Student Activity based on the article “Best of Breed” from the May/June 2012 Our Ohio magazine.
Ohio Science Academic Content Standards
(Life Science Model Curriculum: Grade 8) In this student activity, students will explore the concept that “reproduction is necessary for the continuation of every species. Every organism alive today comes from a long line of ancestors who reproduced successfully every generation. Reproduction is the transfer of genetic information from one generation to the next. The ability to reproduce defines living things.” Students will discuss this concept while reading about genetic breeding of vegetable seeds. (Explanation and key terms are from the Grades P-8 Science Model Curriculum 030111.pdf.)
