Science Practice: Obtaining, Evaluating, and Communicating information

Food Dyes as Acid-Base Indicators

Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.

The Start of Another Year.....

Chad Husting explains how he used two hands on activities to get a sense of where his students were at within the realm of labwork and the scientific process as school began. 

The Empirical Formula of Magnesium Oxide Lab: A Successful Failure, Next Steps—and an Important Lesson

Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.

What do you want to know about your students' chemical thinking? Categorizing chemistry formative assessments

In order to teach chemistry effectively, we must ascertain what our students are thinking about chemistry and make a decision regarding what to do with what we learn. Formative assessment questions provide a useful lens into students' minds regarding what they are thinking about chemistry. Let us consider then, how categorizing formative assessment questions could help us plan out our classes more deliberately, in order to better design purposeful written formative assessments that align with our curricular goals. If you would like to learn more, please join us for a ChemEd X Talk about formative assessment question categories that we will be leading on Thursday May 26 at 7:00 PM EST.
