1 00:00:00,180 --> 00:00:10,939 Let's continue on page 102. We will continue learning about a new type of machine called 2 00:00:10,939 --> 00:00:19,399 complex machines. Let's begin by reading the box above. Simple machines can work together 3 00:00:19,399 --> 00:00:28,699 to make more complex machines. Complex machines have more than two parts, so it has three, four, 4 00:00:28,699 --> 00:00:36,579 five, a hundred, just more than two parts. They are combinations of simple machines. 5 00:00:37,979 --> 00:00:47,060 Complex machines make difficult or dangerous tasks easier, so they make life easier and more safe 6 00:00:47,060 --> 00:00:56,619 for humans. They do things that people can't. A computer, a car, and a washing machine are 7 00:00:56,619 --> 00:01:05,099 complex machines. So these machines have very specific and special functions and abilities 8 00:01:05,099 --> 00:01:15,519 that help humans live life easy, clean, move, pick up, and do things every day with a little bit 9 00:01:15,519 --> 00:01:24,700 more ease. Number one. In exercise one, I will describe each of these machines and you will 10 00:01:24,700 --> 00:01:32,140 listen and then match. You probably recognize most of these complex machines from your home, 11 00:01:32,859 --> 00:01:41,099 so as I say you can look at the pictures and match to the correct word. Computer. 12 00:01:43,180 --> 00:01:56,230 I browse the internet on the computer. Car. I drive to school in the car. Radio. 13 00:01:56,230 --> 00:02:00,450 I listen to news on the radio. 14 00:02:01,950 --> 00:02:02,909 Television. 15 00:02:04,150 --> 00:02:07,670 I watch my favorite movie on the television. 16 00:02:09,210 --> 00:02:10,129 Camera. 17 00:02:11,330 --> 00:02:16,090 I take a picture of my family with the camera. 18 00:02:17,449 --> 00:02:18,849 Washing machine. 19 00:02:19,729 --> 00:02:23,770 I wash my dirty clothes in the washing machine. 20 00:02:23,770 --> 00:02:34,770 So please match, for example, computer, and do the same with all of the rest of these complex machines. 21 00:02:36,069 --> 00:02:42,150 Alright, and when you are finished with exercise one, let's move forward to exercise two. 22 00:02:42,729 --> 00:02:45,689 Alright, let's continue now with exercise two. 23 00:02:46,770 --> 00:02:51,949 We will color the simple machines red and the complex machines blue. 24 00:02:51,949 --> 00:02:58,949 Please grab a red and blue pencil or marker and let's begin. 25 00:02:58,949 --> 00:03:10,949 Remember that simple machines are levers, wedge, pulley, inclined plane, wheel and axle. 26 00:03:10,949 --> 00:03:15,949 Simple machines only have one or two parts. 27 00:03:15,949 --> 00:03:23,729 Complex machines are machines such as electronics or other more complex 28 00:03:23,729 --> 00:03:31,990 machines that can do more. You will see, for example, I have colored the wedge red 29 00:03:31,990 --> 00:03:40,930 because a wedge is a simple machine. Now please go through to the other machines. 30 00:03:40,930 --> 00:03:57,289 we have a calculator, a microwave, a screw, a mobile phone, a shovel, a axe, and a 31 00:03:57,289 --> 00:04:05,710 clock. And please color as you think red for simple machine or blue for complex 32 00:04:05,710 --> 00:04:14,830 machine. Let's move forward with exercise three. Match, then read the sentences. So 33 00:04:14,830 --> 00:04:20,769 you will match the beginning of each sentence on this side to the correct end 34 00:04:20,769 --> 00:04:28,709 of the sentence. Each of these sentences will describe what we use a certain 35 00:04:28,709 --> 00:04:34,629 machine for. So what we use a car for, what we use a telephone for, and what we 36 00:04:34,629 --> 00:04:43,389 use a washing machine for. Please match the beginning to the end of each 37 00:04:43,389 --> 00:04:52,220 sentence correctly. Now listen and I will go over and tell you the correct 38 00:04:52,220 --> 00:05:05,209 matching. We use a car to go from one place to another. We use a telephone to 39 00:05:05,209 --> 00:05:17,029 communicate with people. And we use a washing machine to wash clothes. Okay, 40 00:05:17,029 --> 00:05:23,870 good work. Let's continue on to page 103.
