Students established their Baggie Garden experiments today, setting up their experiment bags and one or more experimental control bags. We began class with a brief overview of the day, and then students worked in groups to write a detailed experimental procedure. Once their procedure was reviewed and teacher-approved, the students assembled their baggie gardens, using the resources available to test their hypotheses.
For groups testing temperature as their manipulated variable:
- Freezer -10C
- Refrigerator 9C
- Room 23C
- Warm box 30C
Tomorrow we will make our first experimental observations and then discuss how to organize how to collect and organize data relevant to each group’s research question.
