1 00:00:00,750 --> 00:00:09,189 All right class, let's move forward on page 99 and let's begin with activity four. 2 00:00:10,730 --> 00:00:18,550 You will listen as I describe each of these simple machines and number. 3 00:00:18,550 --> 00:00:23,320 Let's begin with number one. 4 00:00:23,320 --> 00:00:36,420 one you screw on the cap of a water bottle so here is the cap and here is the water bottle 5 00:00:36,420 --> 00:00:41,619 and we screw this on to close the water bottle 6 00:00:41,619 --> 00:00:57,469 number two you turn the axle around the wheel so find the picture of the wheel and axle and 7 00:00:57,469 --> 00:01:14,640 please number it two once again two wheel and axle number three push down the lever to lift 8 00:01:14,640 --> 00:01:26,680 up the box. Which picture shows the lever? Please number lever with number three. 9 00:01:26,680 --> 00:01:36,200 All right, let's continue on to exercise five. Complete the sentences with names 10 00:01:36,200 --> 00:01:43,640 of simple machines. So I will speak the full sentence and you will write out 11 00:01:43,640 --> 00:01:55,200 out the missing word in each one, the missing machine, with its correct purpose and description. 12 00:01:55,200 --> 00:02:16,800 Let's begin. We use a pulley to lift objects. We use a wedge to cut objects. We use a lever 13 00:02:16,800 --> 00:02:20,580 to push objects up or down. 14 00:02:22,120 --> 00:02:25,560 So please write in the correct simple machine 15 00:02:26,979 --> 00:02:31,780 with its purpose and function as a machine. 16 00:02:31,780 --> 00:02:33,520 Okay, great work. 17 00:02:33,520 --> 00:02:38,520 And now let's continue forward with these fun pictures 18 00:02:38,539 --> 00:02:43,539 where we will get to draw in which simple machine is needed 19 00:02:43,539 --> 00:02:50,539 for the person to move, or to cut, or to lift. 20 00:02:50,539 --> 00:02:56,539 So first, we have a picture of a woman in a car. 21 00:02:56,539 --> 00:03:09,039 Which tool or machine do we need at the bottom of the car to move the car forward and backward? 22 00:03:09,039 --> 00:03:14,830 Tell me which machine is needed. 23 00:03:14,830 --> 00:03:16,830 Yes, excellent. 24 00:03:16,830 --> 00:03:23,830 We need a wheel and axle to roll and move the car forward. 25 00:03:23,830 --> 00:03:31,270 So you can draw in the circular wheels. 26 00:03:31,270 --> 00:03:34,270 Okay. 27 00:03:34,270 --> 00:03:41,270 And write the tool, the machine, wheel and axle. 28 00:03:41,270 --> 00:03:48,270 Next, here is a man who needs to cut a sandwich for lunch. 29 00:03:48,270 --> 00:04:02,259 What tool does he need to cut the sandwich? Does he need a knife or a spoon? Yes, excellent. 30 00:04:03,039 --> 00:04:16,959 The man uses a knife to cut the sandwich. So here I have my knife. He will use to cut the sandwich. 31 00:04:16,959 --> 00:04:30,860 and tell me what kind of machine is a knife. If we use that machine to cut, excellent. It is a wedge. 32 00:04:30,860 --> 00:04:43,389 So please write wedge. Finally, we have a man who needs to load and put the boxes into 33 00:04:43,389 --> 00:04:56,939 the moving van or the truck. So please draw in which simple machine he needs to help him 34 00:04:56,939 --> 00:05:16,060 use a ramp to move the heavy boxes forward and up into the truck. Yes, excellent. We will draw 35 00:05:16,060 --> 00:05:25,100 an inclined plane so that the man can push the boxes up into the truck. One 36 00:05:25,100 --> 00:05:35,339 more time, we will write wheel and axle, wedge, and inclined plane below each of 37 00:05:35,339 --> 00:05:42,980 our drawings that we have done. Finally, let's read this box together. Some simple 38 00:05:42,980 --> 00:05:50,120 machines are called tools. Tools and machines help people every day at home, 39 00:05:50,120 --> 00:06:01,240 work, and school. So an example of a tool would be our knife which is a wedge. Okay 40 00:06:01,240 --> 00:06:05,959 thank you for learning with me and completing your work.
