This is an ILS based on the "Learning by critiquing" Template provided at the Marathon Summer School 2019, Athens, Greece.

It consists from the below phases:

1. Learning goals ("Meet Martha")

2. Orientation - General ("Challenge accepted!")

3. Orientation - Specific ("Concentrate to the solution")

4. Orientation - Critical reflection ("Lisa and Thomas")

5. Conceptualisation ("IF...THEN")

6. Investigation I ("Checking the hot potato")

7. Investigation II ("Transformations")

8. Conclution ("To drink or not to drink")

9. Discussion I ("The last challenge")

10. Discussion II ("What Else?")

Main Tools: Quest, Quiz Tool, Question Scratchpad, Hypothesis Scratchpad, Viewer, Experiment Design Tool, Table Tool, Conclusion Tool, Teacher Feedback.

Pedagogical aims:

1. To help students understand the phenomenon of osmosis and its uses in everyday life.

2. To help students understand that reckless mimicry may leed to dangerous situations.

Main scenario:

Helen challenges John to drink salty water. Will this has an impact on his health? Students will face the phenomenon of dehydration caused by the cells' osmosis. Lisa mimicried Helen and she decided to challenge Thomas to drink deionised water. Is it safe? Students make hypotheses about what happens when a cell's environment is hypotonic or hypertonic. Then, they write down the results of two experiments: 1) osmosis in a potato and 2) osmosis in cells. Finally, the students write their conclusions and relate their findings with everyday situations (osmosis in everyday life and especially osmosis in cooking).
