misconceptions/discrepant events

Misconceptions refer to common, erroneous beliefs that students use to understand and explain the world around them. Such assumptions often become entrenched and resist modification by traditional instruction. A discrepant event is an experiment, demonstration, or other occurrence that challenges a misconception by producing a result counter to that predicted by the mistaken belief. When this happens, students are forced to reevaluate and adjust their conceptual framework in order to account for the discrepant event.

With most of us stuck at home to combat the recent outbreak of COVID-19, I thought it might be a particularly good time to do some simple chemistry experiments that use only items found around the home (well, more like purchased at my local grocery store).

There are a variety of types of assessment, including diagnostic, formative, and summative. The results from assessments have the potential to give teachers and students valuable feedback about progress toward learning objectives.
Liquid Nitrogen Cloud
The Liquid Nitrogen Cloud
// Friday, July 26, 2019 • Tom Kuntzleman
One of my favorite experiments to conduct is the liquid nitrogen cloud. As long as you can get some liquid nitrogen, it is incredibly easy to carry out. All you have to do is pour some hot water into liquid nitrogen and a massive cloud results. Check it out (also, be sure to check out the video posted further below):
