Summary
Highlights
The video starts by welcoming viewers to Lesson 2.3 and emphasizes the importance of having all necessary materials ready. This includes logging into the Amplify digital platform for Lesson 2.3, Activity 1, or having the Amplify investigation notebook (pages 46-47), or simply paper and a pencil if not using the digital platform.
The warm-up activity involves creating a model to predict how potential and kinetic energy change when two magnets repel. Participants using the digital platform will find directions there, while those with the investigation notebook will refer to pages 46 and 47 for guidance. The goal is to visually represent energy transformations, building on concepts from the previous lesson.
The activity requires shading bar graphs under each panel to show predictions of potential and kinetic energy at different times. Additionally, participants must annotate their models to explain their energy choices. This includes jotting down notes to justify why they've represented energy in a specific way and potentially adding magnetic field lines to aid in understanding the system. The activity involves three steps, similar to a previous lesson, and helps prepare for Activity 2.
