Presentation Transcript
Introduction to Articulating and Addressing a Chemical Question Reaction of Magnesium with Aqueous Acids A Simple Research-like Experience
Steps Asking a question Designing an approach Collecting data Analyzing data Revising plan and collecting more data if needed Summarizing data and preparing a report
Chemical Kinetics-Study of rates of reactions
Apparatus from earlier experiment Insert drawing of apparatus
Common early errors Using too much Mg and too much H2is generated [HCl] to high and rate too fast Not asking a focused question
Concluding Comments This is not research but an opportunity for students to address a question and design an approach Covers a topic typically covered in the class and lab Students have time to design an approach and to fail and redesign. Students are asked to draw conclusions and communicate results
