Elaboration
- Sample opportunities to support student inquiry:
- How would you design an experiment to test the effects of various concentrations of caffeine on heart rate in Daphnia (water fleas)? Can your conclusions be applied to other organisms? If so, are there any limitations?
- Devise a hypothetical experiment to test the claims in a scientific article about allergies.
- Design an experiment to test foods for various nutrients (e.g., proteins, carbohydrates).
- How would you design an experiment to test the heat conduction or insulation properties of objects or materials (e.g., heat exchangers, R values of building materials, thermoses)?
- How would you design an experiment to test glue strength in wet or dry environments on face, edge, or end grains (tangential, transverse, radial) of wood?
- Design an experiment to test the effectiveness of baking soda and different types and concentrations of vinegar in producing CO2. What risks are associated with gas production in an enclosed space?
- Design an experiment to investigate how components of the fire triangle contribute to combustion.
- Discuss ethical issues related to the use of living things in experiments, considering related safety precautions.
- Design a procedure to test the accuracy of instruments such as blood pressure monitors or smoke alarms. Discuss the importance of measurements being accurate (i.e., close to a given standard or known value).
