Wow, where did summer go? This summer must have been the fastest summer I ever experienced. That could be because I’m getting old, and the years seem to fly by that much faster.
This summer I was assigned to teach two summer courses – each five weeks long. Summer 1 Session immediately followed by Summer 2 Session. As usual, I tasked each class to submit a photo to my “Geography Photo Contest” by the end of the term. Have a look at the Summer 1 Session entries here:
Before I knew it, one session finished, then the second one finished in a blink as well. Then my summer was over. Maybe my summers would seem longer if I didn’t teach so much. I think I just don’t like to take more two weeks off. Anything after that, and I start to get lazy.
These last few are from the second session — which ended what seems like five minutes ago.
I have been enjoying my students submissions, however I think I may have to reword the original assignment. Students were supposed to write a caption for each one of their photos (something about maybe 100 to 200 words). I think too many of them took that to task. They want to earn a high score, and wanted to make sure that they wrote a good answer, but sometimes this resulted in slides where there was way too much text. This minimizes the room for the photo — and the whole point is to SHOW THE PHOTO! They are supposed to relate their photo and observation to a geography concept, but most could have simplified their statements. I may have to re-word this assignment.
I like all the entries. I wish we could talk about their ideas more.
Does the text help or detract? Do any of these appeal to you? Let me know in the comments below.
24 Hour Photo! It always used to be that you had to wait days until the photos you took were developed. Now, of course everyone can view their pictures right away on digital cameras and smartphones. It used to be a big deal to be able to get your photos back in a day There were even businesses which advertised how fast they were — One Hour Photo stores and the like. Some of them were open 24 hours — and you could make photocopies.
My students did a good job finishing their “Geography Photo Contest” assignments all on the same day. At first I thought that maybe I forgot to post the assignment. They were not being posted — as opposed to previous semesters. Even after the first student finally posted, I still wondered what was going on …
It must have been a busy final week of classes. There was no way that students could not possibly as thrilled as I am with this assignment … just before finals …right?
Although this is a smaller batch, my students are to be commended on their 24 hour burst of creativity.

EIGHT WEEKS A DAY – More Geography Student Photos! A play on words, you say? You probably thought I meant “Eight Days A Week” which was a song by The Beatles – and was a play on words itself. What I mean is that my students in my EIGHT WEEKS course have finished their term. These half-semester courses are a good way to gain general education credit quickly. However, 8-weeks students know that the course will proceed twice as fast as regular semester-long courses. To their credit, they came through with the Geography Photo Contest assignment. Please enjoy more of my student’s photos:

Oh, where can you listen to The Beatles song? Here on this YouTube link. The music video includes many scenes fron their famous performance at Shea Stadium, New York — where they played for more than ONE HALF HOUR!!!
The plant hardiness zone map is useful for horticulturists and gardeners. The map shows what the extreme coldest temperature is, on average of any given winter. The idea is that plants which winter over have to withstand the coldest temperature in that environment. Fruit trees, and perennial flowers must be adapted to environmental temperature. If the winter temperature goes below what the plant can stand, then that plant species cannot grow in that environment. This gives gardeners and other horticulturalists a basic guide as to what temperatures they can expect in their region. Of course, there are many other factors to consider when planting.
These maps are updated periodically. Individual state maps are also available from the USDA ARS site. This is one for Ohio:
These include more precise data with mapped sub-zones of each major zone shown on the main map. For example: If you are in Sandusky Ohio, on Lake Erie, you are in zone 6a. The coldest temperature of the winter is on average between -5 and 0 degrees Fahrenheit. Just a little farther inland, you are in the next zone — 6b, where the average coldest temperature of winter is between -10 and -5 Fahrenheit. Quite colder over just a short distance! This demonstrates the moderating influence of the proximity of large water bodies.
Here is a helpful YouTube video which explains the usefulness of these maps:
What will be the theme of the next map? Check back next week to see Map #3!
Notice: I told my student bloggers that a good way to generate views on a blog is to create a regular SERIES of posts on a theme. I will lead by example, so today I will start a seven-part series on “interesting maps of the USA”.

Map #1: “How much snow does it usually take to cancel schools?”
Growing up in northern Ohio, I saw my share of snowstorms. The 1960s and 1970s were an especially snowy portion of our climatic history, with many record setting snowfalls. However, it took more than a slight dusting of snow to close the Ohio schools where I lived! It would take TWELVE INCHES to cancel our school day. We were used to snow, and knew how to drive in it. They wouldn’t even THINK about closing school with less than six inches. There are other regions ever better adapted to high snowfalls. You need TWO FEET of snow to close some Rocky Mountain schools. Compare that to the southern areas of the US where an insignificant amount of snow would cause auto accidents and close schools. The population is just not used to travel over snow. I won’t bash bad southern drivers too much though. Many of these areas get less than an inch of frozen precipitation each year. They are more likely to get 1/4 inch of freezing rain, than six inches of snow. Freezing rain is much harder to drive on than melting snow (even for a northener). I feel sorry for southern drivers. Much as when you get on a boat, you have to find your “sea legs” … when you drive on ice for the first time you need to learn your “ice brakes”.

So long until Part 2, when I will share another interesting map of the US …
Years ago, I used to collect postcards. When I would travel for a conference or if I visited an interesting place on vacation, my wife and I would often window shop through shopping districts and tourist areas. Whenever I would stop into a touristy place with a lot of those nick-knack shops, I would always pick up a few postcards. Post cards are cheap, they are easy to carry and pack for the return trip. What else should I buy? Another mug? A plate? a spoon? A T-shirt that says “XXX WWW XXXXX” ? None of that ever had any appeal to me. But I liked postcards. The shopkeeper (“May I help you”), would always be happy that I would be buying ANYTHING. Most tourists just browse through the shop and fondle the snowglobes. I wouldn’t mind having that samurai sword though. Sometimes I would send the cards to friends, just to let them know that I had a job where I get paid to go to educational conferences, and where I can eat at upscale restaurants on the taxpayers dime. Somewhere between when I stopped traveling so much, and the invention of the Internet, I stopped collecting postcards.
One of the themes I liked was MAPS on postcards. With that in mind, let me share with you some maps of my home state on postcards.

I wanted to share this map, another faculty person recently posted.

I know … there is a hierarchical classification to world soil types. Soil types are categorized by their similarity. Here I will zoom in a little closer to North Carolina. It is a good LOOKING map at least.
You are still supposed to use the same legend as above. I looked at this and thought — where are the Ultisols?
Unfortunately, the map above use the United Nation’s Food and Agricultural Organization soil classification. It looks like we are somewhere in between Ferric-Acrisols and Gleyic-Acrisols. Huh? That is all too complicated for me. Actually, I do not like or appreciate this particular world soil classification — at least not for general education. I much preferred the “Seventh Approximation” classification, which was a taxonomic system that was similar to biological classification. Here is a good video clip.
Certainly for teaching in general education the Seventh Approximation is better. Just knowing the characteristics of each Soil Order would be important for students to learn. There is a reasoning for each of the root words in the soil order name, which says something about the environments in which they formed and developed. This concept is well illustrated in the video below:
If you want to untangle the UN’s soil classification system I suggest these global soils links:

“Questions and Answers” — Students can easily participate in a classroom lecture about basic Earth-and-Sun Relationships. Let me share a few examples of that I sometimes use:
1.Show the Earth-Sun relationships diagram from your textbook (if you use one). I use the Lutgens and Tarbuck “The Atmosphere” textbook from Pearson Publishers.
2.Make sure that you have already answered the question about the distinction between Earth rotation and revolution. They also need to know about the globe grid system (Equator, Arctic Circle, etc.) Then, you can explain the question as to “Why We Have Changing Seasons”.
3.State these are the items to watch for in the video/animation/lecture.
When is the summer solstice, winter solstice, autumnal equinox, and vernal (spring) equinox in the Northern Hemisphere?
What are the sun angle and day length conditions on these dates? Especially note where the 90 degree noon sun angle is located on these dates.
When is the summer solstice, winter solstice, autumnal equinox, and vernal (spring) equinox in the Southern Hemisphere?
Also pose this question — Are the seasons really “reversed” in the Southern Hemisphere? Explain how.
4.Show the video, or better yet use a tutorial animation to take a typical revolution around the Sun and describe the Earth-Sun relations along the way.
(Another option is to use a globe. Walk around the classroom for an example of one solar year. Remember to keep the North Pole pointed to Polaris!) Optional: Have a bright-eyed theatre major portray the Sun.
5.Earth-Sun relationships are one basic geographic concept where it is easy to write up objective multiple choice and/or True-False. The answers should not be arguable … as many “answers” in test banks are. Word these on tests so that there is only one clear answer.
For in-class purposes, this is a good opportunity for Questions and Answers! Students do not have to give an elaborate answer. All questions may be answered with a term or a phrase. Sometimes a simple grunt will suffice. They either know it, or they don’t …
Start with easy ones, and then proceed to the ‘tricky” questions …
(Ask a student) Q: Where are the vertical rays of the Sun on the June 21st solstice? They should look at the diagram, then answer “23.5 degrees N” or “the Tropic of Cancer.” (Don’t be like me, and go off on a tangent about what a “tropic” line is.)
(Ask the next student) Q: What season is it? You can leave that question hanging. You are being bad as a teacher if you do not specify the Northern Hemisphere. Likely the student will answer “Summer” – but that just shows our Northern Hemisphere bias. The date is the first day of Summer in the Northern Hemisphere.
(Ask another student) Q: Then what season is it in the Southern Hemisphere? They should answer “Winter” — as the June 21st Solstice is the Winter Solstice of the Southern Hemisphere, the first day of winter in the Southern Hemisphere.
(Ask the next student) Q: How many hours of daylight are there in North Carolina at the time of the Spring Equinox?The student should know that the answer is “12”. Also clarify that “Vernal” means “Spring”. You may then add with a smile … “And oddly, eggs will stand up on that day …”
(Ask another student) Q: Where are the vertical rays of the Sun on our (Northern Hemisphere) Winter Solstice? They should answer “the Tropic of Capricorn” or “23 ½ degrees South.
Basically, give each student a chance to answer a question by looking directly at the E-S diagram.
(Ask a student) Q: How many hours of daylight are there at the North Pole when the vertical rays of the Sun are on the Tropic of Cancer? Point to the diagram where the Sun’s rays shine over-the-pole to a latitude of 66 ½ degrees North (the Arctic Circle). Hopefully, they will say “24 Hours” and add “Yes, you would not see a sunset that day …
At some point you mightget tricky …
(Ask another student) Q: Ok how about … how many hours of daylight are there on … the Arctic Circle … on the date of the Fall Equinox in the Southern Hemisphere?
That seems like a lot! You have Article Circle, Fall Equinox, Southern Hemisphere, which could all be points of confusion … and mental juggling.
Hopefully, the student will see clearly that by you asking “Equinox” there can be only one answer – “12!”. Because EVERYWHERE on Earth has 12-hour day and 12-hour nights at the time of the equinox.
You might add Q: What about at the Antarctic Circle? … the Equator? … the Tropic of Cancer? All answers are of course — 12 hours.
Also say this with a smile: “…and oddly, eggs will stand up at that time”. Who knows, you may get a “is that true?” question from a student who you know is actually paying attention.
This is only one small part of the session. There are many other ways to embellish the Earth-Sun Relationships diagram. There are also many opportunities to discuss various cultural significances to various dates in the solar year.
Of course I add in a lot more questions during live lecture. I want everyone in attendance to participate, and try to give all students an opportunity to answer at least one question.
