Whiteboarding in a Virtual Classroom with Melissa Hemling

On January 26, 2021, Melissa Hemling presented a ChemEd X Talk about “whiteboarding” in a hybrid or virtual classroom. Students collaborate in small groups on to digitally analyze data, create and modify models, and/or complete practice problems. Melissa shares how she uses the digital whiteboards to gauge student understanding and pinpoint misconceptions like she did pre-COVID. You can watch the edited recording of Melissa's Talk and access the document she shared during the presentation here.

Creating Interactive Particle Diagram Activities for Online Instruction

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.

Science Modeling Talks Podcast

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.

Measurement, Uncertainty, and Significant Figures 

As high school teachers, we know that understanding how measurement works is crucial for lab skills and for understanding significant figures. We think measurement should be an easy topic for students to learn; especially because we know that teachers begin working with students in elementary school to teach these skills. However, I, and many other teachers, have spent countless hours teaching and reteaching a seemingly simple skill.

Gas Laws and Deflategate

If you are looking for ideas to create an authentic opportunity for students to apply their knowledge of gas laws while integrating some of the most important science practices, then this activity may fit your needs.

Equilibrium Snowball Fight

For dynamic equilibrium, I like to use a physical analogy that pits students against each other in a classroom-wide “snowball” fight. Not only is this activity great for building students’ conceptualization of dynamic equilibrium, it is also really fun!

DIY Whiteboards for Less Than $2.00/Each.

Whiteboards are great learning tools in a science classroom. With these instructions, you can make eight 24-in x 24-in whiteboards for less than $2.00 each! Instructions for simple whiteboard stands are included.

Elements, Compounds, and a Vocabulary Card Sort

How many of you could recite, word for word, a definition you learned in school? When you first memorized the definition, you could state “inertia is a property of matter”, or “density is mass over volume.” However, you struggled to apply it to a new situation and maybe you were unsure of how to construct a model of what it meant.

Confessions of a Part-Time Modeler

In the summer of 2016, there was a Modeling WorkshopTM for High School Chemistry just before BCCE in Colorado. I already had planned to go to BCCE, so I took the plunge. Two weeks of daily instruction and labs in student mode as well as teacher mode debriefing was exhausting and exhilarating at the same time. I left with a folder and flashdrive of curriculum resources provided by AMTA (the American Modeling Teachers Association.
