In this demonstration, the teacher will perform a reaction between acetic acid (vinegar) and sodium bicarbonate (baking soda) in order to inflate a balloon and to introduce the concept of a chemical reaction to students. Students will observe the reaction, and identify indicators of chemical change as well as discuss the different types of matter that are involved.

In this lab, the students will work in cooperative groups to investigate how to make a scented, effervescent bath bomb and explore the chemistry needed to create them. Groups will test a variety of different variables in order to compare the reaction rate of each sample. Students will use the results to determine which variables are optimal for making and using bath bombs.
