Mealworm lab report

Virtual Lab: Mealworm Behavior Worksheet 1. What are the two types of innate behaviors? 2. What is the simplest type of innate behavior? a. Learned behaviors b. Automatic responses to stimuli c. Responses to stimuli that bypass the brain d. Automatic responses that do not bypass the brain e. b and c f. b and d 3. List one instinctive human behavior and one reflexive human behavior. Table 1: Record your predicted behavior, the actual behavior, and the type of behavior for each stimulus applied to the mealworm. Stimulus Petri dish with light and dark colored sides Piece of cooked macaroni Touched by a Feather Beam of light shines on mealworm’s head Drops of ammonia placed near mealworm A piece of uncooked macaroni Touched by a metal paper clip Drops of apple juice placed near mealworm Air blown on mealworm’s head Slice of apple introduced Predicted Behavior Actual Behavior Type of Behavior Alarm beeps near the mealworm Cool water dropped on the mealworm Bran flakes are introduced A piece of banana is introduced 4. Review your recorded stimuli responses. What do you notice the instinctive behaviors have in common? What do you notice the reflexive behaviors have in common? 5. Select a two new stimuli you would like to test, one you think will results from reflexive behavior, and one you think results from instinctive behavior: a. What is the stimulus you think results from reflexive behavior? b. Why? c. What is the stimulus you think results from instinctive behavior? d. Why? 6. Read the following hypothesis, and then answer the questions: After observing that mealworms move toward cooked macaroni, but away from uncooked macaroni, you form the following hypothesis: “Mealworms only move toward food that is moist” You decide to test your hypothesis with dry bran flakes. You use a mealworm exposed to cooked macaroni as your control group, and a mealworm exposed to bran flakes as your experimental group. a. What is your independent variable? b. What is your dependent variable? c. Write out your prediction (a prediction is an “if…..then….” statement based on your hypothesis) d. Return to the lab simulation, and reset the stimuli until “Bran Flakes are introduced” comes up as a stimulus. Make your prediction and watch the video associated with the bran flakes stimulus. e. Was your hypothesis supported? f. Write one question that this raises in your mind. Write a new hypothesis based on this question and describe a new independent variable you could test to answer this question. ...
