I think there is a chemical that is in the soap and when we add water and scrub it the chemical from the soap spreads out because the soap is probably heavier than water.
Chemistry is all about different types of stuff -or substances,to use a scientific word. It's all about what substances are,what they can do,what's inside them and how they change.

What I think about chemistry and my inquiry: I started to look into chemistry be cause my inquiry was about soap and I thought soap is similar to chemicals and potions which are chemistry.
I thought of this question because being a scientific thinker needs to observe things even though it is really simple.So one night I was taking a bath then I washing my hair,then I washed the shampoo of but I saw that there was soap and foam so I started to make predictions and theories.
My results were that bubbles are created by soap because the soap is a kind of chemical that doesn't harm us but does lots of things.I also Think that (but I am not so sure about this one) the water takes away the weight in the soap and when we rub it with force it spreads out and turns into bubbles.
