In this 15-minute video lesson a stoichiometry problem with a limiting reagent is examined!

This 14-minute video lesson looks at suspensions, colloids and solutions. And the difference between molarity and molality.

This 15-minute video explains how you can look at valence electrons to figure out reactivity.

This 30-minute video lesson looks at Van Der Waals Forces: London dispersion forces, dipole attractions, and hydrogen bonds.

This 16-minute video lecture demonstrates a vapor pressure example using the Ideal Gas Law.

This 10-minute video lesson looks at the equivalence point when titrating a weak acid.

Young parents, Max and Andrea Forest, learn that their child is suffering from the genetic disorder, thalassemia. Treatment requires a lifetime commitment to whole blood transfusion and chelation therapy, both of which must be administered on a daily to weekly basis. Students read the case, answer a series of questions, and then decide how they would treat the child if they were the parents. The case was developed to introduce students to the role of metal ions and coordination chemistry in biological systems. It would be appropriate for use in courses in biochemistry, molecular biology, bioinorganic chemistry, and bioethics, among others.

This case study was developed to engage students by making connections between core concepts in organic chemistry and the health-promoting chemical, curcumin, found in turmeric. The case is in the form of a dialogue between a couple about the surprising color change observed in their turmeric-containing soup when baking soda is added. Concepts taught by the case include keto-enol tautomerization, resonance theory, chelation, and pH dependant hydrolysis and ionization. Developed for a first-semester organic chemistry course, the case could be adapted for use in undergraduate biochemistry and food science courses.

This 18-minue video shows how to calculate the pH of a weak acid.

This 13-minute video lesson examines the pH of .2 M of NH3 (weak base).

This 15-minute video lesson examines how to calculate the pH or pOH of strong acids and bases.

This 15-minute video lesson examines the pKa and pKb relationship between conjugate acids and bases (both of which are weak).

Matching game, including matching common ionic charges and ions and the compounds they form and naming of greek prefixes for covalent molecules.

This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.

This lesson has students solving the mystery of a note by conducting chromatography. They will test different washable markers and see that different marker colors are made up of various pigments. They will compare and contrast the note chromatography with other chromatography results from a variety of markers.

This is a laboratory investigation where students will use the scientific method to solve a new, experimental question in chromatography.
