It is always helpful to have a lab that can be adapted to meet the needs of students. The "Magnesium Lab" is one of these experiments.
In an effort to align an old VSEPR lesson to NGSS, I told my students that we were going to look at the data available from the real molecules on the pHET simulation we were using and specifically look for patterns. Finding patterns is a cross-cutting concept; one of the three dimensions of NGSS.
December is a busy time for many educators as we try to wrap up content before a long break and maybe incorporate fun activities into the curriculum. There are concerts, field trips, projects, presentations, and even variety shows to “celebrate the season.” However, I find that when schools try to get into the “holiday spirit”, they may unintentionally create an environment where students and teachers may feel excluded.
One aspect of Argument Driven Inquiry that has not been discussed here is the peer editing piece. I have succesfully tried it out with my own students.
Observe both an exothermic and an endothermic reaction/process as I use a modified propane torch in the video demonstration.
In an effort to implement the science and engineering practices of the NGSS, I have tried to introduce argumentation as a practice into my chemistry courses. I share some growing pains and what I have learned through the process in this blog post.
The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.
A simple, but tricky experiment is displayed. Can you figure out how the trick was done?
