+ ward ' s science Page 1 Rose Color Preference in Japanese Beetles Submitted by: Karen M. Recommended Grade Level(s): Appropriate for: Grade 8 Time Requirements: Activity Time: 90 minutes Teaching Topics & Concepts: • Life Science/Biology • Insect Behavior Objective: • Students will conduct a scientific investigation. • Students will observe insect behavior. • Students will determine rose color preference for Japanese beetles, Popillia japonica. Standards: Science as inquiry: All students should develop abilities necessary to do scientific inquiry. • Identify questions that can be answered through scientific investigations • Design and conduct a scientific investigation • Use appropriate tools and techniques to gather, analyze, and interpret data • Develop descriptions, explanations, predictions, and models using evidence • Think critically and logically to make the relationships between evidence and explanations • Recognize and analyze alternative explanations and predictions • Communicate scientific procedures and explanations • Use mathematics in all aspects of scientific inquiry Overview: Japanese beetles are the "thorn in the side" of rose gardeners everywhere. As a child, part of my allowance was earned by picking the beetles off of my mother's rose bushes. I observed that some rose bushes seemed to have higher populations of beetles than others and thus sustained more damage. I often wondered why the beetles seemed to prefer one bush over another. This experiment will help to determine if color is the variable that caused the differences I observed. Materials: • 6 Japanese beetles, Popillia japonica • 6 plastic shoe box size containers with lids • 6 four inch cuttings (including at least one open bloom) from the same yellow rose bush • 6 four inch cuttings (including at least one open bloom) from the same red rose bush • Stopwatch This content is being brought to you by the Ward's World, Science By You program.
