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.
Have you seen the new Crayola Crystal Effects Window Markers? You can draw on windows with these markers. Better yet, you can use these markers to teach students some chemistry! After drawing on a window with these markers and waiting a little while, the marker ink appears to crystalize! Check out the video.
Have you ever cooked a marshmallow in a microwave? In case you are not familiar with this experiment, when a marshmallow is heated in a microwave, gases trapped in the marshmallow expand and escape. When the gas molecules escape from the marshmallow, they push against the marshmallow, causing it to expand. Check out the video.
Allow me to introduce myself, my name is Doug Ragan and I have been a high school chemistry teacher for fourteen years. Three years ago, I was approached by my high school principal and the conversation went like this,
Principal: "You are one lucky guy."
Me: "Really, why?"
You may have read Sarah Kong's recent blog post on inquiry on this site. I thought I would give a description of one way I incorporate inquiry learning into one of the chemistry courses I teach.
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.
Students choose a topic and select items to incorporate into a periodic table. Students explore trends related to their own topic and relate to the trends on the actual Periodic Table of Elements.
