By the end of this course participants will…Understand how local phenomena interact with the Next Generation Science Standards, climate change, ecosystems, and people in a community.Experience how local phenomena and field investigations can build scientific understanding.
This Google Folder leads to an online module that is designed for students to learn concepts of evolution, descent with modification, natural selection, and more. There is both a student guide and a teacher's guide to help navigate through the module. Google forms are also available to support learning throughout the module. Interactive activities and simulations are also included for students to enjoy and learn from.
After studying the basics of enzyme function, students will be exposed to the history and evolution of lactose intolerance/lactase persistence. Both whole group and individual activities will ask students to interact with the concept. They will conduct a lab to understand the role of enzymes in lactose digestion and communicate their knowledge by creating a public health poster.
It is well known that mutation is the ultimate source of variation. Without adequate variation, plant breeding is impossible. To start a breeding program, the breeder must find the appropriate genotype (containing the desired genes) from existing variation, or create the variation if it is not found in nature. Mutagenesis is the process by which new alleles are created. The purpose of this chapter is to discuss mutagenesis as both a technique and a breeding method. The newly created mutants may be used as parents in future breeding programs, in which case mutagenesis is a breeding technique as a source of variation. However, an induced mutant can be systematically processed through conventional breeding steps to be released as a cultivar, hence making it a breeding method (mutation breeding). Mutations arise spontaneously in nature and are pivotal in natural evolution.
