Activities

ChemEd X activities are student-centered resources intended to aid learning chemistry topics.

ChemEd X emphasizes inquiry-based activities where students pose questions (with direction from the teacher) and then attempt to discover the answers through scientific inquiry.

Sodium carbonate reacts with hydrochloric acid producing bubbles

Students combine sodium carbonate and hydrochloric acid generating carbon dioxide gas which is allowed to escape. They measure the actual yield of carbon dioxide produced (missing mass), calculate the theoretical yield using stoichiometry, and then the percent yield. Students understand that 100% yield is the most appropriate answer (based on the Law of Conservation of Mass), so after considering the meaning of significant figures and the uncertainty of their measurements they are asked to decide if they did (or did not) get an answer that might indicate the validity of the Law.

Although many students have been exposed to the concept of density before reaching my Chemistry class, I always start the year with this POGIL-like activity.

A quick google search will allow you to find many laboratory activities for making ice cream in chemistry class. Some of the links provide questions to incorporate into the activity. I have used several over the years and will share my modified version here.

An independent study on the chemistry topic of coordination compounds and complex ions suitable for AP Chemistry and first-year college chemistry students is presented. This student activity accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions" and is suitable for use by the student to guide their activity.

This laboratory exercise accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions". The laboratory serves as part of an extended exercise on the chemistry topic of coordination compounds and complex ions. The entire lesson as described in the article also exposes students to how chemical research is conducted and the conflicts and uncertainties that lead to new theories and discoveries.

I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.

Orbital Viewer, written by David Manthey, is a fantastic program for displaying electronic orbitals.  You can read more about the program here.  I have my students use Orbital Viewer when learning about quantum numbers and their associated rules, electronic orbitals, and other quantum concepts.  I have developed a worksheet that allow

This is a series of experiments, PhET Interactive Simulation activities, and clicker questions to relate macroscopic and molecular representations of homogenenous solutions. Graphing skills are also used.

This activity is used as a reinforcement activity following my use of JCE Classroom Activity #113: An Interlocking Building Block Activity in Writing Formulas of Ionic Compounds. It could be used as a stand alone activity to support writing ionic formulas and names.
