A student is conducting an experiment to determine how cold temperatures affect the growth of tadpoles in a tank of water. Which instrument would be most appropriate to use in this experiment?
a calibrated bulb thermometer that has a readout from –15°C to 25°C
a calibrated digital thermometer that has a readout from 50°C to 250°C
an uncalibrated bulb thermometer that has a readout from 0°C to 100°C
an uncalibrated digital thermometer that has a readout from –10°C to 100°C

a calibrated bulb thermometer that has a readout from –15°C to 25°C

Reason: it is calibrated (accurate) and its range covers the cold temperatures relevant to tadpole tanks. The calibrated digital option's range is far too high, and the uncalibrated thermometers may give unreliable measurements.
