Mr. Andersen explains the basics of balancing chemical equations. A visual guide shows you how to change coefficients to balance the atoms in reactants and products.

No prizes for guessing what Berkelium is named after. 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.

We've added some new footage to our video about beryllium, filmed at the MAX-lab synchrotron in Sweden. 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 the structure of a biomolecule fits the function of the biomolecule. For example and enzyme must interact correctly with a substrate to lower the activation energy, The covalent and non-covalent interactions are both important in shaping large molecules.

A new Bismuth video, including a better sample of Bimuth crystal and some information about its radioactivity. 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.

Students learn about various crystals, such as kidney stones, within the human body. They also learn about how crystals grow and ways to inhibit their growth. They also learn how researchers such as chemical engineers design drugs with the intent to inhibit crystal growth for medical treatment purposes and the factors they face when attempting to implement their designs. A day before presenting this lesson to students, conduct the associated activity, Rock Candy Your Body.

A new video about Bohrium, including footage from our trip to Darmstadt where the element was created and named. 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.

Raising or lowering the boiling or freezing point of a solution by adding solute.

In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond energy increases and the bond length decreases.

The video resource "Bonding Models and Lewis Structures: Crash Course Chemistry #24" 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.

Boron can be used to produce green flames. 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.

Students act as engineers to learn about the strengths of various epoxy-amine mixtures and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two chemicals in exacting ratios to fabricate the strongest and/or most flexible thermoset possible.

A new chapter in Introductory Organic Chemistry course. Lecture PowerPoint file and laboratory document are also included in this work. The goal of this chapter is to cover the basic ground of the food additives from the perspective of organic chemistry.

Lecture PowerPoint slides have all in-class questions/discussions and after-class assignments listed.

Laboratory document – Synthesis of Yellow 5 (Sunset yellow), an azo dye used in food industry. Document includes a short introduction, detailed experimental procedure and post-laboratory questions.

Bromine if one of the few elements which is liquid at room temperature and it's known for its "stench". 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.

We take a look at the famous buckyball, which is a molecule of 60 carbon atoms.
