BRACHYBIO! LINKING TEACHERS, STUDENTS AND SCIENTISTS IN PLANT RESEARCH
BrachyBio! Linking Teachers, Students and Scientists in Plant Research
BrachyBio! Goals:
Bring real scientific research to science classrooms using plants
Create a mutually-beneficial partnership where all groups are able to learn with and from one another to advance scientific understanding of plants
Demonstrate to students and teachers that scientific inquiry is relevant and can be used to solve important social and environmental problems
BrachyBio! Goals Bring real scientific topics to the classroom
Students can understand the importance of plant science by relating to the roles that plants play in their daily lives as sources of food and energy.

Students find and Catalog Mutants
Pale Green Mutant Variegated Mutant & Early Flowering
•Pigmentation related to photosynthetic pathways may be applied towards understanding photosynthetic development.
• Increased branching may contribute towards increased plant yields with potential applications in biofuel development.
Wild Type Pale Green Highly Branched
• A majority of the plants will be wild type. These plants can be used for many additional lessons in the classroom.
Discuss Applications of Mutant Phenotypes
Students observe and record physical characteristics

Professional Development for Science Teachers
•Develop content knowledge in hard-to-teach topics like genetics, heredity, and photosynthesis
•Work as an annual cohort to develop lesson plans that integrate new content knowledge into the existing curricula•Receive classroom support, web-based resources, and equipment to implement new lessons into their classrooms•Access to an online database where students can upload their data and compare it to data generated in classrooms across New York State.
Students: making discoveries that extend beyond the classroom
•Students are making discoveries! • They work to standardize growth
conditions and collect meta-data on environmental conditions like temperature, light, humidity.
• They observe and catalog unique phenotypes caused by random genetic mutations in the DNA of Brachypodium plants.
• Through a shared database, they have the opportunity to compare their results with other classrooms. They may discover how environmental differences influence phenotypic expression.

Connecting to BTI Scientists
•Student work is generating data that scientists will use to continue to breed and develop important food crops.
•Students are exposed to agricultural issues and research in ways that are relevant and timely.
How do teachers bring BrachyBio! To their classrooms?
•The BrachyBio! website (www.bti.cornell.edu/brachybio) and curriculum materials have been developed by teachers, scientists and science educators for use in the middle and high school science classroom. The curriculum may be taught as a stand-along unit, or integrated into existing units including genetics and heredity, photosynthesis, or growth and development, all using scientific inquiry.
