Many of us have molecular kits we only use once a year. Dust them off and find new lessons to use them in!
Melissa Hemling shares her favorite manipulatives along with cheap at-home alternatives to help students visualize VSEPR.
Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations. Though demonstrating the presence of these forces in a simple and explicit manner can easily be done, I wanted to change how I introduced IMFs a bit this year by focusing on a more data-to-concepts approach.
Erica Jacobsen shares highlights from the April 2019 issue of the Journal of Chemical Education.
Card sorts are a great way to achieve a number of classroom objectives. They can be used as a review activity or they can be done during the middle of a lesson as a type of formative assessment. Sorts can encourage students to work with other students or can even be used as a type of exit ticket. I decided to use the strategy about two thirds of the way through a unit on covalent and ionic compounds and lewis structures. I knew there were items we did not cover in the sort but I was curious to see how they would approach these unknown topics.
