  1. I've been asked in this thread to write a living books approach to physics. Although I am a qualified teacher in all sciences, my speciality is biology, so I am sure that others (obviously Regentrude) will have suggestions to improve this plan. I hope that it is helpful to all the poets out there (read humanity types) who want to be educated in physics, but don't have an interest in using a mathematical or textbook-based approach. I have found this week-long project to be fascinating! See post 25 for an explanation of *why* I designed this course in this manner. Physics for Poets: a living books approach to physics This will be a conceptual class using 'living books.' It is not a history of science or a study of the biographies of scientists. It is about understanding physics concepts. This class is at a high school level, so although no textbook will be used, the resources chosen are targeted at a reasonably high level. This class could be taught with or without a lab component. GOALS: 1) To understand why objects behave as they do 2) To understand how technology works 3) To study modern physics 4) To understand physics issues in the news OBJECTIVES: 1) To gain a general understanding of basic physics: mechanics, optics, electromagnetism, modern physics 2) To apply this understanding to everyday objects and observations 3) To research current physics topics and understand the importance of large physics projects like CERN 4) To explain both orally and in writing, the physics behind everyday objects and issues in the news 5) To do practical scientific investigations in physics in order to gain an understanding of the scientific method. I don't have time to plan out the labs, but expect them to take about 4-5 hours each (including write-up), so more like investigations than quicky labs. This adds to 20-25 hours lab work, a bit light but still respectable. I have copied an example investigation at the bottom. WORK LOAD I am assuming 6-8 hours per week which includes reading. Reading classes, like English, require more reading hours, so student might find that 8 hours per week is required. Read 5 books (averaging about 45 pages per week) Watch 1 lecture per week Write 5 small papers Make 3 presentations Research and write about 1 larger issue If the work load is too heavy, drop Physics of the Impossible, and reduce to 30 pages per week on average. Your student should read more on reading-only weeks, so that there is more time for the presentations/writing/investigation weeks. RESOURCES Video Lecture Physics in your life - The Great Courses Unit 1. The Physics of Everyday Objects (Mechanics/motion, optics/waves, electromagnetism, digital/machines): 15 weeks. (40 pages/week) 1)The New Way Things Work. Macaulay (400 pages) 2) For the Love of Physics: From the End of the Rainbow to the Edge of Time - A Journey Through the Wonders of Physics. Lewin.

Orzel(250 pages) 4) Physics of the impossible: A Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel (350 pages) 5) Lightweight book: choose one from these three 5a) Surely You're Joking, Mr. Feynman. Feynman. Biography (350 pages) (see Regentrude's post #15 below about possible inappropriate content) 5b) Both The Wizard of Quarks and Alice in Quantumland (380 pages together) 5c) The Physics of Superheros (380 pages) For students with a more mathematical bend, replace selections 2, 3, or 4 with one of these selections, and remove the lightweight book to make more time for the harder selection. 6) The physics of football (300 pages) 7) A Brief History of Time. Hawking. The physics of astronomy. (340 pages) 8) Thirty Years that Shook Physics: The Story of Quantum Theory. Gamow. Requires some algebra but not more advanced math. (240 pages) For students with less time or less-skilled students, remove either For the Love of Physics or Physics of the Impossible (depending on interest), thus dropping out all reading for the last 6 weeks so the student can focus on his/her research paper.

I found to my utter amazement, that the NZ 12th grade physics curriculum includes the exact same writing assignments :blink: (yes, apparently great minds think alike :thumbup:). So I have included here the description of the writing assignments to give some clarity to what I was talking about: UNIT 1: Demonstrate understanding of the application of physics to a selected context Option 1. Semiconducting Today’s society is very reliant on the use of electronic devices. These devices make use of semiconductors, therefore understanding how semiconductors (and the electronic components they are made of) are used in modern technology is increasingly important. Apply your understanding of physics to a real life context. You need to apply your knowledge of circuits and semiconductor physics to the function of a semiconductor component used in an electronic device. Possible electronic devices: light emitting diode (LED) photodiode bipolar junction transistor (MOSFET, CMOS, JFET) light dependent resistor (LDR) thermistor. Research your chosen electronic device. Using your knowledge of circuits and semiconductor physics, explain the function of a semiconductor component used in the electronic device. You are encouraged to use diagrams and pictures to support your explanations. You need to clearly link key physics ideas together to provide a coherent picture of the physics relevant to the semiconductor component. Option 2. Other ideas General – bridge building, musical instruments, sound recording, stellar evolution, radio astronomy, and particle accelerators Specific – GPS and the Large Hadron Collider. Investigate how physics applies to your chosen context. You need to clearly link key physics ideas together to provide a coherent picture of the physics relevant to your selected context. You may choose: producing a written report, preparing an oral presentation (with handouts), preparing a multi-media presentation, or constructing a poster. UNIT 2: Demonstrate understanding of Modern Physics Option 1. Nuclear fusion by 2030 Write a report for your local council about the physics of producing power using nuclear fusion. Research the subject. Write your report. In it, explain clearly the physics concepts and principles at work in a nuclear fusion power generator. Explain also how these concepts and principles work in conjunction with each other to create energy. Based on the physics, discuss the potential of nuclear power as a future energy source for your locality. Conclude your report with a recommendation(s) to the local council. They should be well supported by your earlier explanations of the relevant physics. Option 2. High-powered solar cells Write a report for your local electricity lines business (ELB) about the physics of solar cells. Research the subject. Write your report. In it, explain clearly the physics concepts and principles at work in a high-powered solar cell. Explain also how these concepts and principles work in conjunction with each other to create energy. Based on the physics, discuss the potential of high-powered solar cells as a future renewable energy source for your locality. Conclude your report with a recommendation(s) to the ELB. They should be well supported by your earlier explanations of the relevant physics. UNIT 3: Use physics knowledge to develop an informed response to a socio-scientific issue Option 1. Should your locality remain ‘nuclear power’ free? Conduct research on electrical energy generation using nuclear power. Develop an informed personal response to the issue of your locality remaining nuclear power free based on the physics knowledge. The format of your response is an opinion article for the editorial pages of a newspaper. To prepare for this article you will research and explain the key physics ideas relating to electrical energy generation using nuclear power, identifying the potential benefits and risks to your locality. The benefits and risks may be related to economic, ethical, biological, or environmental factors. Keep a research log book (or folder/electronic record). All your research notes, outlines, drafts, and so on must be kept in this log book. You need to date your work and reference your sources as you take notes. Hand in your log book with your final article. In your article: provide key physics knowledge that includes:key physics concepts and processes that relate to electrical energy generation through the use of nuclear power physics and social implications – the benefits and risks (for example, economic, ethical, biological or environmental) of nuclear power use the key physics knowledge you have gathered to state your personal position and recommended action(s) about your locality remaining nuclear power free justify your position and action(s) by providing supporting evidence to explain why you chose your position and action(s) analyse and prioritise the physics knowledge used to justify your position and recommended action(s). This may include: comparing the significance of implications of the issue on individuals and society considering the likely effectiveness of identified action(s) commenting on sources and information, considering ideas such as validity (date, peer reviewed, scientific acceptance), bias (attitudes, values, beliefs), weighing up how science ideas are used by different groups. Option 2. Renewable energy technology in new buildings – should it be compulsory? In January 2011, scientists published peer-reviewed findings that suggested global energy demands could be reduced by 73% using energy efficient technologies in buildings, industries and transport. Your local council is investigating the feasibility of requiring renewable energy technologies such as solar panels and wind turbines to be compulsory for new buildings. You are the consultant hired to prepare a presentation on this socio-scientific issue for their consideration. Use your physics knowledge to develop an informed response to a socio-scientific issue related to renewable energy technology. You are required to develop a presentation that: gives an informed personal response to the issue of whether renewable energy technology in new buildings should be compulsory includes recommendations of actions that could be taken as a result of your informed position. Research the physics of renewable energy technologies for buildings. This may include photo-voltaic solar panels and wind turbines, identifying the short and long-term benefits and drawbacks to individuals and society. The benefits and drawbacks may be related to an economic, ethical or environmental issue. Develop an informed personal response to your chosen issue of whether renewable energy technology in new buildings should be compulsory, based on physics knowledge. Develop suggestions for actions that could be taken. You will be assessed on the overall comprehensiveness of your presentation, whether it explains the relevant physics ideas, and your analysis and discussion of the issue(s). Keep a research logbook to record your notes, references, article outlines or plans, drafts of paragraphs, comments on the validity, bias or purpose of resources, and so on. This information will help you to prepare and refine your presentation. Topics you need to cover in your presentation provide physics knowledge that includes:physics concepts and processes that relate to the renewable energy technology for buildings. This may include ideas such as energy storage/links to the national grid, conversion between AC and DC, voltage and frequency considerations etc. a comparison of the renewable technologies in buildings with the technologies currently used to provide electricity physics related to social implications – this may include possible short and long-term benefits and drawbacks to individuals, society and the environment use the physics knowledge you have gathered to state your personal position and recommend action(s) about compulsory renewable energy technology in new buildings justify your position and action(s) by providing supporting evidence to explain why you chose your position and action(s) analyse and prioritise the physics knowledge used to justify your position and recommended action(s). This may include: comparing the significance of implications of the issue on individuals and society considering the likely effectiveness of the identified action(s) commenting on sources and information, considering ideas such as validity (date, peer reviewed, scientific acceptance) and bias (attitudes, values, beliefs), and weighing up how science ideas are used by different groups. EXAMPLE OF AN INVESTIGATION Baby bouncers behave differently for different sized babies. This assessment activity involves modelling a ‘baby bouncer’ using a spring-mass system in order to test a physics theory involving two variables in a non-linear relationship. You will take suitable measurements, use techniques to maximise accuracy, process and graph the collected data, determine the equation of the non-linear relationship and critically compare this with the theoretical relationship between the variables. Plan and prepare the investigation The aim of the investigation is to find out how the period of oscillation, T, is affected by the mass, m, which is suspended on the spring. Construct a spring-mass system to model a baby bouncer. Gather data When gathering your data: gather a reasonable range of data points plot the data points and conduct graphical analysis decide what kind of relationship exists between the variables. Account for accuracy and uncertainty in your measurements at all steps during the investigation. Analyse data To analyse your data: Process your data, including uncertainties Transform your processed data in a way that allows you to plot a suitable linear graph that shows uncertainties Determine a mathematical relationship based on your linear graphs that links the period of oscillation, T, and the mass, m. Write the report Write your report using the data that you have gathered and analysed. In your report include: a summary of the investigative process a detailed presentation of your results and analysis, including graphical analysis that includes uncertainties a conclusion that states the equation of the relationship between the variables and compares this to the physics theory identification of how other uncontrollable variables may have affected the results consideration of the limitations of the theory’s applicability in the practical situation and/or at the extreme values of the independent variable a discussion of any unexpected outcomes of the processing of the results and how these have been caused and their impact on the validity of the experiment.
  2. Every year we do a large scientific investigation for our science fair. And I thought that there might be some in the hive who would like to see how scientific inquiry works, especially while we are in the middle of it rather than all tidied up and sugar coated at the end. :001_smile: We are studying Earth Science this year and have done 9 weeks each of astronomy, geology, and oceanography, so there are 9 left for our investigations. Earth Science is always the hardest science topic for kids to study IMHO because the processes are slow (plus I have never studying Earth Science (ever) so I am always at a loss.) I have a 6th grader and a 2nd grader, and the 6th grader will try for the regional science fair this year so there a lot of restrictions on originality and independence. Week 1 6th grader: We discuss what he will study and decide that since he has been reading about Oceanography most recently and has just started learning to sail that he would like to study the ocean. I try to sway him towards studying life in rock pools, maybe how different animals are affected by the tides or prevailing wind etc. He is not interested. "That's Biology; I want to study Earth Science!" sigh. "ok, so what are you interested in?" "I want to study the movement of sand." :001_huh: hummmm. Now, how is an 11-year old going to do that? After some more questioning, he tells me that he would like to see how sand moves differently depending on the location in the bay he sails in. Ok, that is a good question, just maybe not answerable without a million dollars worth of equipment. We go to the library, and find a textbook on seashore ecology which has a chapter on how waves affect animals (my original idea). But not much else. Next, we hunt for articles on sand movement in the peer-reviewed science journals using the library databases. We find that scientists use radioactive sand that they can then trace or they study a shoreline over the period of 5 years. Ok, neither of those are possible. But we discuss how maybe we can use a different color sand and dump it in the water and time its movement and measure its direction. We also brainstorm all the factors that could affect sand movement: sand size, wind speed and direction, prevailing currents, orientation of the bay to the wind and currents (sheltered?), obstacles (rocks, jetties), slope of the shore. WOW. That is a lot of variables to control once we set up the experiment. On Saturday, after sailing he takes a look around the bay to see if the sand moves at all. It does. That is all the information he brings back.:001_huh: Next, we go to a different beach and collect the sand there (which might be a different color), and collect magnetite (magnetic soil mixed into the sand on this beach, it is black and will definitely show up). Finally, we discuss how much he can generalize given the sampling he is considering. Tomorrow, we plan to put the collected sand and magnetite in the water and see if we have any chance of measuring anything, or if this is just a wild goose chase (which it definitely could be). Time: 4 hours including discussions 2nd grader: I start with my this ds trying to convince him that looking at animals in rock pools would be cool (can you see *I* really want to study this) but alas he is not interested. He wants to study how deep the roots of trees go into the soil. :001_huh: I tell him that we could look at this using road cuts, but that perhaps it would be pretty difficult to study. But he does still want to study soil (4 months ago, I read 30 minutes about soil profiles to him, so I am pretty surprised he remembers anything). So we review what we know about soil: layers A,B,C; earthworms, and that is about all he knows. We go to the library and find no books on soil in the kids section and 2 books with a chapter on soil profiles and topsoil composition. The next day when I am out for a walk in the early morning with a friend, I look at the road cuts and notice different layers in the soil. Perhaps we can identify the soil profile using these cuts. I tell ds, and he loves the idea. He packs a backpack and brings a tape measure, a "data collection booklet", a broken pencil :001_huh:, and a trowel. We go to his favorite spot where he digs out "mudrocks" and loves to throw them and watch them smash. I am wondering what a "mudrock" is from the point of view of a soil strata. We get to the site, and start measuring and recording and then promply cannot remember anything about the different strata and how to identify them:lol:. So back home we go, look up the info in the older ds's textbook, take some notes, and go back out. We measure the strata and feel pretty confident. Next, we walk around the woods looking at the different cuts and their strata. Our woods is on a small mountain (large hill) and it was used 100 years ago as a sheep farm so there are lots of old wagon trails that were cut out of the hill side (think Lord of the Rings Weathertop and "get off the road" scenes, because they were filmed 200m from my house). What really really surprises us is that the soil profile just along this one road cut is very different. Top soil thick to non-existant, B horizon 20cm to 150cm deep, or even areas with bedrock exposed. Funny how I have never noticed this before. So, now I ask *the* question: Why? Why is the soil profile different in different areas? We brainstorm a few reasons (I guide him here, but some he comes up with on his own): Slope, vegetation, bikers. He suggests (on his own) that pine trees inhibit the growth of plants under them so that there would be less topsoil where pine trees grow. !!! Excellent thinking and really cool hypothesis. He also suggests that the B horizon is thicker in some areas because in ancient times more soil collected and then over time compacted into b-horizon soil. so.... WOW, this is going to be an AWESOME project. How does the slope and vegetation of the mountain affect the amount of topsoil? If he were 11+, he could win the regional science fair with this one. (or is it that *I* could win? :lol:) Time: 2 hours Ruth in NZ
  3. Move along.... nothing to see here. Actually, since the new board does not allow tagging by anyone but the OP, I am having trouble keeping track of all the big posts I have written since Nov 2012. So I have decided to keep a running list here so that I can just send people to this post and not have to keep tracking down all the things I have written. So, just ignore me while I go troll through all my 3000 posts to see what is valuable, and what is really not. It is going to be a mess for a while as I edit bit by bit over time.

  4. We haven’t done a lot of formal science. I need to try to get my 7th grade daughter ready for high school science and I have 2 years. I am doing BFSU Vol 1 with all of my children (7th down to K) but not at a pace that is going to be sufficent for her. I will continue to include her in that, but I want her to do something on her own. Any ideas? I would especially appreciate ideas that might use what I have. Should I take the 4 science areas and split them up into 4 parts and do 2 each year and just get done what we can? I don’t want to buy an expensive program. Thanks, Kendall
  5. Someone, anyone, just tell me what to do and I will do it. I promise!! We just do not "do" it. I want to do it..the kids want to do it....we just don't....please just tell me what to do. :confused::confused::confused::confused: WTM notebooks don't happen. We have such good intentions and we try, but alas, not so much. My children are (in the fall) 7th grade boy (only mildly interested) and 3rd grade girl (VERY clever and VERY highly motivated) I just can't reinvent the wheel, so I would love to combine at least on some level. Secular would be preferable (though we are Christian). I'll do some experiments. I'll buy extra books. I just need a plan!
  6. I've been having a lovely conversation on a thread on the k-8 board about science activities. I will have to admit that with the exception of Leeyeewah and Rose, it was pretty much a one-way conversation! I think I scared almost everyone off the thread :001_huh:. So I thought I would move it here where the students are older, and the moms (or dads) a bit more jaded about the time they spending setting up and running science activities ;). Why do you choose to do a science activity? Do you have goals you are trying to meet? Do these activities/labs/observations/experiments/demos meet your goals? How do you know if your goals were met? Think first about these questions and then read my x-posts. (I don't want to completely sway you.) I am really curious if I am the only one who doesn't follow science curricula as written. If you change the suggested activities, why do you change them? Ruth in NZ
