Relative Reactivities of Metals

Last winter I watched a webinar put on by ACS and AACT called "NGSS in the Chemistry Classroom." As a result of watching that webinar, I took an activity that had NGSS Science & Engineering Practices (SEP) integrated into it and tried it out in class. In this activity, students are required to develop their own procedures and data tables.

Vocabulary Instruction

Harry Potter and the Elephant Toothpaste Potion

The “Elephant Toothpaste” experiment is a very popular, albeit messy chemistry demonstration.  To carry out this experiment, place a 250 mL graduated cylinder on something that you wouldn’t mind getting messy.  Next, add 7

Types of Chemical Reactions

I expect that most high school chemistry teachers assign some type of laboratory related to types of chemical reactions including synthesis, decomposition, single replacement and double replacement reactions. I have used several published versions, but I am sharing my modifications.
