensis • How to write it? • Sciuruscarolinensis

  9. Let’s Practice • Striped skunk • Species: mephitis • Genus: mephitis • How to write it? • Mephitis mephitis

  10. Let’s Practice • Mallard • Species: platyrhynchos • Genus: anas • How to write it? • Anasplatyrhynchos

  11. YOUR JOB! • You will need to choose a living thing (that you can draw) • You will be making a mini-poster of your organism, showing the common AND scientific name.

  12. YOUR JOB! • You will be completing the following: • Drawing a picture of your living organism • Writing the common name (what we call it) • Writing the scientific name (CORRECTLY) • This will need to be colored and done neatly!

  13. Your job! • As homework: • Please come to class tomorrow with what you have chosen!! • Write it down in your purple direction sheet so you don’t forget. • This needs to be a very specific organism…it can’t be a frog, • what type of frog?
