=**Lesson 3**=



Lesson Three's topic is ‘Classification: Clarifying Concepts’
 *  Part 3 of the 3-part program in Classification.
 * Learning Area: Science: Life & Living : Structure & Function : Classification
 * Year 8’s.
 * This class is an hour and a half morning class, late in the week.

**Outcomes** __WA Syllabus:__ [|ea_ss_sci_ll(DETK102077b) (2).pdf]


 * 1) Organisms have characteristics (structure and function) that can be used to classify them.
 * 2) As an organism is classified from kingdom level to class level, it is grouped with other organisms that are increasingly similar.


 * Lesson Three Objectives**
 *  Differentiate between different groups using Online Activity set.
 *  Explain what kinds of characteristics are/can be used to classify organisms at Kingdom, phylum, and class level. That is, identify some characteristics which differentiate between organisms.
 *  Decide/Evaluate what kingdom, phylum and class a variety of nominated organisms should belong to when given sufficient information about their structure and function.
 *  Understand Classification to a higher degree than in part 2 of this 3-part program on classification.


 *  Prior Knowledge:** Students will be expected to have an adequate grasp of the content and concepts in lessons one and two.

 *  Resources Required:**
 * Capacity for Teacher’s computer to be projected at front of class.
 * Students need to have own computer with internet access for online activity
 * Quiz/test handouts.


 * Lesson Steps**
 * 1)** 9.05 am: Collect homework.

 *  2)** 9.08 am: Video at beginning - Sir David Attenborough :


 *  3)** 9.15 am: Explain to students that we want students to have an appreciation of classification AND the interconnectedness of all things! Talk about The further steps of classification and how it is possible to see even more precisely how closely different organisms are related as you move down the levels of classification. But we are only going so far as class. Use some of the classes of chordates – mammalia, amphibia, aves, reptilia, osteichthyes as examples. Describe some features which define them.

 * <span style="font-family: 新細明體;"> 5)** 9. 35 am: Activity 2: Practice with whole class. Give example of an animal. First of all, it consumes food via photosynthesis. What kingdom could it belong to? (Could belong to more than one.) ask class: what question could you ask to find out what kingdom it belongs in: (is it multicellular/unicellular). It is in plantae. Then ask for suggestions – what features could you ask about the further classify it – characteristics pertainign to structure and function!


 * <span style="font-family: 新細明體;"> 6)** 9.45 am: Activity 3: Students construct a poster - on the computer of the information they now know about classification.


 * <span style="font-family: 新細明體;"> 7)** 10.40: Finish up.


 * <span style="font-family: 新細明體;"> 8)** 10.45 am: Set homework: After school, go home and think about how all the animals and plants and mushrooms and organisms you can’t even see are interrelated, and how they all evolved from a single-celled organism! Amazing! And have a good weekend!
