Binding Energy & Excel(l)ing at Graphs

Well, that’s it – you’ve finished your Extended Practical Investigation…

Almost.

You didn’t think it was over, did you? Really? That’s cute…

Well, you still have to demonstrate some level of reflection, communication and discussion about your findings. Part of learning to be a scientist is contributing to community discussions – discussing and improving the common practice.

You know how important it is to communicate scientific ideas clearly, and be able to respond to scientific information in reporting in a considered and appropriate (yet sceptical)Β  manner.

So, you are required (yes, this is a work requirement) to do the following tasks:

  1. Navigate to the Excel Tutorial on GraphingΒ and Advanced GraphingΒ and read them both. Provide proof of your understanding by creating and printing a graph in Excel (using a data set that you have or create), showing:
    • Trend lines
    • Error Bars
    • Regression Equations
    • And all appropriate labels.
  2. Place at least one comment and one response to another student’s comment discussing your experience of the EPI, what you learned, found out or would do differently, *OR* contribute to the Mind42 Collaborative Mindmap (to do this, you need to put your email address in a comment on this post)
  3. Finally, Binding Energy. Using the following two links (1, 2) to complete this worksheet.

A video for those of you who want more clarification on error bars (remember, you will need to do this in practicals from now on…)

For those of you who are interested in Physics, you may want to check out The Particle Adventure – it will give you an advanced understanding of the ideas behind our current detailed study.

And, that Ladies & Gentlemen of HPSC, is the final work requirement for Unit 1 – Congratulations to all who finish.

And to those who haven’t – you’d better get it done soon!

See you after the exams!

    The EPI was a shocker! A lot of confusion and doubt. But it was really good to test our knowledge in a practical way, in addition to the teamwork needed to make it ‘work’. I’ve learnt to use time more efficiently for our next EPI, as the writing up took longer than expected. Overall, goodwork to my team πŸ˜€

    • darrren10 Says:

      Yes making it on time was pretty impressive i guess.
      and yes, there was a lot of stressing coming from group members πŸ˜„
      i just wished we stressed out before the epi and been calm during it rather than what had happened πŸ˜„
      and i think we did pretty well, we got a result which is what counted though i think we should have researched graphing it a lot more than we did. and yes, well done team (Y)

  2. Paolo Says:

    The particle adventure link, will this provide further knowledge in preparation for the exam?

    Currently reading through the The Standard Model tabs

    • CyberChalky Says:

      Hi Paolo,

      No, the Particle Adventure will not specifically improve your Exam preparation. If you make the effort to integrate the knowledge, it may help develop understanding of why things like binding energy exist.

  3. darrren10 Says:

    Well when going into the EPI we had been warned it would be hard but i knew that the hardest part was going to be the last session we had as that’s when we were frantically having to write everything up. As expected it was as big a pain as we had thought it would be. The first session wasn’t too bad but then during the second session things started to turn just as murphy’s law states (anything that can go wrong will go wrong). But that was quickly finished. On completion we thought we had it but were quickly shut down as we were told it wasn’t platnium. However in our defence, the other metal we would have guessed would have been tin.

    • Rares Says:

      I agree with you statement:” anything that can go wrong will go wrong” well said Darren. Also yea true the first lesson was ok because we were all like ” oh we have 2 more don’t worry” but when the next lesson passed and we didnt start writing… that is when panic starts…

    • sahil26 Says:

      Hey! no problem … we had gold !! then silver, then copper.
      We figured copper was a more realistic answer.
      Common sense did it πŸ˜€ .Sometimes science just doest work O.o

      ( I m also aware that this comment is against the laws of Mr.G πŸ˜€ )

  4. Rares Says:

    The EPI was impossibly interesting. But i Kind of didn’t use my time right so…. We were warned but we didn’t listen. So we suffered. It was hard. We kind of didn’t know what to do when we put the circuit together. We stuffed it the first time. Then we got it right and in the end we barely had time to write everything up. When we had the weekend to study I used that time to fill up some info gaps. I know now what to do for the next one:D
    Peace out

    • Dylan Says:

      I agree with Rick, planning is the key, learning as much about the topic before you start is really important so that when you start you know what to do and you can get straight into it.

  5. Dylan Says:

    I too think more planning should of been done because on the first day the only thing we really knew how to do was measuring the pieces of metal, and that night i think everyone went home and had to look up how to do something, which isnt good becuase pretty much everything could have ben found out before the prac began.

    • Paolo Says:

      Agree with Dylan’s thoughts on planning ahead, it would have saved us valuable time and less stress on our teammates parts.

  6. Dinel Meyepa Says:

    Planning was probably the most important aspect of the EPI as it was needed to be done before and after each of the 3 lessons. Completing all of the questions at a high standard would have been close to impossible without gathering information before hand. Everything was planned prior to each lesson and I believe that this was what got us over the line. We also had to use the time we had effectively. We first had to set up the circuit and record all measurements. This would allow us to begin writing up the prac during the second lesson. The third lesson basically required us to gather the rest of the data & info and to complete the questions we hadn’t left time for. To improve results next time, I believe that each group member needs to be given a specific research task before hand so that everything is sorted out and organised.

    • Brendan Says:

      Your definetly right about that, planning, planning and more planning was what was required to successfully complete this task. Without it my group and many other groups came in on the first day thinking this will be a breeze, a bit of measuring, setting up a circuit, simple! But by the end of that session we were all in panic mode. By the next session we had frantically studied to work out everything we needed to do to get the results that we needed. Even though my groups and probably many other groups results weren’t correct we still figured out and followed the method required to complete this task, even if our results may have been a little bit off πŸ™‚

    • Troy Cardozo Says:

      I agree with Dinel Meyepa that Planning was probably the most important aspect of the EPI, because without planing i think its not even possible for a smart kid to do the EPI unless he has done it before πŸ˜›

      P.S If it wasn’t for the other post on how to solve resistivity and measure and more, i think we would all fail the EPI

      I also agree researching should we a most important aspect of EPI too, For eg if we dont know how to use a Multimeter, there is no possibly way we can pass the EpI thats why researching is very important too.

      Im done talking. πŸ˜€

      LATORZ.

  7. Ashraf Says:

    when going into the EPI we had been warned it would be hard, especialy when my team was like didnt know what to do at the 1st lesson of the experiment, but we mananged by discussing and putting ourself on more pressure.but it was good for us to test our knowlege to do it better in the future and i have learned to use the time more wisely for our next EPI.
    OVerall good work team πŸ™‚

  8. Ashraf Says:

    I agree with you Dinel that planning was the most important aspect of the EPI as it was needed to be done before and after each of the 3 lessons.
    Like if you are not prepared what you and your team mates are going to do and dont know what your and their responsibilty in the experiment is then i agues i say that team is stuffed. IF you can not gather the information reqiured then how u going to answer the qestion wit out the information that the team were suppose to gather during those 3 EPI lesson. πŸ™‚

  9. Levy Says:

    Hi sir. The EPI was hard for our group, because we didn’t think the write up was going to be that long. But i guess we just gotta learn from our mistakes and do a better job on the next EPI. πŸ˜€

  10. Brendan Says:

    The nightma- I mean EPI that we just completed, was as diabolical as we were told, yet we still somehow managed to pull through. Like many other people have said before planning and assigning jobs for everyone to do was essential to complete this task. By having someone working on onething, someone on another and someone writing down the results, each job was completed faster making our time collecting data shorter and our time for collating our data and writing our practical reports longer. I think that the most difficult things about this were probably time management and that bit at the end where we went “hey…aren’t those numbers meant to be the same?” When we next have to do another EPI I think that everyone will definetly be more prepared and will have fully realised how difficult that the task will be. In an EPI I definetly think that the keys to success are time managment and accuracy and my group and I will definetly keep this in mind in the future.

  11. Lovleen Says:

    EPI… to be honest, despite all the given warnings, I didn’t take it as seriously as I should have. Now that I look back at it, our planning was not that good (but before the EPI it felt like it was more than enough). And it sounded like we had a lot of time, 3 FULL lessons. but really, it was not. We also nearly blew the multimeter at the start… and the measuring equipment not working properly didn’t help us either. It wasted like our whole lesson. But, now I know that EPI is actually something which should be planned (properly), and the rest should be a piece of cake

    • Paktia Says:

      Yeah we were like that too, we were given all the warnings but took it as a bit of a joke, and found out, it was actually as hard as we were told it would be, I thought the time we were given would be enough, but throughout the EPI, everytime I checked the time, it was flying x). More preparation was neccesary for this EPI <:

    • Zaki Zulkafli Says:

      Heyyy your group we’rent the only one who nearly blew the multimeter. we had a faulty multimeter too. If only there was a way to check if all the multimeter and the other materials used was in working condition. We we’re lucky we change the multimeter, imagine if we used the faulty multimtere. I reckon we would have got the wrong readings. Now that would be a dissaster.

  12. Lovleen Says:

    Wow… quarks are very interesting sir. Why don’t we study them in a bit more detail???

  13. Paktia Says:

    Coming into the EPI, I thought i had studied enough to get a basic understanding of the task, but when we were given our material, I was shocked at what I hadn’t known about.
    Our group started out well, but when it came to measuring the resistance, we were in some trouble, having no clue of what do to. Overall I think we went okay in the EPI, but come to writing the log book, we had to rush it and couldn’t complete it.
    If more planning and taking the EPI more seriously than it was taken, would’ve made the results much better.

    • alvin Says:

      The EPI was difficult man and i struggled to comprehend the tasks required to complete also for i did not prepare enough. I believe if Lovleen was not apart of our group we would have struggled immensley. But overall our group did well and hopefully yours did too.

    • sahil26 Says:

      Also, teamwork is a key…. there is no way you can just be “carried” to a good result by other team mates. I think assigning ” equal work” to people is important.

      • Jay Says:

        Yeah, teamwork is definitely something that has to be working well for the group to succeed in the EPI. Even with the basic understanding of the concept, we really did struggle with using the multimeter and setting up the circuit correctly. Sharing the work load is the best way to succeed but also you have to try and get each individual from the group working on something that best suits their strengths so that they contribute to the group and help them succeed.

    • Dinel Meyepa Says:

      nah, i don’t reckon it was that challenging. Just needed more time, with more time, we would’ve been fine.
      πŸ™‚

  14. Patrick Says:

    Don’t be disheartened by your EPI Little year 11’s, Last years group did horribly as well, fact of the matter is, unless you’ve done something like this before year 11, you won’t do so well 1st time around.

    You’ll get better believe me, you guys just aren’t used to it yet, EPI’s are a taste of what it is like to be a real scientist, making you’re own prac, own write up, taking into account every single detail, it’s something you’ll develop over time.

    • sahil26 Says:

      Thanks for the advice. Although, I figured that to take every single account into detail there needs to be a detailed plan too which i think was missing. Atleast now i know that organisation is more important than just being smart in science. *pheww*

  15. Paolo Says:

    Hello,

    Posting a comment about my experiences of the EPI, it was very difficult, good structure and further preparation would have been essential. Overall, good experience, especially if we are having much harder and diverse EPIs in the future.

  16. Lei Says:

    the EPI was so damn HARD! I’m not sure how the others went, but I didt know what to do, and we couldn’t work out how to use the multimeter(i think it was broken), and i guess we sort of ran out of time at the end to write up the report, though everything else went good, though we did get some silly answer, oh well, it was a good practice! πŸ˜€

  17. Samson Says:

    I thought the EPI was fun, sure it was hard and complecated but thats what we were told. but i still found it more fun then anyhting else

    • Troy Cardozo Says:

      The EPI was not the way i thought it would be, It was hard but interesting and good to learn from. Planing the EPI was the most important thing, Answering all the questions without planing would be a waste of time and impossible to do, To plan it out we copied the questions and the data and worked together on what to do. It was good working with my teammates (Samson, Zaki and Levy) since Zaki knew how to use the multimeter and levy and Samson knew how to measure. All of as worked together. It was fun planing although we were not really sure what to do in some places, for eg The graph. The main problem we had in the EPI was to do the graph other than that i guess we were doing fine. We also had to use the time we had effectively. We first had to set up the circuit and record all measurements in the first 2 periods. In the last period we put everything together and did it in time, although we didnt get the right wire name, but it was surely a very good practice to start off with.

  18. alvin Says:

    The EPI was said to be the most difficult task we would complete, i dont think many of us took it serious enough as i am saying on account of my group and myself not planning enough as we should have done. Next EPI i have learnt that no matter how much you’ve planned it is not enough. The experimenting performed when completing the EPI was difficult due to the equipment, it was not working properly for we were not recieving correct results.

    • MITCHY Says:

      haha alvin i agree totally we were warned but did not take it seriously, but any way i think we did it, but if we had of researched properly, because we did know what it was on we would of been a lot better off.

  19. sahil26 Says:

    The EPI was more of a learning experience rather than a great success. Our group had sufficient knowledge about the maths behind the topic but we did not have enough practical knowledge. We had problems with trying to configure the use of a few elements of the circuit ,i.e. rheostat, and how they were to be used to find the resistance of the length of wire we had. Nevertheless, we eventually finished our practical investigation but it was by no means a good result. For futher EPI’s lots of points about the time management and practical research were taken down. I m sure that my next EPI will be better than the previous one as i said this EPI was a learning curve which will help us for success in coming pracs.

  20. Zaki Zulkafli Says:

    EPI, what could 3 little words be such harm to us? Well it was the hardest thing ever. Finding out the resistivty of a wire, pfft how hard could that be? Well we warned on how hard it would be. Maybe some of us took it lightly (me) lol. But when we first started on the EPI, the major thing to do was finiding the resistance of the wire. It was do-able, we found out the length, diammeter and calculated all of it. I would say the hardest bit was calculating the resitivty on the calculator. It was confusing but me and my group manage to do it. We then had the worksheets to fill in. Everything was alright to answer just the last bi where we had to draw a graph. Me and my group was confuse on what to draw.Now the depressing bit of this EPI was the errors we had, it took us quite a while to get the measurement right. I would say i learn how to calculate the resitivty of a wire in conclusion. Who knew measuring the resitivty was hard but it was good that we accomplished this.

  21. MITCHY Says:

    to tell the truth or not, yep the truth it sucked massively if you did not something you didn’t no and had to figure it out within the group but if you all had a great general knowledge you would of been good off from the start, but yet well all got through it and got lots out of it so in a way it might of been worth it, but had no idea about the test we would have to do on graphs afterwards all well it happen.

  22. Jay Says:

    The EPI was a real learning experience for us, with all of the planning that the group did we really only knew how to take the measurements when we walked in for the first lesson. Our group really struggled with the practical part of the EPI but we had the understanding of the topic. We didn’t know how to completely set up the circuit on the first lesson which meant we had to redo all of our results again on the second lesson. The EPI has been something to learn from on just how much preparation will be needed for EPI’s and other practicals in the future.

  23. Paolo Says:

    Hello Sir,

    Could you provide me your school email, so i can send you the graph work, just to show i’ve completed the requirement. I will also give you a printed copy next week if needed.

    Apologies and Thanks
