All right, looks like you have an activity here where you're to make observations about this scenario here, and then come up with a problem with a possible solution, what is called a hypothesis.
00:21
And then we can test that hypothesis in a later time period.
00:27
So i started with some observations here.
00:29
I made three observations.
00:30
There's a large amount of debris floating in water here.
00:33
We know that.
00:36
We can't make a conclusion about where it's coming from, though.
00:40
It appears to be trash, though.
00:42
If we look at it, we can see that it's just discarded stuff.
00:45
It's not people's household materials that they would want to keep.
00:50
It's an old tire.
00:51
It's a lot of plastic jugs and other trash.
00:55
I'm not seeing anybody's, like, personal belonging.
00:59
So i'm not thinking this is from a flood.
01:03
This seems to be on purpose.
01:06
Somebody's throwing garbage away in the river.
01:10
And then this does look like it's a water supply that a river or a lake...
