1 00:00:00,430 --> 00:00:07,710 Hello boys and girls, how are you today? I'm fine, thank you. Today we are going to review 2 00:00:07,710 --> 00:00:16,109 the new natural science unit called Living Organisms. In this video we will review Lessons 1 3 00:00:16,109 --> 00:00:23,070 and 2, but first of all let's talk about the different goals included in this unit. 4 00:00:23,070 --> 00:00:33,070 them. Goal number one is to distinguish between living things and non-living things. Goal number 5 00:00:33,070 --> 00:00:45,890 two is to learn about sales and levels of organization. Goal number three is to make 6 00:00:45,890 --> 00:00:57,229 a sale model and presentation and goal number four is to classify living things into five kingdoms 7 00:00:57,229 --> 00:01:06,650 are you ready let's move on to unit sorry lesson number one lesson number one is called 8 00:01:06,650 --> 00:01:15,090 living things and your own lives remember that there are different groups in which we can 9 00:01:15,090 --> 00:01:28,609 classify living things. Last year we learned about animals and plants. This year we will learn three 10 00:01:28,609 --> 00:01:39,329 new groups. On the other hand, known living things can be classified into natural and artificial. 11 00:01:39,329 --> 00:01:58,200 Now, let's talk about living things. No matter if they are mammals, vertebrates, invertebrates, or plants, all living things need to follow the life cycle. 12 00:01:58,200 --> 00:02:11,919 Mirror world, living things are born, grow, reproduce, and die. 13 00:02:14,840 --> 00:02:16,039 Very good job. 14 00:02:16,740 --> 00:02:19,360 Now we can move on to the following slide. 15 00:02:20,080 --> 00:02:22,699 The three vital functions. 16 00:02:22,699 --> 00:02:32,699 Every single living thing needs to perform three vital functions, and these are the following ones. 17 00:02:32,699 --> 00:02:44,699 Mirror world, nutrition, reproduction, and interaction. 18 00:02:44,699 --> 00:02:49,460 Very good job! 19 00:02:49,460 --> 00:02:56,460 Let's analyze these functions one by one. 20 00:02:56,460 --> 00:03:01,039 Function number one, nutrition. 21 00:03:01,039 --> 00:03:08,159 Living things need food to grow and for energy. 22 00:03:08,159 --> 00:03:22,439 Mirror world, living things need food to grow and for energy. 23 00:03:22,539 --> 00:03:28,400 Remember that animals feed on other living things. 24 00:03:28,400 --> 00:03:36,199 Mirror world. Animals feed on other living things. 25 00:03:36,199 --> 00:03:44,710 Remember, depending on their food, we can classify animals into 26 00:03:44,710 --> 00:04:04,580 omnivores herbivores and omnivores on the other hand plants use sunlight to make their own food 27 00:04:04,580 --> 00:04:25,519 We roll over. Plants use sunlight to make food. Very good job. We can now move on to the following vital function, in this case, reproduction. 28 00:04:25,519 --> 00:04:30,519 All living things reproduce. 29 00:04:30,519 --> 00:04:42,160 Some animals give birth to babies, while other animals lay eggs in the middle of the world. 30 00:04:42,160 --> 00:04:48,529 All living things reproduce. 31 00:04:48,529 --> 00:04:53,529 Some animals give birth to babies, 32 00:04:53,529 --> 00:05:00,290 Other animals lay eggs very well down. 33 00:05:00,290 --> 00:05:12,120 In addition, remember that plants reproduce through seeds or spores. 34 00:05:12,120 --> 00:05:14,120 New word. 35 00:05:14,120 --> 00:05:25,120 Plants reproduce through seeds or spores. 36 00:05:26,000 --> 00:05:32,399 good job let's move on to the last of the three vital functions 37 00:05:33,120 --> 00:05:39,040 hero world vital function number three interaction 38 00:05:42,639 --> 00:05:53,839 animals interact with the environment and other living things for example this picture the dog 39 00:05:53,839 --> 00:06:03,600 is interacting with this little girl and her mother. On the other picture we can see an eagle 40 00:06:03,600 --> 00:06:16,720 trying to catch a little rat. This rat is also interacting. She's running very fast trying to 41 00:06:16,720 --> 00:06:31,800 escape from the ego plants do also interact they cannot move but they respond to stimuli 42 00:06:33,639 --> 00:06:43,079 okay so remember there are three people functions your work nutrition 43 00:06:43,079 --> 00:06:50,000 reproduction, reproduction and interaction.
