In this chemistry activity (page 8 of the PDF), learners will identify the instances of physical change, chemical change, and solutions while making homemade soda pop. They will watch as yeast in sugar water converts some of the sugar into carbon dioxide, creating a carbonated drink. Although this activity was created as a post-visit for a workshop about chemistry in cooking, it also makes an excellent stand-alone activity!
