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. I provided the materials and equipment and only asked that they present their procedure to me before beginning. For some of the students I encouraged to them rethink their procedures to be more efficient (for example, do we need to react Mg with Mg(NO3)2??), whereas for others, I let them be so we'd have a point of discussion after the lab.
This week I had my current Honors Chemistry 1 students work through the lab. Every student was engaged and appropriately challenged. I posted a photo of a student's well plate on Twitter which led to AACT and another Twitter colleague seeking a copy of the lab for others to use a resource. I wanted to share it here in addition to it being available on AACT's website.
Enjoy!
