Collisions is a system of eight digital games, grounded in the rules of chemistry, that can be used to introduce, teach, and review more than 50 key concepts in your chemistry classroom. Collisions makes abstract concepts tangible by allowing students to visualize and manipulate the building blocks of matter, while providing a safe space to make mistakes and learn by introducing content through gameplay. On March 24th, 2021, Jen Lee presented a ChemEd X Talk about how instructors can use these games with their high school and college students. Besides explaining how the games work and interconnect, she outlined how to find and use premade lesson plans and answered questions posed by participants.

ChemEd X Talks with Katy Dornbos about how she has transformed the way she is assessing her students - particularly on exams. Her new method of assessing was born from her desire to decrease student stress, minimize her grading time and keep the questions challenging enough to encourage deep thinking.

Chad Husting presented in a ChemEd X Talk and spoke about how he has transitioned to standards based grading during a pandemic! He shared some tips that have solved many of the problems that teachers struggle with including having a mix of face to face and virtual students and keeping up with late work, make-up work and missing assignments!

This demonstration offers an alternative to the disappearing rainbow demonstration using readily accessible materials.
Some of the challenges associated with virtual instruction include connecting with students and checking for understanding in real time. On February 2nd, Michael Farabaugh presented a ChemEd X Talk about how he uses the interactive features of Nearpod to create formative assessment items that provide valuable feedback and facilitate student participation. You can watch the edited recording of Michael's Talk and access the lesson he shared during the presentation here.
The authors revisit "flattening the curve" demonstrations published during 2020 to see how they could represent the impact of vaccinations on the COVID 19 battlefront. These demonstrations do not demonstrate the mechanisms of vaccines themselves, but are rather analogies to their potential effect on a population. In these analogies, gas production still represents illness, but this time people are represented by objects added to the solutions which either enable gas production (unvaccinated individuals) or do not enable gas production (vaccinated individuals). These simple experiments are best used as stand-alone demonstrations, and links to videos are included in this writeup.
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 classkick.com 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.

Providing students with meaningful feedback greatly enhances their learning and achievement. With the move to online and hybrid formats, teachers have had to scramble to modify their usual process for communicating that feedback. On January 21, 2021, Ariel Serkin presented in a ChemEd X Talk about the process she is using and how she is providing feedback to her students remotely.
