About STEM Cases

Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.

Realtime reporting icon

Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap

Time icon

STEM Cases take between 30-90 minutes for students to complete, depending on the case.

Save icon

Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.

Grades icon

Multiple grade-appropriate versions, or levels, exist for each STEM Case.

Handbook icon

Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
