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.

I am a very firm believer that the world of physical science can be visualized and is an excellent medium for teaching students to model and to picture what happens at the molecular level. The first topic we decided to explore was balancing chemical equations. This seems like such a simple topic to chemistry teachers but I have found that it can be quite challenging for many of my inner city students. The first thing they ask me for is a list of rules that they can follow. We can discuss the problems of algorithmic teaching in a later post! For the time being let’s talk about how to get students to understand why they need to balance equations and discuss what we can call “Conservation of Atoms”.

For my students and me, the AP Chemistry exam does not mark the end of the school year. Once the AP exam is over, my students are exhausted but our class continues to meet for three more weeks. Each year we complete a qualitative analysis lab, but this year we finished earlier than I anticipated. For the first time all year, I have the luxury of time.

Each spring my Local Section of The American Chemical Society (ACS) hosts a rigorous two part exam as part of the selection process for the The International Chemistry Olympiad (IChO)  IChO is an annual int

Using a whiteboard or poster paper each group of students creates their interpretation of the model thus far based on a content unit they are given.

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.

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.

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!

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.

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.
