1 00:00:00,750 --> 00:00:18,870 Hello class. Today we will continue in our natural science book on page 106 and we will learn all about the difference between inventions and discoveries. Let's get started. 2 00:00:18,870 --> 00:00:29,870 Discoveries are things that we find. Inventions are things that we make that didn't exist before. 3 00:00:29,870 --> 00:00:42,869 Petroleum, a potato, and fingerprints are discoveries. A wheel, a microscope, and a mop are inventions. 4 00:00:42,869 --> 00:00:52,869 Let's look at these two pictures and define discoveries or inventions. 5 00:00:52,869 --> 00:01:02,869 Okay, so here in this first image we have a computer, a bicycle, and a mobile phone. 6 00:01:02,869 --> 00:01:11,049 We know that two of these require electricity, and all of these are 7 00:01:11,049 --> 00:01:21,049 machines that have many parts. So this picture shows you three different 8 00:01:21,049 --> 00:01:30,829 inventions, so I want you to please write I for the inventions, okay? In the next 9 00:01:30,829 --> 00:01:45,790 image we have rice, fire, and tomatoes. We have two types of food that we harvest in fields 10 00:01:45,790 --> 00:01:55,390 with agriculture and we have fire which is a natural element. All three of these pictures show 11 00:01:55,390 --> 00:02:03,629 discoveries. Discoveries are things that humans find out in nature and use to eat 12 00:02:04,189 --> 00:02:16,219 or to help them with life. So please write D for discoveries. Next we will look and classify each 13 00:02:16,219 --> 00:02:31,169 picture with its object name under a discovery or invention. A wheel spins around and helps move 14 00:02:31,169 --> 00:02:42,289 objects. So you will have a wheel on something such as a car or a bicycle or a scooter. A wheel 15 00:02:42,289 --> 00:02:57,340 is an invention. Next we have petroleum. Petroleum is an oil and we dig this oil out from the ground. 16 00:02:58,139 --> 00:03:09,539 So petroleum exists from nature so it is a discovery. Next think of a microscope. 17 00:03:09,539 --> 00:03:18,759 A microscope is a machine made of many different parts. Scientists use 18 00:03:18,759 --> 00:03:27,560 microscopes to help them look very closely at small objects. You can use a 19 00:03:27,560 --> 00:03:34,439 microscope for any kind of other invention that you need. So we will put 20 00:03:34,439 --> 00:03:39,319 microscope for inventions. 21 00:03:39,400 --> 00:03:46,439 Next think of potatoes which are a food, fingerprints 22 00:03:46,439 --> 00:03:54,919 which are a body part, and mop which has two parts 23 00:03:54,919 --> 00:04:00,840 and is a machine that we use to clean. It's a tool we use to clean the 24 00:04:00,840 --> 00:04:08,800 house. So use these last three, potatoes, fingerprints, and mop, and think, is it a 25 00:04:08,800 --> 00:04:18,720 discovery or invention? And please write each under its correct box. Let's now 26 00:04:18,720 --> 00:04:27,120 continue with exercise three. Complete with words from activity two, then read 27 00:04:27,120 --> 00:04:35,939 out loud. I have helped you fill in the first sentence so that you can complete 28 00:04:35,939 --> 00:04:45,259 the second on your own. I have used the pictures as I wrote them in under 29 00:04:45,259 --> 00:04:53,879 discoveries and filled in one, two, and three different discoveries to finish 30 00:04:53,879 --> 00:05:02,040 the sentence. So here I have potatoes, petroleum, and fingerprints are discoveries because they 31 00:05:02,040 --> 00:05:12,879 already existed. Now I want you to use the remaining three, that is the three that are left 32 00:05:13,839 --> 00:05:24,800 on your inventions side of the diagram chart and please fill in three different inventions 33 00:05:24,800 --> 00:05:37,709 that you can see above. For example, a wheel is an invention so I will write wheel and two more 34 00:05:37,709 --> 00:05:46,709 are inventions because someone made them. So someone created these using
