Build a Boat Collaboration

Kristin Gregory | Sat, 08/08/2020 - 18:05

As many teachers are preparing to teach online, we are revisiting posts from the ChemEd X archives like this one that might be of help. The original Build a Boat challenge was used to help create a classroom culture of teamwork and growth mindset. The author has updated the Build a Boat activity by providing a modified slide show presentation specifically to help those teaching remotely this fall. 

A Multi-Colored Equilibrium Experiment

This unique microscale gas collection technique provides students with reasonably good data in a short period of time. Students have more time to analyze the data and communicate their findings. 

Seeing Chemistry in a Different Light—FLIR Thermal Cameras in the Classroom

Ben Meacham | Wed, 01/15/2020 - 10:43

Before trying to use a piece of equipment, it’s worthwhile to have a basic understanding of how it works. To put it simply, FLIR cameras primarily deal with the infrared part of the EMR spectrum. The camera detects infrared energy and converts it into an electrical signal, which is then processed to produce a thermal image on a video monitor.
