Lesson Plan Overview Recommended Grade Level: 8 Discipline: Life Science/Biology Topic: Insect Behavior Lab Activity Title: Rose Color Preference in Japanese Beetles Submitted By: Karen McCabe 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. Lesson Objectives: • Students will conduct a scientific investigation. • Students will observe insect behavior. • Students will determine rose color preference for Japanese beetles, Popillia japonica. National Science 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 LIFE SCIENCE: REGULATION AND BEHAVIOR • All organisms must be able to obtain and use resources, grow, reproduce, and maintain stable internal conditions while living in a constantly changing external environment. • Regulation of an organism's internal environment involves sensing the internal environment and changing physiological activities to keep conditions within the range required to survive. • Behavior is one kind of response an organism can make to an internal or environmental stimulus. A behavioral response requires coordination and communication at many
