Disha Edge
The water observation lab: Investigation lead
A school compares fictional water-sample records. Do not taste samples or decide whether water is safe to drink. You play the investigation lead and work through 9 short levels, about 14 minutes in all. Where you start: Change one condition at a time. A small observation cannot prove drinking safety. The work connects to careers such as environmental scientist and laboratory technician, general science. It is free, and your reflection stays private.
Your path
Compare observations without jumping to a claim.
Private stars
A star marks a step you completed. Your answers and speed do not change it.
