Meal worm Stimuli

As we continue through our arthropod unit, we will use the larva stage of the darkling beetle to observe through metamorphosis and create a class data table. In the first lab, students discover how meal worms behave in response to six different stimuli. They observed different innate behaviors to wind, touch, moisture, introduction of food and ability to burrow. Physical characteristics and anatomical directions were noted by the children and details of appendages including the mandibles were identified by using a hand lens. The meal worm’s speed was calculated through a timed test. Students will check their assigned tub twice a week to collect data on larva as they progress through the stages of complete metamorphosis.
