00:11 Yeah . Today you need your student tax pages 89
00:15 your bookmarks and a half A cup of mixed dried
00:18 beans . Have you heard a whistle like this before
00:23 ? What's happening ? Well , my tea kettle is
00:26 hot . How do I know There's steam coming out
00:31 of the tea kettle ? And I know from my
00:33 experience of working in the kitchen , that steam is
00:37 hot . Water boiling on the stove makes steam ,
00:41 and if my hand gets too close to it ,
00:45 I can get burned . But now my water is
00:47 ready for tea and I'm ready to drink my tea
00:58 . And this leads us to a science process skill
01:01 that we're going to learn today . And that is
01:05 inferring . You're inferring what ? When you use what
01:10 you know , to tell why things happen now in
01:13 for is a new word , but it really isn't
01:15 a new idea . So how can we infer that
01:19 the tea kettle was hot ? Well , we see
01:22 that there was steam coming out of it . We
01:25 know that steam is hot , so we know that
01:27 the tea kettle is hot that you use what you
01:30 have already learned to infer that the tea kettle is
01:33 hot . Now in the last lesson , we were
01:35 talking about science process skills . Do you remember what
01:39 science process skills are ? Well , they are the
01:42 skills that scientists use to gather and use information .
01:48 So I want you to think about that as I
01:50 use this candy to do a little science . Now
01:54 I can separate this candy in a few different ways
01:59 . First of all , I can separate the candy
02:01 by color . I can put the red candy with
02:07 red here and the brown candy here and the orange
02:14 and yellow candy here . And I might have one
02:16 that doesn't quite fit , so I can separate by
02:18 color . I can separate by size and shape ,
02:24 so we have some longer , bigger pieces and some
02:27 medium sized pieces and some smaller pieces . I can
02:32 also separate the candy by shape . So I've got
02:37 round and I've got pointed and I've got long .
02:43 So I separated the candy by color and by size
02:50 and by shape . Separating things into groups is a
02:55 skill that scientists use , and today we're going to
02:57 learn what scientists call this science process skills . First
03:02 , let's read some words we have classify measure and
03:18 in for now I want you to say these words
03:22 with me . Read them with me . Classify ,
03:26 measure and in for I also want you to look
03:31 for these words . As you read , you're going
03:33 to be seeing them in darker , bold print .
03:35 They are vocabulary words that you will be learning .
03:39 Now , do you have your green and red bookmarks
03:42 ready to help you ? Each time you read ,
03:46 you can put the green bookmark at the first page
03:49 that you're going to read and then put the red
03:53 bookmark at the place where you need to stop as
03:57 you read . Look for the answer to this question
04:01 . What do you do when you classify ? Get
04:14 your handful of dried beans ready and I want you
04:17 to put them in front of you and then take
04:19 a few moments to separate the beans into groups according
04:22 to how they are alike . And I'm going to
04:25 do it , too , and I'm going to put
04:28 these in the same colour groups . So I'll put
04:31 my white together and my brown together and my sort
04:45 of spotted ones together take a few moments to do
04:51 it . But in this way we are grouping these
04:55 according to how they are alike by color . Yeah
05:06 , all right . How are years doing ? All
05:13 right ? I've got three separate color groups . So
05:20 when we are separating these according to how they are
05:24 the same by colorful by color , we are classifying
05:28 . So you classify when you group things and classifying
05:31 can help scientists understand things better . Let's look at
05:36 page eight in your book . How are these shells
05:40 grouped or classified ? While the same kinds of shells
05:46 have been grouped together , you can see that these
05:49 have been organized so that ones that are just alike
05:53 are grouped . We've got scallops , snails , starfish
05:58 and many others . What are some other ways that
06:02 these shells could be classified ? Well , they could
06:04 just be classified by color or just by size .
06:09 What if you wanted to classify a group of people
06:12 according to their eye color ? Well , you could
06:15 put people with brown eyes in one group and then
06:19 blue eyes in one group and green eyes in one
06:22 group . So we use that science process skill ,
06:26 classify when we group things . The second science process
06:31 skills you read about is measure . Why do we
06:35 measure things ? Well , we want to find out
06:38 how many , How big , how heavy , how
06:43 long , or how hot or cold something is .
06:47 So decide with me how we could measure something that
06:50 you could see at home , for example , with
06:53 jelly beans , we could count them to find out
06:56 how many . We could also weigh them to find
06:59 out how much a glass of water we could find
07:04 out . How much with a measuring cup ? Is
07:07 there another thing we could measure ? We could find
07:10 out its temperature to see whether it was hot or
07:12 cold or how hot or cold . How could we
07:16 measure a plant ? Well , we could weigh it
07:19 and find out how much , and we could measure
07:22 its height and find out how long and you'll be
07:26 doing some measuring activities soon . Besides , classify and
07:32 measure . You also read the word in for and
07:36 we've already talked about that , haven't we ? We
07:39 inferred that the kettle was hot . So what does
07:42 it mean to infer ? Well , you in for
07:45 when you use what you know to tell why ,
07:49 why things happen . Look at page nine and you
07:53 see the pot here . What color is the pot
07:56 ? It's red and what is coming from the top
07:59 of the pot . You see it steam . So
08:03 the color of the pot and that it has steam
08:06 are things that we know from looking at the picture
08:10 . What can you tell about the pot that is
08:12 not pictured ? Now I want you to put on
08:14 your thinking cap . Well , if this pot has
08:17 steam coming from it , it is hot . What
08:21 makes us think that it's hot , It has steamed
08:24 . So knowing that the pot is hot because it
08:27 is steaming is inferring So what does it mean to
08:31 infer ? Remember , when you use what you know
08:35 to tell why things happen , what is one of
08:38 the ways that you know that steaming pots are hot
08:42 ? You know this by now you've seen a pot
08:45 pot on the stove before . Maybe your mother has
08:48 cooked spaghetti noodles and you've seen that . I want
08:51 you to think about this example . If you look
08:53 outside and you see people wearing coats and hats and
08:57 gloves , what can you infer about the weather ?
09:02 Right ? It's cold outside . And even though you
09:05 may not be able to feel the weather , you
09:08 can infer that it's cold outside because you know that
09:11 people wear clothing like that when it is cold outside
09:16 . Have you ever seen a sign like this ?
09:20 Why do people put signs up like this ? Well
09:24 , they do it to keep us safe . Since
09:26 a wet floor is slippery , you can infer from
09:30 the sign that the floor may be slippery even though
09:35 that sign doesn't say that . Listen to this .
09:39 Sam did not do schoolwork today . He stayed in
09:42 bed all day . He had soup for lunch .
09:46 Why did Sam not do schoolwork today ? Why do
09:49 you think ? Well , he was sick . How
09:54 do you know ? I didn't tell you ? Well
09:57 , he didn't do schoolwork and he stayed in bed
10:00 . He even had soup . And when we're sick
10:03 , that's usually something that we like to eat .
10:06 Now , I didn't tell you that Sam was sick
10:08 , but you inferred it from what I told you
10:11 about what he did . Now it's time for quick
10:15 check . Why do we measure ? Think about it
10:21 . We measure to find out how much how many
10:26 . How heavy , How big , How long ,
10:29 How hot or how cold . In the next lesson
10:34 , we'll be learning about two more science process skills
10:38 . There's no assignment today .
