Reflection: Discourse and Questioning Over-the-Counter Pharmaceuticals - Section 6: Evaluate

 

As students completed the lab there are several things I noticed and decided to revise for the next time I do the lab.  The revisions are found in this new document

One of the things I revised was the wording of the pre-lab questions to clarify what i was asking.  I also revised the procedure by having the well plates vertical instead of horizontal. 

I also noticed that students had a hard time with observing the appearance of each powder by looking and wafting once the substances were already in the wells, so I added that step to the part when they are grinding the tablets.

Finally I revised the instructions about solubility to help students better understand what they should be observing and recording.
