They create models to explain the relationships of parts in black boxes and a whimsical device called a humdinger. Later in the module students design and build model carts that respond to a series of engineering challenges. They observe and compare the outcomes of experiments, identify relations between independent and dependent variables, and make predictions using the results of their experiments. Comparing Communicating Observing Students use techniques that allow them to see details about the world that would otherwise be difficult to observe. Students then use these techniques inventively.
Students learn metric measurement.
