Hello again! Okay, now we have an experiment. For this experiment you need vinegar,
00:00:02
baking soda, a bottle, a funnel, and a balloon, okay? First you have to watch the explanation
00:00:13
and then you go to the chart with the scientist method. You fulfill the two first
00:00:28
questions, then you do the experiment and you fulfill the two next boxes, okay?
00:00:34
Let's start. We take the vinegar. The bottle is not very big, but the
00:00:42
main thing is the entrance must be small, okay? So we put the vinegar in, we leave it here, we take the
00:00:52
balloon, we use the funnel just to make it easy, easier, I mean, to put the bacon soda in, okay?
00:01:19
more or less two tablespoons. Now we have to connect the balloon with the bottle
00:01:31
but careful because the vacancy shouldn't go into the bottle yet okay so
00:02:01
just open it it's elastic so it's very easy and here it is what do you think is going to happen
00:02:08
when we go with the balloon up and the bacon so that gets into the bottle mixing with the
00:02:20
vinegar this is the first question okay and the last question after seeing everything
00:02:29
In the conclusions, please, after doing the experiment, try to explain if this change is physical or if it's chemical, a chemical change, and why.
00:02:39
See you later!
