This leads into an exploration of the science behind the function of machines, including both simple machines and how machines work together to help people accomplish a task. Each Learning Set is also framed by a question. These sub-questions support the driving question and sequence the concepts that students will be exploring. Here students are introduced to computer technology of force sensors and DataStudio software to help them develop a concrete understanding of force and the interaction between forces. These questions follow a logical inquiry into studying mechanical advantae and support students in thinking about important concepts as they build toward an answer for the driving question.
Students participate in several investigations while exploring each stage of the driving question.
Students begin by examining how evidence can be used to support conclusions from investigation. They first focus on collecting data of force and distance in simple machine investigations, and creating graphical representations to analyze the data. Students think about the strength of their evidence based on the quality and consistancy of the data they collect. They also develop skills of asking good reasearch questions and identifying variables to be tested in these investigations. Students practice these skills as they design and conduct their own investigation of mechanical advantage later in the project.
