Get Squirmy

Overview

Objectives/Goals My objective was to test a mealworm's resperation rate in various temperatures and see at which temperatures their respiration rate is the highest. I used the temperature with the highest respiration rate to see if it affects the rate at which the mealworms mature and I compared to mealworms at room temperature. Methods/Materials I used beakers,3 large beakers, ice, the ISOTEMP 205 water bath, 100 mealworms, a ring stand, thermometers, Vernier LabQuest2, Vernier CO2 gas sensor. For the first part of my experiment, I tested mealworms in a Nalgene bottle. I plugged a CO2 gas sensor to my LabQuest2 and then attached my CO2 sensor to the Nalgene bottle that held the mealworms. Then I submerged the Nalgene bottle with the worms in ice or in a warm bath, depending on the trial. I read and recored the data. Results At 115F, the mealworm's respiration rate was higher than at 35F. The mealworm's growth rate is faster at 120F temperature than at room temperature. Conclusions/Discussion My project can benefit people around the world. I have proven that keeping mealworms at hotter temperatures will increase their growth rate therefore providing food at a faster pace for the perople that depend on these worms to survive.
