Middle school students, as scientists, investigate particle motion and forces to answer the following driving question: How is energy transferred to the gas particles during ignition? Students are continuing to investigate the phenomenon of the successful model rocket launch from lesson one. Students watch a video and analyze diagrams to collect information about what is happening inside the engine of the model rocket during ignition. Students identify evidence of energy in the video and consider if a chemical reaction has happened. To gain more information about the connection between chemical reactions and energy, students observe three chemical reactions and measure temperature change. Students use this information to revise their models showing the transfer of energy in the model rocket system.
