STUDENT GUIDE
The Evidence Lab
A good story. But is it a good explanation?
A café queue. A navigation app. A very confident claim. Open the everyday mysteries, choose evidence that could separate the rival stories and build an investigation of your own.
Choose how to play
For Class requires Full. Complete the required decisions, evidence checks and explanations, then assemble the report. Printing and assignment-report downloads unlock when that work is current. Progress backups remain available throughout.
For Fun: explore at your own pace. Where Core and Full length choices are offered, they are available in For Fun. Exploration reports are personal records.
Type Class answers in the activity. Pasting and dropping text into response fields are off; names and progress-backup restoration remain available. Completion checks do not grade the quality of the written reasoning.
What you will do
- Try the warm-up and investigate the café and navigation-app cases.
- Design and critique your own investigation and connect evidence to public power.
- Complete the unfamiliar final challenge and review the Full investigation record.
Explain your decisions
Use a particular observation from the activity. Connect it to your choice and its consequence, and name what remains uncertain. Reconsider a view when the evidence warrants it, or explain why it still holds.
Save, return and submit
Check the activity’s save status. Download a JSON progress backup before changing websites, browsers or devices, and use its restore control to resume. Device saves do not synchronize between the two websites.
For Class, complete all required Full work and the final report action. Then use the report’s Print / Save as PDF or other readable export control and follow your instructor’s submission instructions. Downloading does not submit your work. A JSON backup restores progress; it is not the assignment report.
Sources and scope
The cases and data are fictional. They teach ways to test explanations; they do not establish real-world effects. A remaining uncertainty can be a well-supported result.
Use the source notes and dated records supplied in the activity when supporting a claim. Keep the difference between a fictional model and historical evidence clear.
