The earliest humans knew that the sun’s path across the sky, the length of daylight, and the location of the sunrise and sunset all shifted in a regular way throughout the year.

They built monuments, such as Stonehenge, to follow the sun’s yearly progress.

Today, we know that the solstice is an astronomical event, caused by Earth’s tilt on its axis, and its motion in orbit around the sun.

Because Earth doesn’t orbit upright, but is instead tilted on its axis by 23-and-a-half degrees, Earth’s northern and southern hemispheres trade places in receiving the sun’s light and warmth most directly.

At the June solstice, Earth is positioned in its orbit so that the North Pole is leaning 23-and-a-half degrees toward the sun. As seen from Earth, the sun is directly overhead at noon 23-and-a-half degrees north of the equator, at an imaginary line encircling the globe known as the Tropic of Cancer. This is as far north as the sun ever gets.

All locations north of the equator have day lengths greater than 12 hours at the June solstice. Meanwhile, all locations south of the equator have day lengths less than 12 hours

I spent several hours shooting and editing video and have come to the conclusion that I need to delete some stuff of this hard drive. Also, I discovered that the using the Flip camcorder, model F260, is not exactly what is needed for shooting good video. I am not using the Flip for my next video. It is time to pull out the Panasonic mini DV camcorder and tripod. It takes less time for me to pull video off the DV camcorder into iMovie than downloading clips from the Flip’s flash memory. The next video project will be Father’s Day at the lake

I am experimenting with including movies from Google Earth Pro into my video projects. So far, it is very impressive and easy to use. When this current video project is ready, I will post it online and discuss the procedure.

Well, it is time to head out to the gym for my “old man” walk on the treadmill and some weight lifting.

Have a nice day!

No, I will not be bummed out by not have the seeming unlimited funds of districts around the our nation. Districts that sent hordes of eager participants to this years bash at San Antonio. I will not get any cheese with my whine. On the positive side, I have been lapping up the scraps and crumbs of leftovers from NECC. I have found streaming video http://www.kzowebcasting.com/necc/ and the best part is that I could fast forward through the presenters crowd warm-ups, self-promos, shout-outs, and even parts without audio. Would I pay for this? No. Would I recommend it to others. Absolutely! The chat feature is wonderful. Send you fellow teachers a link to the site on Twitter or IM or Plurk, or Pownce and have them comment and give feedback while viewing a particular presentation. Now, I have been a fan of David Warlick for many years and always love to listen to his presentations. Here is how I see sharing these videos with my fellow teachers in my school.

Set up a Professional Development schedule. Maybe call it NECC via Distance Learning, or Converge, Connect, and Transform Learning. Then, using our email server, set up a group of teachers interested in earning credits in technology. From this group of names, have them create a Pownce account. The reason for using Pownce, is that users can setup Events. When the time for the training comes, send the group a link to one of the NECC webcasts and ask the participants to post their comments and questions in the chat room. I have been impressed with backdoor chat. Our teachers would be using MacBooks, so we could launch iChat with Bonjour to connect the laptops. Now, will our wifi handle the streaming or will we encounter buffering issues? That may be the “$24,000 Question”.

Other cool “take-aways” that I have picked up include Edtags.org. Edtags.org is a social bookmarking site for educators. Diigo and Del.icio.us are great bookmarking site that I use all the time, but they are blocked by our content filter at school. Edtags.org is unblocked and is now high on my personal list of sites to use. I lacks lots of the numbers of users that the other great social bookmarking sites have, and that is fine. I have been busy adding my bookmarks in Edtags.org and marking them for use by my friends only. This way, I can add teachers in my school as users and add them as my friend so they can access my educational bookmarks and add another tool to our learning community.

Mogulus.com is really exciting. However, it does not make the cut of the content filter in our district. It is also flagged for inappropriate content.

I will not be so bold as to consider this to be a master list of tools for the classroom. Hopefully, I will be able to find time to post additional resources.

Well, first of all, I have no real excuse. But looking back at the school year, many factors contributed to not using blogs. One key difference this past year was Twitter. Instead of spending time thinking and writing, I constantly found myself glued to mini blog posts. I have never enjoyed writing. I am a horrible craftsman of language. My writing teachers always told me I wrote like I talk. This was nice way of telling me that in their opinion, anyone from eastern North Carolina is dumb. I feel confident that all my formal writing teachers are either dead, or tucked away in a nursing home by now.

I have also spend considerable time with my students learning to use Google Sites. I set up an account for my classroom which required students over the age of 13 to use their school email account. I had several students over 18 years old and they used their personal accounts from Yahoo or AOL. I did not use it at all with my under 13 y.o. students.

I liked using Google Sites for one major reason- Google Docs. The Google Site Google Docs feature is really nice with high school students. I was able to post PowerPoint, Word Docs, and spreadsheets. If we were studying cell processes, and I found a document I wanted them to read, I uploaded it the the Google Doc site and “shared” them with the students. They could work in teams or individually on projects.

When it came time for students to write their term paper, I had a hard time convincing my students to use Google Docs. They did not like having to log in to Google and uploading and then when they needed their doc, logging in downloading their document and remembering to upload it again. My students did not like the way Google Doc reformatted their documents. So, I will not try that again for term papers. The best tip I learned from this experience- tell the students to buy a cheap thumb drive and story their term paper on it. I loaned two of my thumb drives and the students never returned them. I should have gotten them to leave their cell phone with me until they returned my thumb drives. Oh well, maybe it was worth it.

It is summer time, time to recharge my batteries. Time to turn off the computer and take some walks outside. Gas is too high to ride around…have a good summer!

My students are busy wrapping up this school year. It is difficult for students and teachers to stay on task. Each day, I have been photographing my student’s plant grow projects. The reason I have been doing the photography myself is because many of my students are attending math and/or reading remediation. After uploading this image to our classroom Flickr account, I received a comment from a Flickr user. It was a nice comment.
