Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.
In this lab, students connect the workings of an electrochemical cell in the lab with the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process. Although this lab was previously highlighted on ChemEd X, there are now virtual options offered!
Are you having a hard time describing 3-D drawings or or showing motion of particles in your digital assignments? GIFs can help!
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
Many teachers have students draw models and diagrams to help them illustrate how matter behaves. Teachers can uncover and address possible misconceptions quickly using this strategy. The author describes how to create interactive particle diagram activities that are easy for students to use online. This strategy is applicable to almost any particle diagram and should be useful for teachers during virtual lessons.
Living at the macroscopic level, it’s no surprise that understanding and effectively communicating chemistry concepts can often be a challenging endeavor. Attempting to rationalize our observations through particle-level interpretations requires us to think in less intuitive ways that often create a cognitive barrier for our students. And for good reason.
Particulate diagrams are all the rage in chemical education. Learn simple tricks to create your own!
This week marks the launch of a new science education podcast called, Science Modeling Talks. The podcast provides some history on the Modeling pedagogy and access to resources, as well as entertaining anecdotes from award-winning educators. The podcast is free and available on a variety of platforms.
With few materials available to complete wet labs in my school, I have to be creative with covering lab concepts in my AP chemistry course. I was looking for a way to make sure my students were getting the idea of the macroscopic changes that take place in a galvanic cell without necessarily being able to do the wet lab. The particulate model that is part of the Energizer Lab inspired me to write an end of unit assignment for my students using Stop Motion video apps.
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.
