2 Grouping- Plants And Animals

3 Students will be able to:1) give reasons why it's useful to group things 2) observe objects eg. (leaves, plants, rocks) and classify them in a number of different ways giving reasons for each grouping 3) record the criterion used for a given grouping 4) draw a concept map of matter 5) list the criteria for classifying living and non-living things 6) list the criteria for classifying plants and animals 7) observe in school yard and classify them in a number of different ways 8) draw a concept map linking the main concepts in classification of matter 9) identify ways for caring for living and non-living things in the school environment

4 Activities:1) Give 3 reasons why it is useful to group things. Examples: Libraries Books by subjects Books by authors Fiction or non-fiction Magazines and Journals Supermarkets Canned items Cold items Cereals eg. Grains + cornflakes Pastries Spices

5 Reasons to group things: Easier to find things Easy to identify Prevents chaos and confusion Saves time 3) Construct the conept map of MATTER. (see page of text).

7 List the features that enable us to distinguish between a stone and an ant. Recall the seven characteristics of life. The acronym MRS GREN can be used to recall same, that is: M- ovement R- espiration S- ensitivity G- rowth R- eproduction E- excretion N- utrition

8 The table below can be used to aid comparison between plants and animals. ANIMALS Can locomote Have legs and segments Have heads Have mouthparts Eat PLANTS Do not locomote Green in color (most) Contain leaves, stem, root Do not eat Make own food

11 Grouping- Plants And Animals

12 Students will be able to:1) Review previous objectives covered i.e characteristics of living things 2) Identify a variety of plants that bear flowers and fruits as well as non-flowering plants. 3) Divide flowering plants and non-flowering plants into sub-groups 4) Classify animals into vertebrates and invertebrates 5) Describe sub-groups of vertebrates and invertebrates 6) State the differences between plants and animals 7) State the features of the five groups of vertebrates 8) State the features of invertebrates 9) Describe the most important features of an insect 10) Describe the main features of mammals and name some examples of different types of mammals

18 Assignment:- Research and find out the name of an egglaying mammal and which mammal is termed 'marsupial'

19 ANIMALS INVERTEBRATES VERTEBRATES BIRDS AMPHIBIANS REPTILES FISHES MAMMALS

20 Characteristics of Vertebrates: Cold-blooded and without scales- amphibians Cold-blooded but have scales covering their bodiesreptiles Cold-blooded whose skin is covered by scales and have fins- fish Warm-blooded and have bodies covered by feathersbirds Warm-blooded and have bodies covered by furmammals

21 KEY FOR CLASSIFYING VERTEBRATES Is the animal warm-blooded? YES Does the animal have hair/fur? YES Mammals NO Birds NO Is the body covered by scales? YES NO Does the animal have fins? YES Fishes Amphibians NO Reptiles

22 Features of invertebrates in relation to vertebrates. No backbone Some have exoskeletons Soft- bodied Cold- blooded

23 KEY FOR CLASSIFYING INVERTEBRATES Body divided into segments arranged one after another NO Hard spiny body with 5 parts arranged in a star pattern Echinoderms- e.g starfish, sea urchins YES Soft slimy body may Be enclosed in a shell Molluscs- e.g Snails, slugs, clams Hollow sac-like body opening surrounded by tentacles Cnidarians (coelentrates) - e.g jellyfish, sea anemone Body with paired Jointed legs Soft body with no true legs Annelids- e.g Earthworms, leeches Two pairs of Antenna on head Crustaceans- e.g Crab, shrimp Arthropods4 pairs of legs Arachnids(2 body parts) eg. spiders Insects(3 body parts) eg. Flies, butterflies

24 Exercise: The following questions can be used as a guide to classify invertebratesdoes it have a soft or hard body? Is its body divided into segments? Does it have a shell or spines? Does it have legs and if so, how many? How many pairs of 'feelers' or antennae does it have on its head? Exercise: Do an analysis of differences among the arthropod group using # of legs, # of segments, # of wings etc.

25 Insects: Are divided into 3 sections; head, thorax and abdomen The thorax and abdomen are divided into segments It has 2 pairs of wings (although sometimes the rear pair are very small) It has 3 pairs of legs, attached to the thorax It has a single pair of antennae, attached to the head. It has a pair of large eyes, called compound eyes (each eye contains many lenses)

26 Summary of Content Female mammals can produce milk in mammary glands and suckle their young Mammals are able to regulate their body temperature. Have a coat of hair which helps to reduce heat loss. Limbs with 5 digits on the end (exceptions in horse and pig, these are reduced) Strong jaws and well-developed teeth Usually highly active with good senses of smell, hearing and sight Most mammals give birth to live young EXCEPTIONS TO MAMMALS Unusual mammals- Duck-billed platypus, echidna (found in Australia and New Guinea lay eggs) Kangaroos and wallabies of the Americas are examples of pouched animals or marsupials.

27 Other mammals are called placental mammals MAIN GROUPS OF MAMMALS Toothless Insectivores Hoofed mammals Rodents Carnivores Marine mammals Primates Bats are the only flying mammals

28 QUESTIONS 1) Explain why spiders and scorpions are not insects. Find out which group they belong to 2) What is the difference between a placental mammal and a marsupial? 3) Some mammals do not show all the usual features. Name 2 unusual mammals and say what is different about them. 4) What is an insectivore? 5) Imagine that you run a zoo or wildlife park. What mammals would you include? Explain your choices.
