The thorny problem – a Japanese beetle lesson plan.

Biology/Life Science Activity – Grades 7-9

Japanese beetles insect behavior

Japanese beetles are a thorn in the side of rose growers everywhere. The invasive species, introduced to North America in the early 1900s, causes crop and landscaping damage in the tens of millions of dollars each year, and roses are not immune. But are all types of roses the same in the eyes of the beetles?

This simple, one-day activity answers that question while helping young scholars build the skills to gather, analyze, interpret, and report scientific data. A 20-point scoring rubric is included for easy grading.
