Next we will talk about solid, liquids and gases and make a CO2 balloon from an acid and base. Which group does a polymer belong to? Polymers are long skinny molecules that can be tangled to create plastics, nylon, and more. Naturally they are found in our hair, wood, and spider silk. The students will tangle some of these.
Our project is to make a lip balm. We will find the melting point of shea butter and beeswax and make an emulsion of the 2 liquids after they melt. An emulsion is a mixture of two or more liquids that are normally immiscible
(un-blendable). Emulsions are part of a more general class of two-phase systems
of matter called colloids We'll add an emollient, almond oil, that keeps moisture from evaporating from the skin. The kids get to add their own fragrances to engineer there own special type.
