The Teacher Guide is the driving and unifying component of this unit, Chemical Reactions and Matter. In this unit, students investigate the phenomenon of matter and its involvement in chemical reactions. The subtitle of this unit is How can we make something new that was not there before? This is a phenomenon that students experience when they add a bath bomb to water and see that a gas is released. What causes this to happen? How does matter undergo chemical reactions? This unit allows students to observe this phenomenon in detail and then start asking questions, formulating explanations, setting up and conducting activities and research, and working with classmates to analyze the shared experience and formulate new questions and developing new strategies for answering them.
