MTTC Integrated Science (Secondary) (094) · Put your knowledge to work in context.
The MTTC Integrated Science (Secondary) (094) is one of the subject-matter tests in the Michigan Test for Teacher Certification program, delivered as a computer-based test of 100 multiple-choice questions. It carries endorsement codes DI and IP and is intended for candidates seeking secondary-level certification to teach integrated or general science rather than a single discipline such as biology, chemistry, physics, or earth/space science. The MTTC Integrated Science (Secondary) (094) case studies are 5 cases and about 2,768 words.
1Creek Dissolved Oxygen and Pasture Runoff
A secondary class studied a 2.4 km creek reach in June. Site A is 300 m upstream of a 12-ha cattle pasture with stream access; site B is 250 m downstream of the pasture.
