AP Chemistry Post-Exam Activity: Coordination Compounds & Complex Ions

coordination compounds and complex ions

I published an article about an independent study unit I use with my AP Chemistry class two years ago, A guided group inquiry lesson on coordination compounds and complex ions. In the time since it was published, I have expanded the unit quite a bit and written some new assignments to go along with it. I use this unit every year as a post AP activity and am very fond of it. I thought some of my readers might enjoy seeing how it has changed and get access to the new assignments I have developed for it.

Topics featured in this issue include: visualizations for chemistry teaching and learning, periodic table resources for teaching visually impaired students, biochemistry in the classroom and laboratory, spectroscopy in the laboratory, commentaries on analytical chemistry topics, resources for teaching, distilling the archives: guided-inquiry experiments.

Bell Ringers for Conservation of Mass

bell ringer 1

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.

You can access the bell ringers below. They are part of the "student document".

 

 

Time required: 

Approximately 5 minutes per class period.

Energizer Lab

Students proceed through a prior knowledge activity, practice creating and using a voltaic cell and use of a model designed to simulate the particulate level activity within a voltaic cell. The teacher checks for student understanding at specific points as groups work together. A discussion follows to help clarify ideas.

Time required: 

About one 60 minute class period for lab and manipulative procedure.

Trend Setter Lab

Trendsetter Lab

Students will proceed through a pre-lab engagement activity, organize element cards based on similarities & trends, discuss trends with the class and then produce a periodic table that includes the trends discussed within the lab. The teacher will check for student understanding at specific points as groups work together.

Time required: 

Two 60 minute class periods for procedure. You may wish to include more time for discussion. The assessment portion can be done as homework.

Periodic Table Project

Periodic Table of Legos

Students choose a topic and select items to incorporate into a periodic talbe. Students explore trends related to their own topic and relate to the trends on the actual Periodic Table of Elements.

Time required: 

I provide my students 1 and 1/2 weeks to complete this project. Most students do not need this much time. I provide the extra time for those students who do not have adquate internet/computer access.
