Sally McClure 08:06 AM I would like to receive credit for this professional development. Will there be a certificate or email for credit? Lauren Millang 08:07 AM https://www.onthefarmstem.com//about/credit-opportunities Brian Beierle 08:07 AM Hi Sally - there will be a PD certicficate. When the event is done we will confirm our registrants and work with Cornell University to get those out Karen Van De Walle 08:33 AM Do you find push back from kids with out ag knowledge? For example, I don’t know why they are different. I understand that it is meant to be totally introductory, but how do you get them over the hurdle of I don’t want to be wrong? Brian Beierle 08:35 AM That is a great question and it takes quite a bit of culture building around this pedagogy. We have an e-learning course on that culture that has multiple tips and resources to set the tone for instruction. https://www.onthefarmstem.com/curriculum/storylines Anita DeWeese 08:49 AM Are there options for virtual field trips that can be used in class for these lessons? Brian Beierle 08:53 AM Hi Anita! That is a great idea. We are in discussion of how to support teachers given the constraints of the pandemic. We have discussed this and it is under consideration. Check back in at https://www.onthefarmstem.com/ as we roll out other resources Jennifer Grivins 08:38 AM Do you have lessons set up in the best way that we can conduct this unit online? In Michigan we will either be in a hybrid in September (see kids 2 days a week 3 day online asynchronous) or entirely online. Can we share ideas and resources about that somehow? Brian Beierle 08:43 AM We are working on bringing more blended/virtual experiences to the units as we speak to make this as distance-learning friendly as possible. Also, we will establish a network of professionals around these materials in which professionals can share their experiences, questions, insights, tips, etc.. Rick will share that toward the end of the presentation Stacy DeVeau 08:52 AM Will these Ppts be made available to participants, preferably w/notes? Amelia Hayden 09:02 AM Yes, all guest speaker slide decks will be available after the livestream event. Charlotte Dyer 09:01 AM Are genetics able to be improved by consistent high quality environment, thereby changing the natural selection? Matthew Spangler 09:15 AM No. A consistently high quality environment could change phenotype, but could actually let “sub par” genetics thrive because the environment makes up for having poor genetics. If the environment is very challenging, then overtime natural selection could create animals that are genetically more fit or thrive in a harsh envrionment. However, natural selection takes a very long time. Leslie Carloss 08:18 AM Is their an agenda available for today's session? Brian Beierle 08:20 AM Here is a high level: 1. Context within NGSS 2. Experience the Anchoring Phenomena 3. Guest Speaker #1 4. MAking sense and setting up an investigation 5. Guest speaker #2 6. Reflect 7. Guest speaker #3 8. Navigation Routines 9. Extra resources 10. Wrap up Laura Miller 08:38 AM Do these Google Slides/Presentations work in various Learning Management Systems like Schoology or Canvas? Brian Beierle 08:42 AM That is a good question and I am not 100% sure I know the answer. However, we will convert our slidedeck to PPT and that should be pretty universal. The curricular materials are all established through Google Drive and could be converted as needed to Office apps if you are unable to run with the Google platform Jessica Radovich 09:08 AM Do producers generally try to improve the genetics of their stock themselves or are there regulations that leave that up to specific breeders? Matthew Spangler 09:20 AM They generally try to imporve them themselves. These improvements are often designed to improve profitability. Anita DeWeese 09:10 AM Do you have career connections to go along with this lesson? That highlights possible careers that would use this. Brian Beierle 09:25 AM The American Farm Bureau Foundation for Agriculture has some resources that might be yuseful: https://www.agfoundation.org/ag-lit-catalog/view/agriculture-career-race https://www.agday.org/careers-in-agriculture https://www.onthefarmstem.com/resources https://www.agfoundation.org/news/ag-career-lessons-and-more Hope these help! Brian Beierle 09:41 AM This could be useful too: https://agexplorer.com/ Joyce Dixon 08:51 AM Will this powerpoint be available? Amelia Hayden 09:02 AM Yes, all guest speaker slide decks will be available after the livestream event. Kay Benitez 08:51 AM can all breeds of cattle be interbred? are there any genetic barriers to interbreeding? Alison Van Eenennaam 08:52 AM yes they can all interbreed as they are all one species - Bos taurus - Susan Bender 09:11 AM do individula farmers perform these calculations on their own animals Matthew Spangler 09:17 AM Not generally. Most are done by cenrtailized organizations. Sam Northey 09:21 AM Are we keeping genetic material from Heritage breeds to pull the wild type DNA back in to the mix. Matthew Spangler 09:28 AM There is a repository of DNA from mulitple breeds across multiple agricultural specie mainatined by ARS. Ann Glowacki 09:28 AM Does the Belgian Blue's meat taste good with all the additional muscling they possess? Matthew Spangler 09:32 AM Taste is likely dependant on the person eating it (i.e., people have different ideas of what tastes good). It will be leaner (less fat). Interestingly, the mutation that causes this double muscling also creates tender meat. Surendra Surujdeo-Maharaj 10:00 AM Are any of these characters governed by non-mendelian inheritance? Matthew Spangler 10:09 AM Yes. Some coat colors come about through incomplete dominance or co-dominance. There are many polygenic traits (most traits selected for are polygenic). Some traits are sex-linked. Epistasis also impacts some traits. Angela Shaver 08:23 AM Is this session being recorded so that we can access it after today? You would like to answer this question live. Brian Beierle 08:25 AM YEs it is! We will post to the website shortly after. We also be taking segments of today’s events and creating supplementary video clips that could be used with students. Jessica Radovich 08:38 AM Why would horns be useful to humans? Alison Van Eenennaam 08:48 AM Horns are typically removed physically as they are dangerous to human handlers and other cattle - I will discuss this in my session - Alison Van Eenennaam Audra Leach 08:59 AM Is this presentation available to download as well? Amelia Hayden 09:02 AM Yes, all guest speaker slide decks will be available after the livestream event. Shiella Merriman-Parr 09:03 AM What environmental conditions can affect fertility? Matthew Spangler 09:17 AM Multiple conditions. The amount and quality of feed, the temeprature and humidity. There are also many that we do not know of or have not quantified. Zeta Greene 09:18 AM Are there traits that we as humans will not be able to improve on? Is there a cap? Matthew Spangler 09:21 AM If a trait can be measured, and it is heritable, it can be changed/improved. Some traits are harder to measure than others. In terms of improvement for a given trait, there are biological and economic limits. Gigette Webb 10:39 AM Why does the FDA classify gene editing as a drug? Alison Van Eenennaam 10:47 AM Really hard to explain! Not a position that makes a lot of sense. They argue that genetic alterations are intended to alter the form or function of an animal and so they are a drug. I argue that is DNA variation is a drug then we are all high!!! Deborah Green 08:14 AM Do you have suggestions for how to make Ag/gardening work via online instructon? Brian Beierle 08:18 AM We are working on addressing virtual activities to address the high likelihood of distance learning in this coming year. We will share out soon what we have created. You may also want to check out some resources available therough the Ag Foundation called Purple Plow: https://www.purpleplow.org/ We do have some garden-related “puzzler” that might interesting/helpful. Karen Van De Walle 08:37 AM How is this the first time I have heard of on the farm stem? It this relatively new? Brian Beierle 08:38 AM Somewhat…we have been doing immersive on the farm STEM events for about 4 or 5 years. This is our first step into providing NGSS-aligned and (hopefully) badged materials in an open education resource space Sally McClure 08:49 AM https://docs.google.com/document/d/1bZnve902eJQLMgAFzZTsGVkk6AUl6SI-a4VW -sGlfS8/edit Amelia Hayden 08:59 AM The hyperlinks are working on my end. Try right-clicking an icon and then selecting "Open Link" Sally McClure 08:51 AM The teacher guides, lesson presentation, etc. do not have links You 08:55 AM Do you mean the Genetics unit linked from here? https://www.onthefarmstem.com/curriculum/genetics Susan Bender 09:06 AM How are the numbers in the table derived? Matthew Spangler 09:18 AM They are derived using a set of statiscal models called the MIxed Model Equations. These equations parse genetic and environmental differences. They utilize kinship, recorded traits, and now DNA (genomic) information. Kathy Kleen 09:44 AM How do you make the changing world cloud? What app? Lauren Millang 09:46 AM It is a feature on www.menti.com! Kaylie Hieb 09:46 AM Does menti provide all they cool features that we are seeing throughout the presentation today? Would be super neat for students to use in the classroom (or online). Amelia Hayden 09:59 AM Yes. Menti offers a free account (there is an audience limit with the free version) that has these same features that you could use in your classroom or an online setting. You can find more information at www.mentimeter.com. Surendra Surujdeo-Maharaj 10:02 AM Is Genetic change the same as genetic gain? Matthew Spangler 10:06 AM Private answer Yes. Shiella Merriman-Parr 10:05 AM Will genetic interval be impacted by environmental conditions when breeding for specific genetic variations? Matthew Spangler 10:57 AM Generation interval is the average age of the parents when the next generation is born. It is possible this could be extended if the environment does not support animals reproducing at younger ages. David Thesenga 10:06 AM Whats the general lifespan of cattle? Granted there is a lot of variability - natural and created - but on average? Matthew Spangler 10:11 AM Private answer A crude range would be 6-20 years. Anita DeWeese 10:09 AM So this is why ranchers save their best females for herd replacements to keep those good genes in their herd and then they get a good sire to breed them to? Matthew Spangler 10:43 AM That is correct. The goal is to select the “best” possible parents for the next generation where “best” is conditional on the producers objectives/goals. Tiska Rodgers 10:11 AM Is breeding preferable to GMO's or do you use a combination such as inserting a "desired" gene and then breeding to proliferate the change into the population? Matthew Spangler 10:38 AM It would be a combination of tools and methods. Most traits are polygenic. So editing only one locus leaves a lot of other loci to be changed through breeding. Traditional breeding also helps proliferate the edit through the population. Darcy Soard 10:12 AM will the "editing" video be available to show our students? Alison Van Eenennaam 10:48 AM https://youtu.be/C0MBl0BANHg Leslie Carloss 10:16 AM The Belgian Blue musculature was completely natural?! Matthew Spangler 10:25 AM Yes. An animals muscularlity is part due to genetics and part due to environment (e.g., feed). The Belgian Blue’s genetic mutation for muscle has a very large effect. Susan Bender 10:17 AM Is the TB in cattle directly transmissible to humans Alison Van Eenennaam 11:07 AM Bovine TB is a disease caused by a specific type (species) of bacteria called M. bovis. Bovine TB usually affects animals such as cattle, but it can affect practically all mammals causing a general state of illness, coughing and eventual death. It can be transmitted from animals to humans as well as to other animals. M. bovis is a different type of bacteria to the bacteria M. tuberculosis, that is the type that usually causes disease in humans. The name Tuberculosis comes from the nodules, called ‘tubercles’ which form in the lymph nodes of affected animals. Anonymous Attendee 10:17 AM Is there a gene that can be edited to help prevent Trich? Alison Van Eenennaam 11:08 AM Not that I know of. That is part of the difficulty of editing - you need to know what gene to edit Lacie Fair 10:25 AM Are there any concrens about creating monocultures in the dairy or beef industry, or do all the breeds really help mitigate that concern. Matthew Spangler 10:35 AM This is a concern, however there are a few things that mitigate this concern. 1) all the breeds available. Crossing breeds helps avoid this. 2) There is still a lot of diversity within a breed. 3) Differnet objectives by different producers helps maintain diversity within a breed. Mutations also create new sources of diversity overtime. Mindy Kain 08:17 AM For planning purposes - what is the time frame for this PD? Thank you! Lauren Millang 08:17 AM Hi Mindy! We expect to wrap up around 1:30 CST. Leslie Carloss 08:32 AM I don't see where the PPT is on the website? Lauren Millang 08:34 AM It is on the home page- there should be a button that says “Download ppt.”! I hope this helps! www.onthefarmstem.com Lisa Gundy 08:35 AM I was unable to get Jamboard on my chromebook. I contacted our technology person and she is going to look into it this week. Is Jamboard generally user friendly? You 08:36 AM Do you have a Google Account? Chromebook should be very Google friendly :-) Google makes the Chromebook Brian Beierle 08:36 AM Generally yes. It is also a Drive app so it is easy to integrate in Google Classroom. You 08:40 AM There’s a chance that the Jamboard service has been disabled from within the Gsuite group. Is your Google account part of a group (school account)? Surendra Surujdeo-Maharaj 08:37 AM When did cattle first enter the human food chain? Matthew Spangler 09:27 AM Formally I suppose you could say around the time of domestication. However even before that the Aurochs would have likely been hunted. Kim OByrne 08:42 AM How long should you allow students to answer questions? Online is much different. Brian Beierle 09:34 AM Hi Kim! This is a good question and I am not sure there is a right or wrong answer. One thing that could be leveraged in distance learning might be to allow extra time to answer/generate questions by using virtual corkboards/whiteboards that could be kept live for quite some time between lessons which might be helpful for those students that appreciate the extra time. Audra Leach 09:02 AM Is this field experts ppt available for download? Lauren Millang 09:04 AM Yes, we will have the presentations available after the event. David Thesenga 09:14 AM Why a hump though? I understand it’s purpose in general. Is it a hump because of the heat loss aspect? Or is there another reason? Matthew Spangler 09:26 AM The hump does have increased blood vessels, so from that perspective it can help with heat loss. However, the muscle and enlarged vetabrae suggest it orginitaed for another reason. They tend to be larger in males as well. Aileen Ramos 09:19 AM whats the menti code again? Lauren Millang 09:19 AM 281147! Alston Brown 09:23 AM How long does it take to teach one of these storylines? Brian Beierle 09:27 AM This unit is 16 lessons long. Length of each lesson can be adjusted to meet your class requirements. Storyline approach will take a bit longer than a traditional lecture style unit, but the payoff of increased student ownership is worth the investment (IMO) Dylan 09:26 AM I can't figure out how to answer. It's not the fact that they have a hump, it's what's in the hump that helps tolerate heat and sparse food conditions. Matthew Spangler 09:36 AM Private answer The hump orginated from natural selection. The blood vessles in the hump do help with heat tolerance. The enlarged muscles and vertabrae might have orginated because this gave them a competitive advanatge overtime as well before domestication. Since domestication, some producers have likely selected for humps of a particular size and shape because that’s how they think a breed should look. Charlotte Dyer 09:28 AM The Human and Cattle Connection slide - is the Products Made from Cattle picture available on your website? Excellent for our Farm to Plate class! Brian Beierle 09:31 AM Hi Charlotte - it is currently just on the slides for the lesson found within the unit, which we will give copy/paste permissions to those who access soon. Copy/paste is currently disabled, but we will adjust that by the end of the week. We are also exploring elements within the units that could make for good stand alones…adding this one to the list. Anonymous Attendee 09:30 AM Could these lessons be cotaught with an ag teacher? Brian Beierle 09:31 AM Absolutely! We think that is a great idea! Susan Bender 09:30 AM how would you do the hand up stand up virtually Brian Beierle 09:32 AM Hi Susan - that is a good question. I think I’d give Zoom a try. Maybe use the “virtual” hand up feature and make use of small-group breakout rooms. You could also use an app like Pear Deck with the slides to increase the interactivity in a distance learning setting. Teralynn Flink 09:37 AM I cant respond in the chat You 09:30 AM Private answer How can I help? Sally McClure 09:39 AM Do kids apply the Blue question to people? How can we make people super muscular like that? Alison Van Eenennaam 10:52 AM In fact one biohacker did this!!!! https://www.theatlantic.com/science/archive/2018/02/biohacking-stunts- crispr/553511/ Lacie Fair 09:41 AM Rick Mentions a learning log or journal... is this available for students in a worksheet fashion or would this be more like a lab notebook for students just to keep track of their individual work? Amelia Hayden 09:50 AM Yes, in each lesson folder (found here: https://www.onthefarmstem.com/curriculum/genetics), there is a Student Learning Log google document that you can share either electronically or as a printed version with students. Deborah Green 10:16 AM Does the increased production of muscle (meat) have a negative effect on the skeletal system's ability to support all that muscle? Matthew Spangler 10:19 AM It could. Several specie (beef cattle, dairy cattle, poultry, and swine) have produced selection criterion for feet and legs structure to help ensure that genetic changes in structure support genetic changes for other traits. Well-practiced selection focuses on multiple traits at the same time. Angela Heitmann 10:26 AM Is there any data, short or long term, on how these edited genes have affected humans, in any way? Alison Van Eenennaam 10:56 AM Not sure what you mean - there is a patient that was cured of sickle cell using editing - just celebrated one year of being free of disease https://www.advancedsciencenews.com/the-first-crispr-gene-therapy-to- cure-sickle-cell-disease/ If you are talking about edited genes in cattle affecting humans - there are no edited cattle in commercial on the market Surendra Surujdeo-Maharaj 10:28 AM Please also post link to the movie Amelia Hayden 10:36 AM https://www.foodevolutionmovie.com/ Jessica Freidenstine 10:29 AM Could the links for the extra events be shared in the Chat and or Q&A? Amelia Hayden 10:38 AM https://www.genomewritersguild.org/ask-a-sci-registration-2020 Leslie Carloss 10:40 AM What was the name of the disease she mentioned? Matthew Spangler 10:42 AM The disease in pigs was Porcine Reproductive and Respiratory Syndrome. Sally McClure 10:50 AM Dr. Eenenaam, As a geneticist, what made you interested in animal production?
