I’m Joseph and I will be talking to you this week about planets, stars and the search for life. Looking forward to hearing your questions and opinions during the week Silvia Rapp Hello Joseph! My name is Silvia and I am from Germany. I am looking foreward to the live session tonight and I hope for an interesting discussion. Joseph Roche Thanks Silvia - I hope you enjoyed the live session tonight! Astrobiology Viki Majer Hello everyone I’m a geologist and very intersted to this topic. Are we alone? Planetary systems outside our are like distant cities whose lights we can see twinkling, but whose streets we can’t walk. Can we learn how stars and planets interact to form their own ecosystem? Thak you. Joseph Roche I hope we can answer some of those questions in the future. And the geologists will be key to finding those answers! Astrobiology and evolution Aynur Elif Bulut Hi, i am Aynurelif from Turkey. I am a biology teacher at Ankara Science High School. My students really wonder about other universe and the expansion universe. So, i have attended this topic because i would like to explain them correctly. Joseph Roche Hi Aynurelif, thanks for taking part! If you are looking for a quick answer for your students then you could do worse then point them in the direction of this short video by Bill Nye in a debate where he was asked to explain the expanding universe: Bill Nye explains the expanding universe Biology and Chemistry Viki Majer Joseph Roche Life is unique so wonderfully walkthroug even at the cellular level so amazing , and this whole effort only for the life forms on Earth . I just can not believe that this blueprint was applied only once Agreed. We are probably not that special :) Biosphere 2 experiment Fatma Bilir Hi Joseph, I am a biyology teacher in high school. My students and also I wonder about Biosphere 2 experiment. What do you think about this experiment ? Do you think If this experiment had been successful, did another biosphere can be created in space ? Fatma BİLİR Biology Teacher Turkey Joseph Roche Hi Fatma, Thank you for your question. I think Biosphere 2 is a fascinating experiment. I very much appreciate the ideas behind it and I am very glad to see that it was not demolished and continues to yield scientific results at some level. But I also think the implementation of the original experiment might have been handled a little better. It captured the public imagination at the time but perhaps was not as transparent as it could have been about the successes and failures of the experiment. As it was such a challenging undertaking it was always likely to face elements of failure and I think the researchers involved could have shared their opinion on what was going wrong more publicly rather than it being kept a little bit quiet until later in the endeavour. With public-facing experiments like Biosphere 2, I think scientists have a responsibility to inform the public how likely they are to fail with their efforts and to reveal when that happens. Failure is just another stepping stone towards scientific progress and is something that should be embraced by scientists and educators so that students and the public alike stop thinking of failure as such a negative outcome. What we have learned from the experiment is that biospheres in general are extremely difficult to sustain and I think it will be a long time before we see one in space. Joseph. Biosphere 2 experiment Fatma Bilir Hi Joseph, This valuable informations are very important for us. Thank you so much :) Fatma. Joseph Roche Happy to help ;) In the classroom - can we talk about life elsewhere in the universe? Joseph Roche Hello All! Thank you for your questions and comments so far. Today I would like to pose the question: “In the classroom - can we talk about life elsewhere in the universe?” Is it acceptable for us to bring up the hunt for extraterrestrial life with our students? Some educators feel that even broaching that area has too much uncertainty to make it appropriate to discuss it in class. Could support from scientists and universities and research institutions help to break down the barriers to discussing astrobiology with young adults? Do conversations about “aliens” just get completely hijacked by stereotypes and perceptions generated by science fiction? I would love to hear about your experiences engaging with this question in the classroom environment. Joseph. Gabriella Baron Hi Joseph, I’am a geologist and I theach in a middle school math and science. My students are found of astronomy and when studing the solar sistem, our galaxy and the universe Always ask me: may be another planet like Earth? Are we so unique? May be worlds where the organic substances can evolve into life forms? Their curiosity leads them to ask question and look for hypotheses to explain how this could have happened. Thank you. Gabriella In the classroom - can we talk about life elsewhere in the universe? Nihal Yıldırım Hi Joseph, Our first subject at 9th grade is the components of creatures.I ask student some students to discuss this issue. Is there similar features between living and dead creatures? Oxygen, hydrogen, carbon elements that exist in the structure of living creatures also in inanimate have? Can living things continue life without oxygen? Can we survive another planet? Students discuss these questions. Could there be life on another planet? İf there was atmosfere on mars could we live there? The students ask these question. Thus we can disscuss the subject of living at different planets with curiuos students. They think only life on the Milky Way galaxy. The possibility of the idea that a life on another galaxy make them skeptical and it reflects on their faces. I wonder if there is Life on the other galaxies ? Thank you Nihal Yıldırım Joseph Roche Hi Gabriella, thanks for your comments. I am happy to hear that your students have such good questions - especially “are we so unique”? I think it is a good sign when you young people consider the importance of our species. I’m even happier to hear that they use these questions as a way to develop hypotheses to explain how life might evolve elsewhere! That makes me excited about that future :) In the classroom - can we talk about life elsewhere in the universe? Joseph Roche Catherine Zörner Hi Nihal. I think that is a very good idea to look at the world around us and what we do understand in order to postulate about what we do not understand. Getting the students to think about the similarities between living and dead creatures on Earth would help provide a framework for how to consider defining life on other planets. There are likely billions of other planets in our galaxy alone, so thinking about the possibility of life in other galaxies too is staggering :) Hi! My name is Catherine Zoerner, and I am training to become a Biology and English teacher in Austria. I had the pleasure of listening and following your very interesting webinar and I was suprised how many thoughts and questions it awoke in me. Astrobiology is unfortunately not given a lot of attention in the teaching curriculum, however I have tutored and helped some students to prepare for their A-levels in Biology and almost each one of them chose to specialise in astrobiology. Time travelling, planets, life somewhere else and outer space in general, have alsways fascinated humans, which is represented in the last movies, such as “Interstellar”, “The Martian” and “Gravity”. Children enjoy watching these movies and therefore, astrobiology is given a lot of attention. There is an incredible hunger for information when it comes to the possibility of life somewhere in the universe. I have found, that students are blown away when you tell them how small our planet is, that it is part of the Milky Way and what else is “out there”. As you have mentioned in your webinar, it is almost healthy for the pupils, to realize that we are not the centre of the universe and that there might be life somewhere else. They mind is broadened and they let themselves be shown another level of perspective, which is a wonderful thing. I believe, that when using the term “aliens” the children do tend to stick to the sterotypical images they have in their minds, however if you come from a different angle and tell them how life on Earth started, then they might start to break down their preconcieved opinions. When referring In the classroom - can we talk about life elsewhere in the universe? Catherine Zörner to life, the smallest living organisms are all it takes to call it “life on a different planet” This, of course is often a delicate topic, since religious beliefs and science do not agree on when “life began” on Earth. There is no doubt, that this is not the easiest topic to teach to children, however it is incredibly interesting and should be given some attention and time in the classroom. I am very sure, that the pupils would enjoy learning about this field of studies. Catherine Zörner Roberta Morrone Hello, I’m Roberta Morrone, and I’m an italian teacher. I’m sorry for my english! I talk about the Universe to my students (12 years) in this days. Theyr minds go quikly to other kind of life when I tell them that there are a lot of stars and other kind of star’s systems. But what kind of life! Not the same! They learn and understand the carapteristic unicity of our planet Terra. I like tell them step by step the study of the man and how he can keep and study and understand this big Universo and I like to see theire stupore and there eyes when they begin to think and propose questions. I tell you about this another days. After knowing Amgen and the IBSE metode I always try to use questions that begin with “how do you think ...”. See you later Roberta In the classroom - can we talk about life elsewhere in the universe? Elias Wojta Hello, Joseph, For me personally there is probably no other topic as exciting as life on other planets. It is also a topic most if not all children are very excited about, so discussing it in the classroom would be a good way to get them interested in the scientific field in general. The biggest problem in my opinion is the stigma that’s attached to “aliens” and even just the search for intelligent life. The existence of aliens is often equated to conspiracy theories like lizard people or skin walkers because a lot of people can’t handle what they don’t understand and ridicule it as a result. That however shouldn’t stop reasonable people from pursuing the topic and engaging young people to participate in the process. I hope we will hear more about this topic, Elias Wojta Joseph Roche Hi Elias, Thanks for your input and for highlighting the stigma that’s attached to “aliens” and the relationship to conspiracy theories. I felt myself that there are issues with the stereotypes but it is good to have that confirmed with evidence from the classroom. I think I will devise a research project at some point to address the misconceptions and stereotypes surrounding aliens and extraterrestrial life. Joseph. Joseph Roche Hi Catherine, Thank you for you thoughts on this. I think you raise some very important points about the challenges of stereotypical images of aliens and the science vs religious debate about when “life began” on Earth. I am really glad to hear that despite the challenges you feel this topic should be given attention and time in the classroom! Joseph. In the classroom - can we talk about life elsewhere in the universe? Joseph Roche Hello Roberta, Thank you for taking the time to share your opinions. I very much enjoyed reading them. I am especially pleased that you are confident about talking about the Universe and using questions that begin with “how do you think ...” :) Joseph. What are the benefits and challenges of STSPs? Joseph Roche Hello everyone! It was very nice to engage with you all last night in the live session and I hope I have given you something to think about in terms of “Astrobiology” and our quest to find life elsewhere in the universe. A significant portion of my talk last night focused on “Citizen Science” and my belief that over the years ahead we will be challenged to find ways of incorporating large-scale scientific projects into formal education systems. My question at the end of the session was: “What are the benefits and challenges of StudentTeacher-Scientist-Partnerships?” Over the coming days I think it would be interesting to gather opinions from you on this topic. Do you think engaging with active research would help empower your students to feel like scientists and give them confidence with the subject? Do you think it undermines the scientific process by having young people engage in a project early in their education? What kind of supports might be needed to implement an effective engagement? Do school visits by scientists actually help or are they merely a distraction? Whatever you think the benefits and challenges are I would love to hear your opinions. There are no right or wrong answers as this is an emerging area so feel free to say whatever you are thinking. Looking forward to some interesting discussions What are the benefits and challenges of STSPs? Aynur Elif Bulut Hi Joseph, I would like to say again that ‘Citizen Science’ is important to us who we are worried about our Earth... I agree with you. Therefore i tell my students how to prepare project. First of all i only tell that you should think simple if you want to solve a problem. Because if you think complex, you probably will be away from the goal. So, i only tell them that ‘think simple, solve quickly...’ Secondly, i would like to answer your question ‘What are the benefits and challenges of STSPs?’ The Benefits are; Students will expand their learning path. Teachers will become a leader who they learn with pupils. In this case it means fresh blood and different perspectives for scientists. For partnership, i am not sure which will be happened ‘benefit or challenges’. Finally, i always believe that inquiry-based education and project based education direct students to think. So,learning can only be achieved in this way. Have a good evening. Aynur Elif Joseph Roche Thank you Aynur Elif! I am glad to hear that Citizen Science is important to you. I agree with your points about STSPs expanding the learning of students and providing different perspectives for scientists. I also think you raise some valid points about inquiry-based and project-based education challenging students to think. I believe this is why Citizen Science will find a place within the formal education system. Thank you for your thoughts and I look forward to hearing more during the week. What are the benefits and challenges of STSPs? Nihal Yıldırım Hi Joseph, I am a biology teacher in high school. I teach my students scientific thinking. Because the scientific thinking of making sense of life is important. İt builds towards the cause of scientific thought and effect relationships. Reach a solution with the data in hand. İn science this process is important to the subject of the humanitarian approach. This state of mind supports the students thinking. Examines student event realistic apporach. Understant it might be supported by evidence. They can be seen as a benefit. Traditional thinking may conflict wiht scientific thinking. This may cause the student to think deeply. This can be seen as a loss. Joseph Roche Elias Wojta Thank you Nihal. I am very pleased to hear that you teach your students “scientific thinking” in a high school biology class. Students are often taught science as a body of knowledge, rather than as a way of thinking. I believe that the way of thinking is so much more important. We find at university level that it can take a while for the students to “think like scientists” even if they have acquired large amounts of scientific knowledge. The challenge of “traditional thinking” conflicting with “scientific thinking” is an interesting one. I had not thought of that as a barrier to STSPs but it is a very good point. I like the idea of the “humanitarian approach” being integral to the process. Thank you for sharing your thoughts :) Hi Joseph, First of all, thank you for the very interesting webinar, it was a great experience. In relation to your questions, I think including students in the scientific process is a great way to get them interested in pursuing a scientific career. I don’t think the scientific process would be undermined if young people are included, on the contrary I believe it’s important to have young people and students engage in research and the scientific process. That’s one of the only ways to get them excited about the process. Thank you again for your time What are the benefits and challenges of STSPs? Joseph Roche Hi Elias, Thanks for your thoughts. It is refreshing to hear that you think including students in the scientific process is a good way to get them interested in pursuing a scientific career. I will keep working and hopefully I can find evidence to support this work :) Joseph. In the classroom - can we talk about life elsewhere in the universe? Joseph Roche Dear All, It has been a pleasure engaging and interacting with you this week. I hope that it has led to some new ideas and fresh perspectives. If you would like to discuss any of the topics that have come up this week or you have any ideas or thoughts that you would like to share - then Twitter is probably the best place to continue the conversation. You can find me here: @joeboating You can also pose questions to the @eu_schoolnet handle or using the hashtag - #AmgenTeach. Thank again for all your insight and comments and best of luck with your future endeavours. Sincerely, Joseph. Aynur Elif Bulut Dear Joseph, Thank you so much again... It was interesting topic for me... Aynur Elif Joseph Roche Thank you for the questions - it was very interesting for me too :) Joseph Roche Dear Mr Roche, first I wanted to thank you for the great lecture! Here are my 2 questions: 1. How long will it take until mankind will have the technology which is necessarily to build new means of transport which can get to e.g. alpha centauri? or.. do you think that this is simply impossible for us humans? 2. how can you recognize an planet (within a sun system) in outer space which is in the right distance to its sun? (neither to far nor to near) In the classroom - can we talk about life elsewhere in the universe? Judit Makkos-Káldi Hallo Joseph, First of all, I would like to thank you for the interesting topic you were talking about recently. I have PhD in animal sciences, having 10-year-teaching experience in adult education, currently studying biology at a University College of Teacher Education, to be able to educate school pupils as well. Secondly, as for me, engaging – sustainably - both adults and students at the age 10-14 seems one of the most challenging issues for teachers. That is why I was happy about your input of “Student-Teacher-ScientistPartnerships“. Getting insight to scientific procedures, through scientific problem solving, students can learn that science is more than just learning boring facts and concepts. Of course, as a teacher, our responsibility is to find the right methods to involve and motivate our students for a certain topic, to get and keep them enthusiastic. I think, astrobiology, the hunt for life beyond Earth is indeed one of the most exciting topics for everybody disregarding the age, place of living, the profession, the religion and beliefs, etc., and disregarding the fact, how much somebody knows about the universe and its scientific background. Therefore, this area gives the teachers lots of opportunities to get their students inquiry-oriented. As inquiry-based learning starts by posing questions, problems or scenarios, rather than simply presenting facts and figures, teachers can use a wide range of methods to facilitate their students. Citizen Science is only one way for that. Young Citizen Science projects or events like the European Researchers´ Night give the opportunity to be part of the topic. If students can have the feeling they are part of the science, if they can not only see, but also experience, this will definitely expand they learning path. Finally, how to bring astrobiology into classrooms? Virtual planetary laboratory games, quizzes, and various demonstrations allow the increase the level of interactivity in classrooms. Students can and should use their imagination, keep on formulating questions and trying to find the answers by themselves, etc. Thank you once again! In the classroom - can we talk about life elsewhere in the universe? Joseph Roche Dear Amir, Thank you for your questions. They are very good questions and not so easy to answer :) (1). I would not like to say that it will always be impossible for us to travel to another star, but for the moment interstellar travels looks extremely unlikely for a long time to come. It probably will not be the technology that is the problem, but humans. It would be very difficult to transport humans such great distances for such long periods. Although concepts like “human hibernation” and “generation ships” would present ways to overcome this barrier, they look just as unlikely as interstellar travel itself at the moment. (2). Exoplanets are often discovered when they periodically orbit in front of a star. Although we cannot see the planet directly we can notice its presence from the dip in star brightness when the planet is in front of the star (similar to how the moon causes a dip in brightness from the sun when it comes between the sun and the earth during a Solar Eclipse). From these measurements we can estimate the period of orbit of the planet. We can then use Kepler’s Third Law to calculate the distance that the planet is from the star it is orbiting. It is explained better here: https:// www.sfu.ca/colloquium/PDC_Top/astrobiology/discoveringexoplanets/calculating-exoplanet-properties.html Joseph. Joseph Roche Hi Judit, Great to hear about your experiences and feelings towards the topic. I think your suggestions for bringing astrobiology into the classroom are excellent. “Virtual planetary laboratory games, quizzes, and demonstrations” are really good interactive means to engage a classroom. Thank you for sharing! Joseph.
