How an investigation works
The seven ADI stages
Every ADI investigation moves through the same seven stages, so students learn to plan, test, and argue from evidence the same way from kindergarten through high school.

Explore a real phenomenon and the guiding question, and sketch an initial model.
2
Ideas
Gather key ideas
Read short texts on the science, concepts, and practices behind it.
3
Plan
Design the investigation
Tool talk, then teams plan their investigation and get peer feedback.
4
Do
Collect the data
Carry out the plan, collect and analyze data, and form a tentative answer.
5
Share
Argue from evidence
Draft an argument, defend it in an argumentation session, and revise.
6
Reflect
