Shyla nos explica el tema matter
Now let's move forward to exercise three.
00:00:00
We will look at each picture and write S
00:00:04
for solid such as ice or snow,
00:00:08
L for liquid with water, and
00:00:13
G for gas, the gas form of a liquid.
00:00:18
So let's move forward. Here we have a glass of water.
00:00:23
A glass of water is something that we can drink and the water can get other
00:00:27
materials wet. So we will write L for liquid water. Here we have a picture of
00:00:35
snow. Snow is a type of weather and it happens when water freezes into a solid.
00:00:46
so snow is going to be S for a solid form of water. Next, we have a picture of the clouds
00:00:57
that we see up in the sky. Do you think that clouds are liquid or gas? What do you think?
00:01:10
Yes, excellent. Clouds are water in gas form because the water evaporates,
00:01:21
meaning it rises up into the sky and forms clouds out of many drops of water.
00:01:33
So we will write G. Next we have a picture of a snowman. What do you think?
00:01:40
is this solid, liquid, or gas? Please write the correct letter S, L, or G. Let's go on to
00:01:49
exercise four. Here we have many different pictures and you will tick the
00:01:59
things you can bend, meaning you can use your hands to change the shape, then
00:02:07
complete the sentences below. I can or can't bend. First we have a plastic
00:02:13
ruler. Plastic is a flexible material so you should tick here because you can
00:02:21
bend plastic. Now we have a tomato. A tomato is a soft food. Because it is soft
00:02:31
it is flexible so you can bend. Next we have a comb. A comb is made out of a hard
00:02:41
material either hard plastic or hard wood so you should not tick. Do not tick
00:02:52
for comb. Next we have a wooden spoon. Wood is a hard and rigid material so we
00:03:00
cannot bend a wooden spoon. Next, we have a sponge. We use a
00:03:10
sponge to clean our house. We need it to be able to bend to
00:03:19
clean. So yes, you can bend so you should tick sponge. And
00:03:25
finally, we have a football. footballs are made out of hard
00:03:32
plastic and they need to keep their shape so that we can use them to play. So do not tick because you
00:03:38
cannot bend a football. Now complete the sentences. I can bend with the objects that you put a tick
00:03:46
and I can't bend you will fill in with the objects that you did not tick such
00:03:59
as wooden spoon I can't bend a wooden spoon there are things we can bend
00:04:09
there are things we can twist there are things we can squash when you let them
00:04:17
go some things return to their shape so they go back to how they looked originally. The more you
00:04:23
push or pull some things the more they bend but some can also break. Look at each picture. I will
00:04:32
explain to you what stretch, twist, or squash means and then you will fill in under the picture
00:04:45
which is which. First, we have the word stretch. Stretch means to pull on a material and it makes
00:04:52
it longer. So it makes the material much longer when you stretch a material. Next, we have the
00:05:04
word twist. Twist is to bend and turn a material to change its shape. So you sort of twist
00:05:15
like this motion to bend and turn the material. Finally, we have squash. Squash is to press
00:05:27
on a material and make it flat like a piece of paper. So squash you
