identify data sources, plan and choose equipment or resources to perform a first-hand investigation to design experiments that could test the observations of one of:
- van Helmont
- Hales
- Priestley
- Ingen-Housz
- Senebier
- Saussure
- Choose the experiment you wish to replicate and determine the type of data you need to collect. Plan your specific design for the experiment in light of the equipment and resources you have available, making modifications to the design of the investigation if necessary. Perform the experiment, recording the data appropriately. The experiment could be as simple as counting the bubbles of oxygen gas produced by an algal plant in water exposed to various light intensities to reproduce Ingen-Housz’ experiment.
