What are FIVE tools that we use to help us extend our senses when making quantitative observations?
Think of the fives senses: sight, sound, taste, touch, smell. Next, think of five or more scientific measurement devices that provide ways of making highly sensitive quantitative measurements that are related to those senses.
For "smell", and taste, which involve the identification of trace amounts of specific molecules, there are devices like infrared spectrophotometers and gas chromatographs. Piezoelectric and capacitive transducers can measure small forces (i.e, touch). I'm sure you can think of how light and sound measurements can be made quantitatively
Ok thank you. At first I was confused, but then I realized that I was mixing up quantitative and qualitative. It makes sense now. Thanks!
