All right.
00:04
The question is asking about conducting an activity to know the process of curdling of milk using the scientific method.
00:11
So i'm going to give an example that you could follow.
00:15
So first of all, for observation, you know, an observation you could start with would be that certain substances cause milk to curdle.
00:24
As far as a question goes, that you can seek to answer with your investigation.
00:28
It could be something like what kinds of substance cause milk to curdle.
00:34
As far as a prediction goes, or a hypothesis, substances containing citric acid cause milk to curdle, so that could be a possible hypothesis.
00:44
As far as your experimental plan goes, the materials you would need would be milk, you know, five empty cups, things like lemon juice, lime juice, orange juice, perhaps a salt solution and a sugar solution.
00:58
And as far as a very simple procedure you could follow, step one would be to pour equal amounts of milk into five separate.
