QR codes

Today, you will be making a scavenger hunt using QR codes


STEP 1:  Watch the video



STEP 2:  Find out about qr codes https://sites.google.com/a/lshigh.org/gotbooks/qr-codes
and be able to compare them to bar codes.

STEP 3:  Decide what your qr codes will link to:

  • a website
  • a location on google maps
  • a clue (perhaps on twitter or weebly) that will require you to solve a riddle
  • other ideas
Here's how one person figured it out:   http://ilearntechnology.com/?p=4211
Here is another:   http://storify.com/720mi/qr-code-scavenger-hunt  (this includes the video above, as well as other ideas)

STEP 4:  Plan your hunt and make the qrcodes:   http://www.qrstuff.com/ is one maker that is kind of cool, but there are dozens of them out there.

Your QR scavenger hunt must have at least seven clues, which should be saved as .png or .jpg and pasted onto a word document.  Send this to me at the end of the class.

http://www.instructables.com/id/Drum-Beats-in-Audacity/


http://www.instructables.com/id/Basic-recording-and-editing-with-Audacity/


http://audacity.sourceforge.net/


You must create a multiple track song.  This includes the percussion instrument you made (you'll have to bring it in by tomorrow), your instrument, a synthesized sound from an app, and something else.  Your song needs to be at least 30 seconds long.

Thursday, December 12, 2013

Instructables

music that you create will be a combination of your wind instruments and other sources.  today you will need to look at the app that a company Google Chrome and the homemade instruments on Instructables.  your group must have a percussion instrument to go along with your wind instrument.

Many of you also need to correct your pipe lengths for your instrument.

then go to the Google Chrome App Store and look for music apps that you can use to help enhance your song.

at the end of the hour you will be asked to reflect on your progress.

    Mousetrap car body ideas

    http://www.instructables.com/id/Mouse-Trap-car/

    http://www.pbs.org/saf/1208/teaching/teaching.htm



    Tuesday, November 5, 2013

    Tuesday-Thursday


    What machines will a mouse trap car have?  Well, you need a body, wheels, and a mousetrap.

    The mousetrap is a lever.  What type?  Does this make things faster or easier?







    Here, we have two machines (3rd class lever and a wheel and axle) with an AMA less than 1.  What does this do for the racer?   How can we maximize this factor for the wheels?
    ===============



    BY 12:30, please tell me or Christine if you are going with Option A, Option B, or Option C.

    If you choose to analyze a pre-made video, you'll need to do the following.

    1.  Watch the video.  Note the times that you observe the terms above.  For example, you may see negative acceleration at :42-:54   You need to use all the terms above.
    2.  Put the terms in order of time, not in the order above.  This will help you think about the way you are going to speak about things.
    3.  Listen to some color commentators in a sports broadcast so you understand better what you are asked to do.
    4.  Start writing your script.  I will ask to see what you have done tomorrow.

    If you choose one of the other two options, please plan out what you are going to do on paper.  Again, I will ask for your documentation.

    Friday, November 1, 2013

    Final Project

    All videos must show evidence of the following.  You must define the term individually and hand in, as well as including a stick figure example of each.


    • Newton's First Law
    • Momentum
    • Pressure
    • Inertia (non-moving)
    • Inertia (moving)
    • Impulse (F vs. t)
    • Newton's second law comparison of two objects
    • Balanced forces
    • Unbalanced forces
    • Pairs of forces
    • Mass
    • Constant speed
    • Acceleration, +
    • Acceleration, -



    Option 1:  Choose a YouTube video of a motorized sport. Identify each of the above terms and and a time associated with it.  Define each term.  Make a video voice over like a weekend sports' announcer that is entertaining and shows your understanding of the terms using a podcast tool.

    Option 2:  The year after a teen gets his/her license is the most dangerous year of his or her life.  Use your knowledge of the concepts above to help keep kids safe by making a video for http://www.toyotateendriver.com/teens/video-challenge

    Option 3:  Make a stop-motion movie that is at least 10 seconds long that tells a story. Explain in a summary how it uses what you learned in this unit.

    Powers of 10

    http://www.powersof10.com/film

    =======================

    Constellations








    For the last two weeks, we have been studying HOW BIG the universe is, and HOW it was made.  Today, you will be creating a personal 2-sided model on your understanding. A model can be a picture or  a concept map with explanation, or a series of statements or a story that are somehow connected. At any rate, your model is UNLIKE anyone else's, because you are a UNIQUE person.  TO start this activity, I would suggest you look around at the links, writing yourself notes and sketching ideas for at least 30 minutes.


    SIDE 1:  Tell me about our star, our solar system, our local galaxy, and the local galaxy cluster.  In some way, represent the following

    • stellar life cycle
    • terrestrials
    • gas planets
    • asteroid belt
    • Kuiper belt
    • powers of 10
    • life
    • gravity
    • orbit
    • Milky way galaxy
    • black hole
    • spiral arms
    SIDE 2:  This model is a V.  At the point of the V, place the words Big Bang.  At the top of the V, put "about 14 billion years"  Then, using the diagram above, and the links below, fill out the V scape to show your understanding of:

    • energy
    • pieces smaller than atoms
    • fusion
    • galaxies
    • size of the universe
    • local galaxies
    • stars
    • chemical elements
    • speed using the Doppler effect
    • supernovas
    • dust clouds (nebulas)

    Please give any mini-marshmallows that you brought to Melyssa.  Melyssa will label them and put them in the wooden back cupboard and we will use them for tomorrow.

    Hand these models in at the end of the hour.

    Our Sun


    Life Cycles

    What happens as a star moves through its life cycle? This is a journey to find out. For each step, I need to know the following


    • the size of the star
    • what it is made of
    • the tools we can use to study it
    • the balance between pressure and gravity
    • if fusion is happening
    • if burps or eruptions are happening

    Our Dyanmic Earth



    Use the Internet to research the geographic region known as the Ring of Fire. They should look at the following Web sites and others they can find by searching:
    As they go through the sites, answer these questions:
    • Where is the Ring of Fire?
    • Why is it called the Ring of Fire?
    • What does the Ring of Fire have to do with plate tectonics?
    • What events on the Earth's surface tend to occur in this region more frequently than in other regions of the Earth? Why do they occur here?
    • What do trenches and mountain ranges have to do with the Ring of Fire and plate tectonics?

    What should you do about it?

    Climate change.  It matters.


    Today, you need to figure out what we should do for climate change.  It must involve the following:

    a) bringing the geochemical cycles into balance
    b) deciding what you do should do differently to reduce your carbon footprint
    c) figuring out how methane and carbon dioxide move around the geochemical cycles
    d) deciding if there is technology out there to store carbon or methane, or if it still needs invented
    e) deciding on what the best strategies should be to control energy and population


    EEEEEEEEK.  That's a lot of information to process.

    First, break it down.

    Define the following:


    • geochemical cycle
    • carbon footprint 
    • methane
    • carbon dioxide
    • energy sink
    • population control

    Now, figure out where each of those fit in the 

    Carbon Cycle

    Water Cycle

    Nitrogen Cycle


    Find out how population changes the geochemical cycles

    Find out about your carbon footprint by using a calculator or two (there are dozens)


    You will turn in your group notes and a poster at the end of the class.

    The poster should identify the three most important worries we have about climate change.

    It should also identify what YOU can do differently

    Solar Oven Questions

    1.  What was the temperature change for the


    • chocolate
    • marshmallow
    • oven temp

    2.  How many data points did you take for the marshmallow?  Can you tell if the marshmallow heated at a constant rate/min or a changing rate from your graph?  Why or why not?

    3.  Which got hotter--the chocolate or the marshmallow?  How can you tell?

    4.  Did you use insulation in your oven?  Why or why not?

    5.  Did you use reflection in your oven?  Where or why?

    6.  Did the color of the oven matter to you?  Why or why not?

    7.  How often would your oven need to be adjusted for the moving sun?  Why do you believe that?

    8.  Compare your data to another group.  Look at a picture of their oven and make a sketch.  Write the group names down.   Which oven was better and how do the designs compare?

    9.  Draw a sketch of your oven.

    10. Where is radiation, conduction, and convection present in the design of this oven?

    11.  If you had to depend on your oven to sterilize water or cook food, how high are the odds of your survival?

    12.  Why is solar power such a big idea for the world?

    Solar Cooker Designs and the Power of Insulation

    Home Insulation

    Part 1:   House R-value simulation

    We discussed r-value and insulation sandwiches last week.  Today, you are going to do work to check your understanding.  Make certain you leave your notebook in the classroom at the end of the day.

    Choose from the three choices below to answer the questions.

    House 1: a cathedral ceiling house, mock-log cabin, with 2 x 4 walls and cedar wall siding
    House 2: a traditional house with an attic, with 2 x 6 OVE wall cavity
    House 3: a traditional house with an attic, with 2 x 4 wall cavity , with brick facing.

    1.  Which house would work best for passive solar heating?  Explain why you believe that.
    2.  Pick ONE of the houses and go to Insulation Design    Decide what type of heat you want and where you are going to build it (you need a zip code).  Make a table from the data you find.





    FEATURER-VALUE
    attic
    Cathedral ceiling
    wall cavity
    OVE-wall cavity
    floor
    type of heat
    zipcode

    3.  Use the Table of Common R-values to calculate R-values for your House Ceiling, Walls, and Floor.  This will show as three different sketches, and must equal or exceed the R-value in the table you just made. 

    Just because something is thicker doesn't necessarily mean it is better.  Sometimes, though, higher R-value material is more expensive.  It's a trade-off, just like many things in life.

    4. Also, when it comes to windows, we have a problem...It is going to be a very thin sandwich, unless we put up drapes (curtains) or some sort of a quilted batting at night.  Even so, that part of the wall will be colder.   The other trade-off is that windows that have bigger R-values have a bigger cost.
    Based on this, what type of windows do you think your house should have?

    Be ready to share.  When you get done, you can start building your solar oven.  You will have half of the period tomorrow to work on them as well, and we will be using them on Wednesday.

    Solar Power Basics

    Sun Research




    Today, we will be asking questions about the Sun. 

    Step 1:  Open up your Google Doc about the Sun.   SHARE this document with me and your teammates.


    Step 2:  Answer the following questions to the best of your knowledge.  This will require you to SEARCH on Google.  When you get the answer, write it down in ONE to TWO sentences, and then paste the URL in.  IF you use a textbook, write down the page that you found the answer.


    • How does the Sun make its heat?
    • How does the heat travel to Earth?
    • How far is it between the Sun and the Earth?
    • Do we depend on the Sun?  Why?
    • What is passive solar energy?
    • How does a solar cell work?



    LAB

    Pick a shiny, a dark, and a light object and place on a whiteboard.  Go outside and gather 10 minutes of data for each in full sunlight.  Then, move the objects quickly to full shade and gather 10 minutes of data.   Your temperature data in degrees C  will be gathered with a digital thermometer.

    Graph the data for all three objects on a graph paper sheet.  Place your independent variable on the x-axis and your depedent variable on the y-axis.

    Answer the following questions:

    1. Which trial had the biggest change in temperature in the sunlight?  How do you know?
    2. Which cooled the fastest in the shade?  Again, show evidence
    3. Which item came closest to its orgiginal temperature by the end of the 20 min?
    4. If you want an object to get hot, what color should it be?  Does your data support this?
    5. If you have a choice of roofing material (light, dark, or shiny) what keeps the summer heat out?  Why?
    6. What is insulation, in your words or in a picture?
    7. What is radiant heat cooling in your own words or pictures?
    8. What is heat capacity (Google it) and how it is related to this activity?  


    =============things to share 









    Home Insulation


    Insulation in Iowa   (take a look at this website)

    Table of Common R-values

    To calculate R-values, we make a sandwich of insulation material.  Just because something is thicker doesn't necessarily mean it is better.  Sometimes, though, higher R-value material is more expensive.  It's a trade-off, just like many things in life.

    Make the following sandwiches for your table on a piece of paper, big enough for the entire class to see.:

    A sandwich with a R-value of 15 or better
    A sandwich with a R-value of 50 or better
    A sandwich with a maximum thickness of 6 inches
    A sandwich with a maximum thickness of 12 inches

    Also, when it comes to windows, we have a problem...It is going to be a very thin sandwich, unless we put up drapes (curtains) or some sort of a quilted batting at night.  Even so, that part of the wall will be colder.   The other trade-off is that windows that have bigger R-values have a bigger cost.

    Based on this, what type of windows do you think your house should have?

    Part D

    USE a SIDE LIGHT 30 cm from the two houses.

    a) close the windows and door with saran wrap or wax paper.   Place a thermometer
    inside of each for 5 minutes and record the temperature change.
    b) make an awning for the windows.   Place a thermometer
    inside of each for 5 minutes and record the temperature change.

    Heat and Weather on the West Delaware Campus.




    Yesterday, you used digital thermometers to gather data.  Today we are going to share that data.

    • 1.  Mark your data points on the map.
    • 2.  Mark another person's data points on your map.
    • 3.  Make sure that both samples are in the same units.  You can use GOOGLE as a conversion tool by entering CONVERT ___F to C.  Alternatively, you can use the formula (°F - 32) x 5/9 = °C


    1. Does your data suggest EVEN or UNEVEN heating on the schools grounds?  Explain, remembering that the greater temperature differences create MORE winds.
    2. If the wind was flying in my face when I stood on the curved section of the parking lot with my back facing the school bell at the old entrance, what does that tell me?  Draw this motion as a large area across the page.
    3. Heat moves from hotter areas to colder areas.  Use a green pencil and create arrows that represent this.
    4. Order the surfaces from coldest to warmest, based on the average temperature you were assigned to find.  All temperatures should be in degrees C.   Make a list from cold to warm of the surface and its respective temperature.
    5. When the air is hot, it rises and the cold air sinks.  What phenomena does that cause?




    Use your map to answer the board questions.

    Claim Evidence Reasoning





    You will be using this site to collect information on three different locations.  You will need to use the process above to gather evidence on the winds affecting these areas.  This is complicated.  Winds occur because of uneven heating and cooling, but they also occur because of the fact that air can contain different amounts of moisture (dew point), there are fronts (large areas of high or low pressure) and there are prevailing winds, as shown yesterday.

    Weather and Energy



    SO far, we have looked at examples of extreme weather and the idea of a natural disaster.  These are not the same thing.

    To go further, we need to look at the concept of energy.


    1.  Go to http://www.wisc-online.com/Objects/ViewObject.aspx?ID=sce304 and take notes.  When you get done, three definitions should be present.





    2.  We will be starting with a lab (mirrored from http://www.pcds.org/share/sci8/labs/concurlab.htm):

    Materials:

    Each group or team will receive one set of materials.

    1. One plastic pan to hold water.
    2. 4 styrofoam cups to support pan and to contain the warm water.
    3. Red and Blue food coloring.
    4. Water.
    5. Test tubes and droppers.
    6. White paper.
    7. Data recording sheets.
    8. Small rocks or rubber stoppers for the seafloor features.

    You will be completing five trials in this experiment, each time you begin a new trial you will
    want to get a new pan of water and refresh your heat source if it has cooled.

    You will be placing the drop of food coloring in different locations and carefully observing its pattern of movement. You will record your observations in detailed sketches done with colored pencils and including directional arrows.

    Be careful not to bump the tables or you will disturb your currents.

    Be frugal with the food coloring. Using only a few drops will allow you to see the currents most clearly.

    Basic diagram of pan and cups.



    Trial A. No heat source

    Place the drop of food coloring in the still water with no heat source.
    The drop of color should be placed at the center of the pan, right on the bottom.
    Draw what happens to the food coloring as you look at it from the side and top views. Be sure to include arrows.
    Write a brief description of what you see.

    Trial B. Heat in Center /Drop in Center

    Place the drop of food coloring in the still water with heat source under the center.
    The drop of color should be placed at the center of the pan, right on the bottom.
    Draw what happens to the food coloring as you look at it from the side and top views. Be sure to include arrows.
    Write a brief description of what you see.

    Trial C . Heat in Center /Drop close to side / bottom of pan

    Place the drop of food coloring in the still water with heat source under the center.
    The drop of color should be placed near the side of the pan, right on the bottom.
    Draw what happens to the food coloring as you look at it from the side and top views. Be sure to include arrows.
    Write a brief description of what you see.

    Trial D . Heat in Center /Drop on top of pan

    Place the drop of food coloring in the still water with heat source under the center.
    The drop of color should be placed near the top of the pan.
    Draw what happens to the food coloring as you look at it from the side and top views. Be sure to include arrows.
    Write a brief description of what you see. 

    Trial E . Heat on one side / ice on other side

    Place two drops of food coloring in the still water with heat source under the side of the pan and a baggie of ice near one edge.
    One drop of color should be placed near the side of the pan, right on the bottom over the heat source. The second near the ice bag.
    Draw what happens to the food coloring as you look at it from the side and top views. Be sure to include arrows.

    Please write your definition for these in your notebook.
    even heating
    uneven heating
    current
    trade winds
