An infant on a farm has blue baby syndrome. As an EPA environmental engineer, students must find the cause of the baby's illness. Using environment data, students learn the importance of the nitrogen cycle and how human factors can impact nature.
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
|High School||This version is for general biology classes||40-50 min|
|AP||This version is for AP level classes||60-80 min|
Most content from the Expanded Handbook is included in the corresponding STEM Case.
|High School||The Expanded Handbook covers amino acid structure, ammonia dissolving in water (ammonia vs. ammonium), and the need for ATP in the synthesis of ammonia by nitrogenase, in addition to the concepts covered in the handbook section of the High School Case||15-20 min|
|AP||This Handbook is identical to the handbook section in the AP Case||20-25 min|
