Lab Investigation: Exercise and Heart Rate KEY IDEA: Heart rate and breathing rate both increase during exercise to meet the body’s increased metabolic demands. Temperature can alter the amount of oxygen needed for respiration and the amount of energy used. Introduction: In this lab you will slowly change the water temperature of a fish and determine how changing the temperature affects the fish's respiration rate.Recall that HOMEOSTASIS refers to an organism's ability to respond to environmental changes and maintain its own internal balance. Hypothesize how submerging your face in cold water while holding your breath may impact your resting heart rate. 6. The faster the rate of respiration, the greater the rate of oxygen use and the greater the rate of carbon dioxide release (BBC, 2014). Breathing Rate Lab Aim: How does increasing the number of running laps affect the breathing rate per minute? Normally, the breathing rate does increase with the amount of exercise and/or movement one does. My breathing rate actually started at 18 BPM, slowed to 17 BPM, and then went back to 18 BPM. This resource is designed for UK teachers. The respiratory rate contributes to the alveolar ventilation, or how much air moves in and out of the alveoli. docx, 13 KB. Investigation #11- Transpiration. The following lab represents an investigation to help you solve the Tri-Lakes problem.
