0:06i am dr romari i'm going to help you
0:10with experiment
0:112
0:12demonstration part 1 of the experiment
0:15two we have some elements in a closed
0:17jar and i'm holding for you to record
0:20your observation when you're recording
0:23observation you want to see what color
0:25it is is it going to be shiny is not
0:28going to be shiny and is it liquid solid
0:32at at room temperature and if you read
0:35the introduction or not if when you read
0:38the introduction for experiment two
0:41about physical property you have better
0:44idea what information you want to
0:47collect you can pause the video at any
0:49time you like
0:50to to focus on one element and record
0:55your observation for these elements so
0:57we are looking at the element of carbon
1:00then we are looking at the elements of
1:03copper copper you have seen copper at
1:06home for copper like piping for plumbing
1:09the copper is used or sometimes for
1:12cookware it is
1:14it is used the same thing for carbon
1:16it's the the pencil lead it's carbon so
1:20you can you also have them tom iodine is
1:24uh
1:25is in closed container i'm not going to
1:27open it because of all these signs that
1:30you recognize them they are not safe for
1:32us to even open it
1:34so it's solid it's brown color solid i
1:38have to tell you that
1:41then next we have magnesium i want you
1:43to check the magnesium and record your
1:47observation for
1:48for magnesium we have
1:51magnesium these are smaller pieces of
1:53the magnesium we also have the magnesium
1:57ribbon
1:58that magnesium driven in a different
2:00container just had to grab to show it to
2:03you
2:04these are the pieces of magnesium
2:08ribbon some metals you can touch all the
2:10cookwares or any metal that you see
2:13at home
2:14you can touch them they are not all
2:17dangerous but some elements that they
2:19are toxic you don't want to
2:22next element is
2:24silica
2:25so we have the powder of the
2:28silica record your observation
2:31and that is silica
2:34next we have sulfur
2:37record your observation for
2:39our sulfur
2:40based on the physical property based on
2:42the appearance color and how it looks
2:46next we have
2:49zinc
2:50we have pieces of zinc we've seen zinc
2:53before in experiment one this is
2:55experiment two we are using zinc for
2:58classification of the compound based on
3:00metal non-metal and also some general
3:03properties for the for the elements
3:08so these are the the the few elements
3:11that you will be classifying
3:14[Music]
3:19you
