In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine. During the first part of the lesson, learners visit three stations: Combustion, Compression, and Intake to discover what happens as different forces act on air. In the second part, learners build a model of a turbine engine. This activity emphasizes the scientific method including prediction, observation, data collection, and analysis. This lesson plan includes instructions on how to set up the stations, discussion questions, diagrams, black-line masters, and sample worksheets for learners.
