Polymers are a vital part of our everyday lives and nearly all consumer products have a plastic component of some variation. Students explore the basic characteristics of polymers through the introduction of two polymer categories: thermoplastics and thermosets. During teacher demos, students observe the unique behaviors of thermoplastics. The fundamentals of thermoset polymers are discussed, preparing them to conduct the associated activity in which they create their own thermoset materials and mechanically test them. At the conclusion of this lesson-activity pair, students understand the basics of thermoplastics and thermosets, which may entice their interest in polymer engineering.

Check out some samples of cobalt, and learn about its role in colour televisions. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Rob Stockman explains why Coke and Pepsi will be changing their recipes in the US.

Students investigate the property dependence between concentrations and boiling point. In section 1, students first investigate the boiling point of various liquid solutions. In section 2, they analyze data collected by the entire class to generate two boiling point curves, one for salt solutions and one for sugar solutions. Finally, in section 3, students use the data they have analyzed to determine how to create a solution that has a particular boiling point and is a cost-effective design.

Professor Poliakoff overcomes his fear of tall ladders to observe the chemistry of concrete.

In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The mass of an anylate can be determined through both gravimetric analysis and a titration.

In this video Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms (including chemical, mechanical, light, electrical, and thermal). In AP Chemistry students must be accountable for interactions involving an increase in volume over time.

There has been debate about whether the periodic table's newest element should have the symbol Cp or Cn? This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Here's a new video about copper, including a nice demonstration and some stories from The Professor. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because of differences in charge.

In this video Paul Andersen explains how covalent bonds form between atoms that are sharing electrons. Atoms that have the same electronegativity create nonpolar covalent bonds. The bond energy and bond length can be determined by graphing the potential energy versus the distance between atoms. Atoms that share electrons unequally form nonpolar covalent bonds.

In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four valence electrons and can create three-dimensional shapes.

The Professor demonstrates the reactivity of Chromium Trioxide and the department smoke alarms!

Students create silver nanoparticles using a chemical process; however, since these particles are not observable to the naked eye, they use empirical evidence and reasoning to discover them. Students first look for evidence of a chemical reaction by mixing various solutions and observing any reactions that may occur. Students discover that copper and tannic acids from tea reduce silver nitrate, which in turn form silver. They complete the reaction, allow the water to evaporate, and observe the silver nanoparticles they created in plastic dishes using a stereo microscope. Students iterate on their initial process and test to see if they can improve the manufacturing process of silver nanoparticles.

The video resource "The Creation of Chemistry - The Fundamental Laws: Crash Course Chemistry #3" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
