1 00:00:01,179 --> 00:00:10,140 Hello everyone! Today we're starting a new unit in natural science. It is called 2 00:00:10,140 --> 00:00:20,859 materials. What are materials? Materials are the things we use to make other 3 00:00:20,859 --> 00:00:38,750 things. Very clear, right? Okay, I'll show you. This is a book, right? A book is made of paper, 4 00:00:38,750 --> 00:00:52,789 okay? You see, this material is paper. What else is made of paper? Okay, a notebook. A 5 00:00:52,789 --> 00:01:16,680 A notebook is made out of paper, like this one, you see? The book is made of paper. Now, what about this? This is a napkin, okay? It's used to clean your mouth after you eat. 6 00:01:16,680 --> 00:01:51,200 It's made of paper as well. Okay. Now, another material. Here we've got a fork. Okay. This is a fork. And this fork is made of metal. Okay. Metal is the second material we use to make things. Okay. 7 00:01:51,260 --> 00:02:21,520 This box, for example. See it? It's also made of metal. Alright. Another fork. What is this fork doing here? This is not a very good fork. 8 00:02:21,520 --> 00:02:40,599 Okay, it is a plastic fork. Okay, sometimes we use it when we go to eat outside, in a camping, and so on and so forth. This is not very good for the environment. Okay, not good. 9 00:02:40,599 --> 00:02:56,939 But plastic is very common to make things. Okay, for example, a plastic bottle, okay, like this one, or another plastic bottle. 10 00:02:56,939 --> 00:03:15,379 We can also find a ruler made of plastic. And even a pen is made out of plastic. Okay? Good. 11 00:03:15,379 --> 00:03:29,120 Now, we've seen plastic, metal, and paper. 12 00:03:29,939 --> 00:03:34,319 Okay, now let's turn into another material. 13 00:03:36,300 --> 00:03:44,780 What does this, which is a pencil, and this have in common? 14 00:03:44,780 --> 00:03:58,280 They are made out of wood. Wood comes from the tree, right? This is wood, and this is wood, okay? 15 00:03:58,280 --> 00:04:13,479 This is wood to make pencils, to make chairs, to make desks, to make tables, to make shelves in your room, to put your books in, etc. 16 00:04:13,479 --> 00:04:25,480 Now, another type of material. This material is cold and very fragile. You can break it very easily. 17 00:04:25,480 --> 00:04:39,680 glass okay glass is another type of material to make glass right or bottles 18 00:04:39,680 --> 00:04:49,689 like a bottle of water or a bottle of wine for parents the last type of 19 00:04:49,689 --> 00:05:11,850 material is very soft and nice and comfy it is fabric like this t-shirt fabric makes clothes 20 00:05:11,850 --> 00:05:25,750 tape, in t-shirts, or in pillows to sleep, or in cushions, okay? Very nice and soft. 21 00:05:26,709 --> 00:05:35,290 Okay, let's see if we remember the six types of materials that we have seen today, okay? 22 00:05:35,290 --> 00:06:14,959 Okay? Plastic, metal, wood, paper, glass, and fabric. Okay? Do you like my teacher? I love it too. Okay. Thank you very much for watching. Now do the exercises. Bye bye.
