PLN #3- NASA and Homeland Security Test Radar for Locating Disaster Victims

The article “NASA and Homeland Security Test Radar for Locating Disaster Victims” by NASA is about new technology that will be used to help locate people from debris and wreckage after a disaster. This past Wednesday, September 25th, a new use of radar technology was demonstrated. NASA has created a device known as “FINDER”, or Finding Individuals for Disaster and Emergency Response, is a portable device with the purpose of assisting disaster response teams in locating disaster victims trapped or lost after events such as earthquakes, tornadoes, hurricanes, etc. This device was tested to locate victims trapped under 30 feet of rubble, and can detect their movement through 20 feet of solid concrete. The scientists at NASA share how this works by sending out microwave signals, then decoding the signal received as the microwaves bounce off of objects in their path. FINDER would help for the disaster and emergency response teams to locate victims easier, “allowing rescue workers to more precisely deploy their limited resources,” as quoted by John Price, manager for a First Responders science and technology group in Washington. The article then goes on to tell how this technology may be seen in the near future, such as to monitor the vital signs of astronauts. In conclusion, this new technology can be expected in the near future to aid First responders in locating disaster victims, or later in the future of space travel and astronomy.



The article “NASA and Homeland Security Test Radar for Locating Disaster Victims” by NASA made me feel hopeful because with this tool, more lives will be saved after large scale disasters occur. After large disasters, such as a hurricane, earthquake, or even a bombing, I believe it is crucial to locate and rescue the trapped people as soon as possible. I think that during that time, dehydration, starvation, or life threatening wounds could cause death to the victim if they remain trapped for too long. I am excited because this device will help to solve the problem of not knowing where to look for victims in an area affected by a disaster. Because of the algorithms used to decode the microwaves used by FINDER, search and rescue teams would know exactly where they need to find the person, making the overall rescue go much smoother and faster. This saved time may make the difference for some victims, who may have been injured in the collapse of a building, or by whatever means they are trapped. I am very optimistic about FINDER because it has been recently demonstrated, showing that the technology does exist now and can be put into use very soon. This device could be seen saving lives very soon in the future, in those valuable seconds after a large scale disaster erupts. I value the importance of this device, because it’s pretty cool that science has come up with ways to start saving the lives of people TODAY. Overall, I think this is a very cool invention, and it gives me a lot of hope for the future of science and humanitarian efforts.

  1. Your topic for your PLN was really cool! I like how you made notecards and didnt just read off of the screen. You are confident when you speak and you make eye contact. Your summary was really great, there was no "I" and it contained a lot of facts. Your response was good too because you put some of your opinions in the mix of facts. Great job!

  3. The writing was very good i did not see anything that was not correct or did not make sense.

    The speaking was good not to fast not to slow

    This sounds like a very cool invention the only problem is that it is probably quite expensive.

  4. Your speaking was very clean, you only said 'um' a few time which is unavoidable when speaking in front of your peers. I think the idea of this machine is very helpful and only if it could've been used back in 911 to save a few lives that were stuck in the wreckage. The length of the both the summary and response were perfect and the information given seemed the fit the criteria for both the summary and response. Good Job :]

  5. I think your speaking was pretty solid for the most part but there were a couple spots where you paused and seemed unsure. You were confident in your speaking for the most part and had a good delivery. As for the writing, it was just as good as the speaking. It was intriguing and just really cool. I think this technology will be very useful in the future and save many lives.

  6. I love your topic Gretchen! I have heard reports of devices like this being used in the Colorado Floods. You had a few ums and ers every now and again but your speach was solid. It seems that you also practiced your presentation as well because you knew most of the content. I think overall, you did a really nice job since, as you stated, this is in use today or in the near future.

  7. I think that was really great. you looked at the crowd instead of the page and yo knew what you were talking about. i think the only thing is that at the beginning of the summary you said it was a really cool article, i don't know if you did that before you started or what but try not to use opinion in summary. that was the only thing though, you did a really really good job.

  8. Your speaking was good. I could understand you really well and could tell that there were a lot of feelings towards this article.

    Writing- The summary and response is at a good length and you use a lot of description.

    I too have hope for this new device. I think it be helpful to all of the injured victims that need help.

  9. You did very well when you were speaking because I could tell that you knew a lot about the article. Next time I would try and stand still a little bit more and don't say "um" as much. Other that you did great.

    Both your paragraphs are great. I liked how in your summary paragraph you put a lot of details about the article.

    I think this tool will defiantly be helpful in the future. I think it is cool that when they tested it that it was sucessful

  10. I think you did a really good job! You used really good word choice too and you seemed to really know what you were talking about and you were very passionate about the topic. I also agree with you and I think that's really cool how people can be found in that way. At the beginning there was a lot of facts thrown out that made it a little hard to follow but other than that very good job!!

  11. I think you did a great job talking to the class! You were very passionate about it and I could definitely tell. The only thing I would say about your speaking is don't move around so much. You did tend to rock back and fourth, but other then that I would say you did a great job and you writing was again amazing as always!

  12. Your speaking was great! You are a natural speaker! You weren't to powerful but you weren't to ruthless either. You didn't look at the screen to much which was also good.

    Your writing was very powerful. you used strong verbs and not the boring ones. You didn't repeat yourself very much either in your writing.

    I like how you said it gives you hope for the future. I never thought NASA would be able to do that. You seem like you really care about the environment and other people's lives.

  13. The article that you talked about by NASA really does give hope for rescuing people in the future. The things you said about how this makes you feel hopeful really got why you say it makes you feel that way. This was a great article to chose and you really got the point of this new tech across. Also you spoke very well.

  14. Your speaking was really good. Towards the end, you kept looking up at the screen.
    Your writing was good, but maybe a bit long. Good using quotes from the article.
    I feel like this is a cool invention. I think that it will be very useful when the next natural disaster strikes. And I think that it will save many more lives of people.

  15. Great job! You did quite well speaking and rarely used filler words, though you did trail off in your speech sometimes. You fidgeted quite a lot. If you work on that I believe you'd really improve. I agree that this is a great thing!

  16. Your speaking was all around good. A few times you fidgeted and seemed nervous, but you were one of the first people to present, and so I congratulate you for keeping so calm.

    The writing was well formatted and an all around interesting subject. During the response you seemed to open up more which was good.

    I also find this development to be one hopeful to what the future technology can do to save lives.

  17. While you spoke you did say "um" and "like" a few times. Other than that you did a really good job at conveying your opinions and telling us what was in the article.

    Your writing was well formatted and seemed to cover all of your points. I would like to know more on how it was tested and how they are planning to improve it.

    I think its great that they are coming up with more was to find people and save them. I can't wait the see what happens in the future with this invention.

  18. Bring your speech I thought you did really good by having a loud voice and you weren't really saying uhm that much or other things that might make a group off track

    I thought that your article was very cool. I would love to read it for my self. One of your facts that it was used last week was really cool to think it could be in are world very soon!

  19. Overall, I think I did pretty good presenting. I was able to keep eye contact, and only lost my place once or twice. I should work on using less filler words, as I found my self saying "like" a few times.
    I think my summary fully holds all of the main ideas for the topic. I could maybe even add more detail and research to support these ideas.
    I think my response could use more detail to support my opinion of why I think that this technology is cool, and more emotion about if I like or dislike the new technology.

  20. I really enjoyed how comfortable you at least looked while you were presenting for everyone to see. I liked how in your response paragraph you included serious things that could happen and when you would need the fancy device. If the world was coming to an end and I saw someone dying i honestly have a cold enough heart to leave them there but if I had the fancy device that you speak of then I know I could easily save a life. Your paragraphs were easy to read and understand and the topic isn't boring and bland. Overall your paragraphs are very good. Nice job Gretchen

  21. This presentation was the best one i have seen in why two years of English 9. You did not use words like "like" or "um". Good job looking at the class and not just staring at the the screen. I agree with what you were saying because this tool will be very helpful for disasters in the future not just in the united states but world wide. Overall great presentation

  22. I think you did a really good job! Your summary had lots of information, was easy to follow, and you seemed like you knew the topic well!


    In your response, I feel like you could have had a little more emotion put into it. But overall, I think that you did a great job!

  23. Gretchen, that was amazing!!!

    Your speaking was fantastic, but the only thing I would have changed was how much you moved around. That got a little distracting. But I'd give you a thumbs up!

    The writing was spectacular as well! You are so smart and it really showed in your writing. I don't think I would have changed anything. Another thumbs up! (:

    This article made me think a little. Its odd how it took so long to get our technology up to date. But, its good that we did get there.

  24. When you were speaking you were messing with your flash cards a lot, which was distracting. Also you said "Um" a lot, you should try working on that. You spoke loud enough for me to hear you, and I sit in the back. So, that's a plus. Overall your writing was awesome, but you repeated that the tool makes you feel hopeful, I would try not repeating yourself. And the article you picked was pretty good, so good pick.

  25. You did a very good job with eye contact and volume control. It looked like you felt very strongly about this.

    Your writing was very well written.

    I agree with you, this will be out there someday saving lives, changing lives.

  26. Great job Gretchen. Your specking was clear and your word choice was great. At times you did lose your spot on the screen but over all you had a great presentation.

    I love the article you have chosen. I think that would be awesome to have a device that can save people from a disaster. Also it would make country's heal quicker from a disaster.

  27. Speaking: You did a great job! You looked very comfortable up there and kept me interested. You said "um" a couple of times and rocked back and forth a little bit but other than that you were very smooth.

    Writing: I liked your writing it was very in depth and had a lot of details. Maybe next time add a little more opinion into your response? Other than that minor tweak I think both paragraphs were easy to follow, complete in coverage, and over all very good writing.

    Response: I agree with you! This technology will help us save more people and create more heros. When natural disasters strike at least now with this improved technology we wont be as devastated.
