ESS Student Intro Activity 2 6. Now you are ready to recreate the experiment that happened before you arrived on the scene. Researchers left their data table behind. It is full of clues that you have deciphered. Use your answers from Questions 3–5 to design an experiment that matches the one completed by the researchers. Your experimental design will tell the story of the beetle experiment. Use the following template to organize your information. Do your best job, using the information you have analyzed in Model 1. You will have a chance to redesign your experiment later in this activity. Independent (manipulated) variable (the one the scientist is changing): Dependent (responding) variables (the ones that are responding to the scientist’s changes): Controlled variables (list as many as you can): Experimental Question: Your experimental design: Use labeled drawings or a list of steps.

Independent (manipulated) variable: Type of food (leaf litter, dung, or carcass)

Dependent (responding) variables: Number of beetle species, number of beetles per species, beetle behavior (foraging, mating, etc.)

Controlled variables:
1. Temperature and humidity level
2. Size and type of containers or habitats for beetles
3. Lighting conditions
4. Time of day for observations
5. Duration of the experiment

Experimental Question: How does the type of food affect the diversity and behavior of beetles?

Experimental Design:
1. Set up three separate containers, each with the same size and type of substrate to mimic their natural habitats.
2. Label each container as "Leaf Litter," "Dung," and "Carcass."
3. Place a predetermined amount of leaf litter, dung, or a carcass in each respective container.
4. Collect beetles from the field and distribute them evenly among the containers.
5. Observe the beetles for a set period, noting the number of species present, the number of beetles per species, and their behaviors.
6. Repeat the experiment multiple times to ensure accuracy and reliability of the results.
7. Analyze the data collected to determine the impact of different food types on the diversity and behavior of beetles.
