Dancing Popcorn

This is a science activity geared toward the middle school student that uses Inquiry-Base-Learning to address the essential questions; How do we know when a chemical reaction has occurred? And How do observations, evidence and data allow us to come to valid conclusions? The activity uses low cost or no cost materials that allows students to carry out a series of observations that will allow them to make valid conclusions based on evidence. Analysis questions are designed to allow students to use discipline- based vocabulary in carving their responses. The activity is also a way to create interactive learning of vocabulary. Lastly, their are teacher suggestions that will enrich the experience by addressing lab skills and development of measuring skills if appropriate materials are available. Materials include within the four pages are: the Procedure and List of Materials page, Data and Observation page, Analysis Section, and Teacher Notes. The following NGSS that are supported by this lesson are: MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred,
