Hi, everybody. Good to see you today. We are going to talk about what sinks and what floats.
00:00:01
I have some cool objects, so make sure you pay attention, okay?
00:00:08
Here we are. I have two glass containers right here.
00:00:13
Two containers, and if you remember from earlier, glass is transparent, so you can see through it.
00:00:18
Can you see my fingers on the other side? They look funny, but glass is transparent, so you can see them.
00:00:25
So is water. So we're going to see what sinks and what floats.
00:00:31
First, let's look at a bottle cap. Do you think it'll sink or float?
00:00:36
Let's find out!
00:00:43
Look! The bottle cap floats on top of the water.
00:00:46
See? It floats on top of the water.
00:00:52
What about a rock? Do you think a rock will sink or float?
00:00:55
Let's check. Look, the rock sunk all the way to the bottom. See, the cap is on top and the rock
00:01:03
is all the way at the bottom. What about cotton? Do you think cotton will sink or float? Let's see.
00:01:16
Oh, look, cotton sinks once it gets wet. See, so the cotton sunk all the way to the very bottom.
00:01:29
So the rock sunk and the cotton sunk, but the plastic cap float. What about paper?
00:01:38
Do you think paper will sink or float? Let's see. Ah look, paper has floated on
00:01:47
the top. See paper is on the very top. What about a grape? Mmm I love grapes. Do
00:01:59
you think a grape will sink or float? Let's see. Look, the grape sunk. What about another
00:02:08
grape? It also sunk. As you see, the grapes are on the bottom and they sunk just like
00:02:18
the cotton sunk and the rock sunk. What about metal? What about this piece of metal? Metal
00:02:25
heavy, so do you think it'll sink or float? Let's find out. Ah, look, the piece of
00:02:33
metal right here also sunk to the bottom, just like the grapes sunk, the cotton
00:02:42
sunk, and the rock sunk. So what stayed on top? We have a bottle cap, another bottle
00:02:47
cap, and the piece of paper. That's all for today. Bye!
