...
- use your eyes. They are the best sensors we have.
- when exploring a new independent variable, conduct a small number of experiments over a wide range. For example vary the independent variable over 3 orders of magnitude.
- for initial experiments always analzye the data while acquiring it to reduce the risk of wasted effort
- learn how laboratory research system works. This includes sensors, data acquisition, process control, mechanical components, data analysis.
- conduct literature reviews to make sure that we are building on previous knowledge
- develop approaches for getting unstuck when it is unclear how to move forward.
- seek expert advice
- identify causes of failures and take steps to prevent those failures from recurring
- write about your methods, results, and your insights. The writing process provides a context to reflect on what you are observing and thereby gain new insights.
Checklist
- Calibrate turbidity meters and pumps before conducting experiments
- Clean the turbidity meter sample cells daily when conducting experiments
- Never leave an experiment running if it has a leak. Fix the leak first.
- Evaluate failure modes for your experimental setup and upgrade the design of your system if it is prone to failure
- Save your data files and method files on the AguaClara server
- Save process controller method files every time you make a change so you can go back to previous version if there is a problem
- Compare sensor readings with expectations and your own observations
