They've since updated their website. Here's the link to the full unit (this lesson is in there somewhere). https://learnaboutag.org/resources/lesson/whered.pdf
This lesson is a tool to demonstrate how various technological advances
have changed the tomato and the tomato industry over the years. The technology includes both selective
breeding and genetic engineering.
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.
Assessment Boundary: none

Comments about Including the Performance Expectation
This is part of a larger unit called:"Where'd You Get Those Genes?" from the California Foundation for
Agriculture in the Classroom. http://www.cfaitc.org/lessonplans/pdf/408.pdf This lesson provides
information on how selective breeding, genetic engineering, and better farming
practices have improved the tomato industry. Since the information is provided for by a
Agriculture Foundation, the educator should also include additional research
possibilities to bring in other sources of information.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice
Students are given a variety of possible
ways to share the information found in the texts provided. A suggestion would be to add
additional reference material that is from another site. This could add an additional layer
for the learner to check for any possible bias depending on the source of the text.
http://www.pbs.org/wgbh/harvest/engineer/ this url is a PBS interactive that compares
selective breeding with transgenic methods for a variety of crops,
http://learn.genetics.utah.edu/content/science/gmfoods/ another site that gives pros and
cons with genetically modified tomatoes. Educator can use these sites as well as
allowing the learner to do research themselves. The extension section gives many ideas
to include all areas of this practice.
This resource is explicitly designed to build towards this disciplinary core idea.
Comments about Including the Disciplinary Core Idea
Shows impact of humans on tomato
production, including selective breeding, genetic engineering, and farming practices.
This resource was not designed to build towards this crosscutting concept, but can be used to build towards it using the suggestions provided below.
Comments about Including the Crosscutting Concept
The lesson does not involve using
probability in the main part of the lesson. The extension section does include ways to
include a quantitative activity. It would be a good review of genetic probability to have
students do Punnett Squares to show the result of a tomato cross-matches..
