Truncated version of a Student Keeling graph - CO2 in the atmosphere from 1958 to present, showing seasonal variation, using data collected at Mauna Loa, Hawai`i.
[If you are a teacher and you decide to use this idea, please let me know. You can contact me for files with grids for graphing, and for charts of the data from 1958 to present.]
In 1958 Charles David Keeling set up a carbon dioxide testing station on Mauna Loa, on the Big Island of Hawai`i. Data has been collected there over the past 5 decades. Here's the web page for the CO2 program. The data can be found here. Remember that -99.99 means missing data.
WHOAAA!! CHECK OUT THE NEW DATA PAGE!!!
The photo above shows part of a graph my 8th graders put together this year. The vertical scale of the graph paper ranges from 310 to 390 ppm CO2. Each class did a graph. Each group did one sheet. Each sheet held 4 years of data. I invite other teachers to do the same exercise!! Let me know how it went.
Each student graphed at least 2 years of data. Some did more for extra credit. Once they had finished their sheet, I had them cut off one end and we overlapped the other end to make this composite graph. Sadly, all got discarded at the end of the year except this one, and this one ranges only from 1958 to 1992. The rest of the classes went all the way to 3/08, and contained 4 more sheets.
So, what's the trend of CO2 in the atmosphere over the last 50 years?
The curvy line indicates the monthly data, with seasonal fluctuations. The red line is a student group's approximation of the general trend of the data. The data itself ranged from about 314 to 386 ppm, from 1958 to 2008, or an increase of approximately 70 ppm. Starting at 314, and increasing by 70 ppm is an increase of 22% .......
TWENTY TWO PERCENT INCREASE IN THE CO2 CONTENT OF THE ATMOSPHERE IN THE PAST 50 YEARS!! That's an increase by more than one fifth! And that was in 2008.
So what? Well let's ignore the global warming issue for a moment. One of the less-discussed results of CO2 in the atmosphere is that it dissolves into the oceans, and forms carbonic acid [a small amount of the CO2 combines with water to form a small amount of H2CO3 in the solution], so this trend in atmospheric CO2 also points toward acidification of the oceans. Scientists have been investigating how this might affect the marine ecosystems, especially the near-surface waters, where the atmospheric gas absorption occurs.
Well, guess what? One thing that an acid can do is dissolve things like calcium carbonate, or reduce the rate of calcification. Now, CaCO3 [thanks phyto] just happens to be the primary ingredient of the shells and casings of various marine organisms, such as clams, oysters, snails/gastropods, corals, and many planktonic organisms such as calcareous algaes. But see the first link in phyto's comment below that indicates some organisms are actually producing CaCO3 at an increasing rate. (see, for example, this article.) So, if some ecologically important organisms (what organisms aren't ecologically important?) find it progressively more difficult to form shells and casings, then what?
Maybe we're being forced to find out. Over the past few years events have occurred where oyster larvae in the Pacific Northwest were dying prematurely. The cause was ultimately traced to pH fluctuations. Now the oyster production process must be adjusted to accommodate these fluctuations -- an adaptation that will only be effective as long as the high pH periods are not too acidic.

So, I really only teach Advanced Photography workshops.. But someone has contacted me and asked if I can teach him Basic Photography in just one sitting, Challenge accepted! haha..
This is me doing the lesson plan, and yes, the floor in my home studio converts into a big whiteboard when I need write something.. When I was doing the advanced photography workshop lesson plan I was using the whole floor for it..

Since 2013, Ben Heine's Pencil Vs Camera concept has become popular in primary and secondary schools worldwide. Heine was quickly contacted by art teachers and schools requesting to use and teach his techniques to their students. They are showing them Heine's creative process through pedagogical worksheets and ask students to do similar images to stimulate their imagination, train their drawing and photography skills, encourage them to use new technologies and motivate them to share ideas and communicate. Heine's work also allows teachers to discuss the differences between observational and imaginative drawing with the art class. The students either create their own artworks from scratch or use Heine's images with the sketch removed to have something to start with

A graph that speaks for itself.
EXTRAPOLATE THAT!! START HERE. If you are a teacher and you decide to use this idea, please let me know.

Here's the web page for the CO2 program. The data can be found here. Remember that -99.99 means missing data. And here is a more direct link to the page with the Monthly data from 1958 to present. I plug it into a spreadsheet and delete the columns I don't want.
WHOAAA!! CHECK OUT THE NEW DATA PAGE!!!
This is part of a graph my 8th graders put together a few years ago. The vertical scale of the graph paper ranges from 310 to 390 ppm CO2. (now it must run to over 400!!!) Each of my classes did a graph. Each group of students did one sheet. Each sheet held 4 years of data. I invite other teachers to do the same exercise!! Let me know how it went.
[For 2011 - 2013 I was lucky enough to have small classes. I had each class do one graph, with each student graphing 3 years on one sheet. You will need to adjust according to your class size(s).]
When I have larger classes I have each student graph at least 2 years of data. I allow some to do more for extra credit, once they show me they can do it well with their first graph. Once they finished a sheet, I had them cut off one end and we overlapped the sheets chronologically to make the composite graph shown in the photo.
I have the students construct a line that they feel shows the average ave the data over the years, or the trend of the data, as a smooth line up the center of the data on the graph.
I also have them find the max. and min. and have them calculate the % change since 1958. They also research what the change has been since the beginning of the industrial revolution.
I next have the students go through the data and each student makes one graph using just the data from whatever month they were born in. This shrinks the horizontal scale and makes the graph much more steep. This lead into a discussion of how to different presentation of the same data may give viewers different perceptions. We also then discuss extrapolation and current trends of carbon production.

Not a great day today, I had a lesson observation this morning and my whole day seemed to centre around it. Beforehand I couldn't think of anything else, and afterwards the adrenaline fade made me so tired I just wanted to sleep!
I hate observations. I know they are a necessary part of teaching, but I think they give such a false picture. Teacher's often put on 'show' lessons that don't reflect their everyday struggles and achievements.
It did go very smoothly, and the kids were fab, but I'm so glad it's over for this term!
Working on plans for our first week back to school after Christmas break. Looking forward to having the students write and illustrate winter themed poems. I'll share a few out of the book "Winter Eyes" by Douglas Florian to inspire some of the reluctant writers. Great book!
Planning lessons (whether for school, university or industrial training etc), is critical to the success of your teaching. Using mind maps for your lesson plans helps keep the learning objectives clear, and allow you to quickly break down the objectives to how you are going to teach that material, and how you will know whether it has been understood and learned. These mind maps show you how to outline the lessons and make sure that everything is in place for an effective teaching and learning experience.

In July of 2005 when I joined Flickr, I expanded my online presence by uploading a DAILY image to this special photo set. Ever since, I've faithfully added one per day. Doing this provides a direct record of my personal experiences. Of course, I started daily blogging in the fall of 2003 and my eJournal and images entries continue every single day as well.
