Today we will be working on our new unit, Unit 5, and the topic is matter and materials. 2 00:00:14,539 --> 00:00:30,339 So these are all different objects and a material is something that we use, humans use to make things and help us with our lives. 3 00:00:30,500 --> 00:00:44,079 okay so let's begin and turn to page 78 in your natural science book natural materials come from 4 00:00:44,079 --> 00:00:55,719 plants animals or the ground we find them in nature these materials can be made by humans 5 00:00:55,719 --> 00:01:03,719 Cotton, wood, wool, and stone are natural materials. 6 00:01:03,719 --> 00:01:13,719 Cotton and wood come from plants, wool comes from an animal, and stone comes from the ground. 7 00:01:13,719 --> 00:01:22,719 So natural materials can be found in mountains, in the soil. 8 00:01:22,719 --> 00:01:41,420 It can be found from animals, such as sheep, or llama, or pig, or many other animals, or the ground, which will be soil, such as where plants grow. 9 00:01:42,640 --> 00:01:45,500 So let's begin with activity one. 10 00:01:46,480 --> 00:01:50,219 Listen, stick, and write the materials. 11 00:01:50,219 --> 00:01:57,159 so you will listen to me and please because we do not have stickers please 12 00:01:57,159 --> 00:02:08,759 copy what I have drawn for each space in each box so first we have cotton draw 13 00:02:08,759 --> 00:02:17,219 the cotton and write please in calligraphy cotton next we have wood 14 00:02:17,219 --> 00:02:28,280 Please draw a rectangle to draw wood that comes from trees. Next we have wool. 15 00:02:28,280 --> 00:02:37,180 Please draw the picture of wool and write in very neat handwriting. And 16 00:02:37,180 --> 00:02:45,939 finally stone. Here is a picture of a stone that you may use as an example for 17 00:02:45,939 --> 00:02:52,300 you're drawing. Now I have some examples here to show you. So first let's start 18 00:02:52,300 --> 00:03:01,139 with stone. Here I have a crystal and a crystal is very similar to a stone. We 19 00:03:01,139 --> 00:03:09,819 dig them out from the ground and they come in many different shapes and colors 20 00:03:09,819 --> 00:03:21,379 and sizes. Here is an example of stone. Here I have cotton. This is a ball of 21 00:03:21,379 --> 00:03:39,379 cotton. Next, wool. Here is a wool scarf. It is very soft. And finally, wood. My table 22 00:03:39,379 --> 00:03:50,860 here is made out of wood. Now let's go to activity two where you will circle in either green for 23 00:03:50,860 --> 00:04:01,639 natural material or red for man-made material. So something, an object that is made by humans. 24 00:04:02,520 --> 00:04:13,319 So we have first a picture of cotton. Do you think cotton is natural for green or man-made red? 25 00:04:13,960 --> 00:04:24,839 What do you think? We learned that cotton is natural, so circle green. Next here is wool. 26 00:04:24,839 --> 00:04:36,540 is wool natural or man-made? Here we have a cup of a cup for drinking and a cup is 27 00:04:36,540 --> 00:04:46,620 made out of glass. Humans make cups to drink out of. So is this man-made or 28 00:04:46,620 --> 00:05:01,019 natural please circle here we have wood and rock or stone stone and rock are the 29 00:05:01,019 --> 00:05:14,310 same so please circle stone in red or green whatever you think and a marker so 30 00:05:14,310 --> 00:05:29,350 one more time. Cotton, wool, glass, wood, stone, marker. Please circle natural or man-made. 31 00:05:31,110 --> 00:05:42,949 Finally, match the natural material to where it comes from. Stone comes from the ground. 32 00:05:44,310 --> 00:05:47,069 Wood comes from a tree.
