Investigating Brassicas Around the World with Wisconsin Fast Plants - Open Source GRC Lesson
This investigation begins with a phenomenon that is evidenced in most every produce aisle: Many of the vegetables that botanists classify as Brassica look and taste different. This investigation aligns with middle and high school Next Generation Science Standards as well as with agricultural science Plant Career Path Standards. Provided as an Open Source Lesson in Gather-Reason-Communicate format, this investigation supports teachers as students learn about the life cycle of flowering plants, how environmental and genetic factors influence an organisms's growth, how humans influence plants through plant breeding, and how scientists can use classification as a tool for understanding relatedness among organisms.
This includes a lesson plan and supporting resources including videos, an interview, readings, and protocols.

- NGSS.HS.LS3.2 Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors. [Clarification Statement: Emphasis is on using data to support arguments for the way variation occurs.] [Assessment Boundary: Assessment does not include the phases of meiosis or the biochemical mechanism of specific steps in the process.]
- NGSS.HS.LS4.3 Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait. [Clarification Statement: Emphasis is on analyzing shifts in numerical distribution of traits and using these shifts as evidence to support explanations.] [Assessment Boundary: Assessment is limited to basic statistical and graphical analysis. Assessment does not include allele frequency calculations.]
- NGSS.MS.LS1.5 Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms. [Clarification Statement: Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. Examples of evidence could include drought decreasing plant growth, fertilizer increasing plant growth, different varieties of plant seeds growing at different rates in different conditions, and fish growing larger in large ponds than they do in small ponds.] [Assessment Boundary: Assessment does not include genetic mechanisms, gene regulation, or biochemical processes.]
- NGSS.MS.LS4.5 Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms. [Clarification Statement: Emphasis is on synthesizing information from reliable sources about the influence of humans on genetic outcomes in artificial selection (such as genetic modification, animal husbandry, gene therapy); and, on the impacts these technologies have on society as well as the technologies leading to these scientific discoveries.]
