this was so helpful! the link my professor provided didn't contain an explanation for decantation but it's included in the activity questions. this video was exactly what i needed so thank you very much!
Why use the glass rod?........I mean, the glass rod is just in the way of the flowing water and makes it flow to other directions(outside the beaker).......Other than that it's a very helpful and great video for students
Well, nothing there is nothing technically wrong with your apresentation, a solid 10. But there are a few things you kinda slipped, like leaving a gap between the two points while folding the paper, what type of filter paper are you using, because the draining seems pretty slow. Also I had to do this.... Take a sip of beer every time he says "uh" or "um" XD
jairo sanchez no because there will always be source of error not 100% of the water was separated from the sand by specially decant and also in filtration there is source of errors
you need filter paper to filter out the larger substance which is called the residue while the substance that comes out of the funnel is i think the filtrate
