In the “Airbag challenge” the students are tasked with developing a safe airbag for a car company. This formative assessment explores students’ thinking about the question “How can chemical changes be controlled?” The central concept in this challenge is the application is stoichiometry. Students are expected to use the numbers of moles of reactant consumed or product formed in a balanced chemical equation and to determine the change in the number of moles of any other reactant and product. Students need to use molar mass to convert mass of a reactant or product to moles for use in stoichiometric calculations or to convert moles from stoichiometric calculations to mass. Students use the ideal gas law equation to determine the numbers of moles in a sample of gas not at standard conditions.
Since I am unable to attend BCCE this year, I am asking for readers to consider two things to help me out. First, if you are attending BCCE, I hope you will submit a blog post to ChemEd X outlining at least one thing you learned. Second, I hope to find one or more teachers willing to try out Flipgrid and open our classrooms to share what we are teaching/learning.
Matt Vonk and Peter Bohacek have just created a handful of new chemistry activities that are based on interactive high-resolution video. These classroom-ready experiments have interactive tools so that students can perform the analysis and record data themselves. In some cases, students can even change variables.
I have written about Atomsmith before, but the new updates are worth another mention.
