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](/Assets/img/blank.gif)
Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap
![Time icon](/Assets/img/blank.gif)
STEM Cases take between 30-90 minutes for students to complete, depending on the case.
![Save icon](/Assets/img/blank.gif)
Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.
![Grades icon](/Assets/img/blank.gif)
Multiple grade-appropriate versions, or levels, exist for each STEM Case.
![Handbook icon](/Assets/img/blank.gif)
Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
