The teacher then makes a quick transition to the next lesson, which deals with the connection between simple machines and the body. She encourages students to talk about the jaw and to compare chewing to a nutcracker and to arms and lifting. She asks open-ended questions, and students do most of the talking. Students quickly get the point and eagerly introduce new ideas about the relationship of body motions to the principle of levers. Students who speak support ideas and respond respectfully to the views of others.
All discussion is in Spanish.
Next, the teacher asks students to write. She instructs students to use all of the scientific terms they have learned. The writing can be in either Spanish or English. The class needs a little prompting and quickly falls silent as they focus on their written work. Highlights of the Lesson Instruction, including the use of scientific terms, is conducted exclusively in Spanish.
