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.

This is my first year of using Modeling Instruction in my chemistry classes. During a fit of productivity, I created some bell ringers for unit one, which is partly about conservation of mass. I hope you will find them useful. Comments are welcome. I would love to see what others might be using.

What Not To Do Lab
by Doug Ragan
Wed, 08/26/2015 - 09:26

During the first week of school, I welcome my students to the What Not To Do Lab. The PDF is available for free at the Laboratory Safety Institute website. I use the cartoon activity to review their Safety Contract handout from the night before (I use the one from FLINN Scientific). With more than 30 safety violations shown, the cartoon serves as a great ice breaker as I have each student introduce themselves and then list a safety infraction being shown on the cartoon.

Building Molar Mass, molar mass calculations, mole calculations

An advantage to teaching on the trimester schedule allows me the opportunity to teach the same course again roughly twelve weeks later. So after grading my 2nd trimester students’ Chemistry B final exams, I was able to evaluate certain topics that caused my students problems, reflect on my teaching, and then determine how I was going to better prepare my students in the 3rd trimester chemistry B class.

In a recent post, I indicated that I would make available the Chemical Reactions lab that I modified to meet NGSS guidelines. Enjoy!

Writing Conversion Factors Preview
Sat, 11/15/2014 - 23:01

This worksheet is intended to be used as a "Guided Instructional Activity" (GIA). Students read a statement that gives a either a conversion factor or a pair of related measures and then write the information as two equivalent fractions ("conversion factors") and as an equality.

Initial framework for use with stoichiometry GIAs
Sat, 11/08/2014 - 21:40

This set of three worksheets are intended to be used as collaborative "Guided Instructional Activities" (GIAs). Two students cooperate to complete the steps of a stoichiometry problem, alternately doing parts of the process as they explain what they are doing and evaluate their partner's work.

Mole Conversion Guided Instructional Activity Preview
Fri, 11/07/2014 - 23:37

The three "Guided Instructional Activities" in this activity are three cooperative learning pieces in which students are guided through the process of converting from one unit to moles (or moles to a unit) by the method of "unit analysis" (dimensional analysis). Students alternate steps in the process and evaluate the success of each step.

This worksheet asks students to do basic conversions of mass or molecules to moles and vice versa. The worksheet requires students to complete their work in a particular format and to inlcude number, unit, and chemical identity for each item in the "given," in each conversion factor, and in the answer.
