Starring 3 amazing chemical reactions! Abe’s Makeover TEACHER NOTES BELOW Materials Per Group (2 or 3 students): old penny, vinegar (~20 mL, in small cup/beaker), salt (in baggie, labeled; with plastic spoon in baggie), stir stick (popsicle stick), safety glasses, Student Handouts Procedure: Have students examine their dull penny. Talk about how chemical reaction #1 has already occurred-the penny became dull (think of what it looked like the day it was made). Fill in Part I. on the handout as follows: Have students write down the reactants and products for Part I. on their handout as shown on the PowerPoint. Make sure they space their writing as shown, to leave room for what’s next. The red circle that appears first gets your students to notice where the halfway mark on the line is, to help them with spacing. Next, write in plain English what the formula means, as shown on the ppt (“translation”). *Caution- all students must wear safety glasses for the entire lesson since one product today is hydrochloric acid; weak, but still acidic.
