We have known that soap is used to wash off oil and grease. It is able to do that thanks to the soap's structure of a non polar tail and a polar head. The tail is non polar and oil is non polar so the tail is able to interact with oil. The head is polar due to unequally distributed electrons, which has the ability to interact with water, which is also polar. Water and oil don't mix because water is polar while oil is non polar, "like dissolves like". Thanks to soap, the oil is formed spherically by the soap structures' tails. Their heads are connected with water so that water and oil are dissolved in a solution. By that, we are able to wash the oil off. In the video, after Meena ate the chocolate, she went to the bathroom to wash her hands with soap and get rid of the grease on her fingers.

Elements and Compound -Ai Vy
Element
is a substance that can not be broken down to any smaller substance of
itself. Compound is a combination of two or more elements. In the video,
elements and compounds were represented by Snicker bars. Meena hold on
Snicker bar and it was an element; Ai Vy hold a few of them together to
represent a compound. In chemistry, for example, we have Hydrogen(H) and
Oxygen(O) as elements. If we have H2O, a combination of 2 Hydrogens and
one Oxygen, we have a water compound.
