Our World • • • • • Everything on earth can be grouped as: LIVING NON-LIVING Living things can be put into 2 groups: PLANTS AND ANIMALS Living Things • For something to be classified as living it MUST obey the 7 characteristics of life! • They are…………………….. 1. Growth • All living things grow • As we get older we grow taller • All the animals and plants can grow • Non-Living Things e.g. A book – can’t grow 2. Nutrition • All living things need food this process is called NUTRITION • Most Green Plants make their own food from sunlight in a process called PHOTOSYNTHESIS 2. Nutrition • All animals must eat food to get their energy • Carnivores – eat only other animals • Herbivores – eat only plants • Omnivores – Eat both animals and plants 3. Respiration • Plants and Animals need oxygen gas to release energy from food in a process called RESPIRATION • Animals get their oxygen by breathing in and out 3. Respiration • Plants get the necessary gases by let it pass in and out of its LEAVES 4. Movement • All living things can move • kangaroos jump, fish swim, birds fly • Flowers open in the daylight and close at night 5. Reproduction • All living things have the ability to produce a new young generation • Mammals produce babies • Fish lay eggs • Tall Oak Trees grow from acorns • Apple trees grow from apple pips 6. Response • All living things can respond to changes in the environment • If you are scared a common RESPONSE is to cry • Plants RESPOND to sunlight by making their branches grow towards it 7. Excretion • Excretion means getting rid of poisonous waste substances from inside a living thing • Animals breathe out to excrete poisonous Carbon Dioxide • We sweat to remove excess salt and water 7. Excretion • Plants excrete their waste substances through tiny little holes in their leaves RECAP TIME…… • What 2 groups can all objects be divided into? • LIVING AND NON-LIVING • All living things must obey the following 7 characteristics….. • Growth, Nutrition, Respiration, Movement, Reproduction, Response, Excretion • An animal that eats other animals is called? RECAP TIME ….. • • • • • • A carnivore An animal that eats only plants is called? A Herbivore An animal that eats both is called? An Omnivore All living things can be divided into 2 categories….. • PLANTS AND ANIMALS Classifying Animals • We can further classify animals into 2 main groups • Vertebrates and Invertebrates Vertebrates • Vertebrates are animals which have a backbone • From this backbone all the other bones are supported • The name comes from the bones of the spine called the VERTEBRAE Invertebrates • Invertebrates are animals which have no backbone • In fact they have no bones at all! For U 2 DO …… • • • • • • • Vertebrates 1. 2. 3. 4. 5. Copy this table into your copy and complete with examples • • • • • • Invertebrates 1. 2. 3. 4. 5.
