Performance Assessment

In this lab experience, students carry out an investigation to determine which solid fills a balloon with gas when reacted with 2 M acetic acid. They write the full, balanced chemical reaction, predict the products given the reactants and identify when no reaction has occurred. The four versions of this lab focus on evidence of a chemical reaction. Students dig deep into this concept and explore production of gas when they react acetic acid with a base. Students determine that in some trials when acetic acid is mixed with various white solids, there is no evidence of a chemical reaction. The five combinations serve as an excellent teaching point when looking for evidence that reactants have turned into products in the flask. Watch your students have fun and learn great skills with these labs!
