We know this because oxygen is being used up more quickly. Questions 1. What would happen to the rate of aerobic respiration in small animals, such as insects, with an increase in temperature? The answer to this question is your hypothesis. 2. State the aim of your investigation. (1) (1) 3. Design a method to test your hypothesis. Write out your method step by step. (4) 4.
