00:00:00,500 --> 00:00:04,500
Let's continue on page 98.

2
00:00:04,500 --> 00:00:12,150
We use machines every day at home and in the classroom.

3
00:00:12,150 --> 00:00:18,149
Machines make work easier and they can help us move objects.

4
00:00:18,149 --> 00:00:23,149
Machines can help us lift, push, and pull things.

5
00:00:23,149 --> 00:00:28,149
Simple machines have one or two parts.

6
00:00:28,149 --> 00:00:35,189
A wheel and axle, a leveler, a pulley, a wedge, a screw,

7
00:00:35,189 --> 00:00:40,149
and an incline plane are all simple machines.

8
00:00:40,149 --> 00:00:44,229
Now, because we do not have stickers, you will listen

9
00:00:44,229 --> 00:00:50,899
and we will draw together each of these simple machines.

10
00:00:50,899 --> 00:01:03,380
Number one, a wheel and axle. So here we have the wheel and then the pull is the axle.

11
00:01:08,629 --> 00:01:24,310
Number two, a wedge. Here we have a type of wedge. This is a axe and an axe is a type of wedge.

12
00:01:24,310 --> 00:02:11,750
Number three, screw. Number four, a lever. Number five, a pulley. Number six, an inclined plane.

13
00:02:11,750 --> 00:02:26,580
If you need to, you can pause your screen right here and copy each picture. Now,

14
00:02:26,580 --> 00:02:35,169
let's continue to activity number two. Look at activity one and number the words.

15
00:02:35,169 --> 00:02:44,770
So you will look and listen as I say each simple machine and write the correct number.

16
00:02:44,770 --> 00:03:07,879
One, wheel and axle. Two, wedge. Three, screw. Four, lever. Five, pulley. Six,

17
00:03:07,879 --> 00:03:23,439
inclined plane. Now let's continue to activity three. You will use the pictures above and the

18
00:03:23,439 --> 00:03:35,840
numbered vocabulary and we will write in under each picture which simple machine it is. I will

19
00:03:35,840 --> 00:03:43,099
tell you the first one for an example and then you can use your own work to fill in the other

20
00:03:43,099 --> 00:03:50,979
other four. This first picture is a lever. A lever is used to

21
00:03:50,979 --> 00:04:00,620
push an object up and down. Next we have wheel and axle. So look

22
00:04:00,620 --> 00:04:09,280
at the pictures and try to think which is a wheel and axle. A

23
00:04:09,280 --> 00:04:17,680
wheel and axle moves heavy objects by making them roll forward on a round wheel.

24
00:04:19,839 --> 00:04:28,879
Next we have a pulley. A pulley is a simple machine used to pull or move an object up,

25
00:04:29,680 --> 00:04:32,720
so it lifts objects up in the air.

26
00:04:35,120 --> 00:04:47,920
Inclined plane. An inclined plane is a ramp and we can use this ramp or slope to move heavy objects

27
00:04:47,920 --> 00:04:57,920
forward and up. We use inclined planes to load a truck or a car with heavy materials and boxes.

28
00:04:57,920 --> 00:05:07,680
and wedge. A wedge is used to push two objects apart or to cut an object in

29
00:05:07,680 --> 00:05:19,339
pieces. Some examples of wedge machines are scissors or axes and they are used

30
00:05:19,339 --> 00:05:26,680
to cut. So please write under each picture which is which simple machine.

31
00:05:26,680 --> 00:05:29,040
Okay, good work.
