ChemCrafter, from the Science History Institute (formerly the Chemical Heritage Foundation), is a free iPad app that mimics a classic chemistry set. It is set up as a game, with three sections: reactions with water, reactions with acid, and salts. The app shows the progress of the reaction (smoke, color change, etc.) when two elements are mixed in a reaction vessel, and also gives the change in enthalpy of the reaction.
This is a flipped classroom module that covers the concept of dynamic equilibrium, and how dynamic equlibrium plays a role in the anticancer mechanism of the therapeutic cisplatin.This activity is designed to be done at the end of the typical second quarter/second semester general chemistry equilibrium unit. Students will be expected to have learned the following concepts prior to completing this activity:
This is an in-class case study activity that introduces relevancy between atomic structure (specifically isotopes) and animal migration. Students will apply their knowledge of isotopes, writing atomic symbols, and calculating average atomic mass while also connecting this information to another application (in this case animal migration).
This is a flipped classroom module that covers the concepts of time-integrated rate laws. This activity is designed to be done at the end of the typical second quarter/second semester general chemistry kinetics unit. Students will be expected to have learned the following concepts prior to completing this activity:
This in class activity consists of two demonstrations to be performed by the instructor, followed by a worksheet that students may work on independently or in groups. The demonstrations allow the students to determine when a reaction has occured, when it has not occured, and generate qualitative reaction energy profiles to match these observations. This activity is designed to take place during a description of kinetics in general chemistry. Detailed descriptions of the procedure and activity may be found in the "Overview for Instructor."
This activity is designed to be done in the middle of the typical first quarter/first semester general chemistry electronic structure unit. Students will be expected to have learned the following concepts prior to completing this activity:
a) how the four quantum numbers are determined (principal quantum number, angular momentum quantum number, magnetic quantum number, and electron spin quantum number);
b) the basic concept of electron spin, and how atomic orbitals that possess two electrons will result in the spin-paring of electrons;
This is a flipped classroom activity intended for use in a first semester general chemistry course.
This is an activity designed to introduce general chemistry students to reading the chemistry literature by familiarizing them with the structure of a published article. The activity first presents an article from the Whitesides group at Harvard about writing a scientific manuscript, along with a video about the peer-review process. There are two parts to the questions in the activity, which are based on a specific article from Nature Communications (doi.org/10.1038/s41467-019-08824-8).
In this in-class activity, each student calculates the inital pH, equivalence volume, and pH at the equivalence point for both a strong acid-strong base and a weak acid-strong base titration.
In addition, each student is assigned a unique volume before the equivalence point and a unique volume after the equivalence point for each titration curve.
The data from the class is then assembled in Excel to construct the two titration curves.
