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
