Build an Oxygen Plant
Students create models of an oxygen-delivery system and relate it to the function of the human circulatory system.
Students understand why certain behaviors are unhealthful.
circulatory system, heart, health

We have left his lesson live on Education World because the information on the pages is for the teacher's use only; it is still valuable information that can be used to create an engaging lesson for students.
Display to students A Conceptual Model of the Circulatory System [archived copy], or draw the model on yhe chalkboard.
Explain to students how the factory model delivers oxygen.
Organize students into groups, provide each group with an assortment of craft materials, and ask each group to re-create the model.
When the models are finished, have students brainstorm things that could go wrong in the process and interfere with the delivery system. (See things that could go wrong in the factory model [archived copy] for suggestions.)
Ask each group to alter its model in a way that interferes with the delivery process.
Discuss the results.
Display a diagram of the human circulatory system and encourage students to make analogies between the factory model and the parts of the human circulatory system.
Ask them to relate the things that went wrong in the factory models with things that can go wrong in the human circulatory system.
Discuss with students the things they can do to avoid those problems and keep their hearts and circulatory systems healthy.
