ChemistryMeasures Up! MathScience Innovation Center
Matter surrounds us in the form of solids, liquids, and gases.
Atoms, Elements, and Molecules ATOMS-the basic building blocks of everything you see around you, even things you don’t see! ELEMENTS-the kinds of atoms we can have! MOLECULES-when atoms join together, forming bonds!
Changing which atom is bonded to which can change the properties of a molecule. C6H8O6 C6H8O6 Vitamin C Something Else 20 atoms: 6 carbon 8 hydrogen 6 oxygen It will change how it looks and acts.
What is a polymer? • Polymers are made of many many molecules all strung together to form really long chains. • Polymers can occur in nature or they can be man-made. This is a polymer. Many molecules are strung together. This is a small molecule. It is not a polymer.
What is a polymer? • These long polymer chains are formed by teeny tiny molecules called monomers. • A single polymer molecule is made out of hundreds of thousands (or even millions!) of monomers!
What kind of math is here? • Long chains mean adding the same thing over and over. • How does that relate to math? • Long chains can be hard to analyze. Sometimes it’s easier to look at the parts. • How does that relate to math?
Today we will… • Explore the construction of polymers. • Create a polymer. • Measure ingredients in a formula. • Convert decimals to fractions and fractions to percents. • Compare characteristics of polymers and non-polymers.
Ethane • First discovered in 1834 • A component of natural gas
Butane • Liquid form • Found in LPG bottles used in gas grills
Paraffin • Waxy solid • Used in candles and has a low melting point
Polyethylene • Solid • This is everyday plastic—milk jugs, detergent bottles, or any plastic
Chemical engineering uses math and the art of putting things together to create and discover new compounds.
