Regarding animals and the weather, I’d have to say Sam Gribley’s nuthatch would have been a good forecaster. Here, the score is:

goldfinches…1
weatherman…0

The weather report said it was to be sunny and warmer with a fifty percent chance of precipitation. The goldfinches said it was time to eat as much as possible before the weather turned.

We ended up with only light flurries, but by early afternoon, the sky looked ominous and the wind brought a dip in temperatures. Back in the 20s for us! Wind chill is now below zero.

So, fight off the chill and take the goldfinch’s advice. Actually, take a trip to Hawaii and enjoy this week’s carnival of homeschooling.

One useful post I found is some resources for teaching geography. We do map studies with everything. This involves printing up a blackline master and marking physical features according to the color key in our map maker’s kit. Mouse then locates the capital and other important cities. As we progress through our reading, she plots new places on the map. Of course, our current map is of Virginia since we are studying Jamestown.

The focus is primarily on topographical and political maps, but we look at others as well. Since we are also studying geology, we have looked at numerous geologic maps. Mouse is learning about contour maps, and has looked at an interesting sort of geologic map that neither of us can make much of. But they are important for geologists, particularly those searching for oil. Which is probably why the first example that popped up on the search was from Haliburton.

And here is another interesting program for anyone interested in studying geography. I haven’t figured it all out yet, and mostly it is just eerie. Google Earth provides you with a 3-D view of the world through satellite images. If microchips and the ability to track every moves bothers you, this will too. We located our house and were able to recognize our car sitting in the drive. My husband showed the kids his old elementary school and we took a look at the Eiffel Tower.

I can’t imagine how much more detail is available to the government if this is a free download. OK, maybe I can. Back in the 80s, there was a picture in one of the major news magazines which featured a man lying in a park. You could see the time on his watch as he napped in the sun. Nice satellite photo. And that was a long time ago, in technological terms. No wonder the US is concerned about China’s ability to shoot down satellites. Military applications aside, do you have any idea how dependent we are on satellites?

Without them, we’d have to watch the birds to see what the weather had in store for us.

    Just a note to ease your concerns about Google Earth (which is, indeed, a fascinating program) (and which has its counterpart in the Windows Live program) …

    … it is often assumed that because it is so detailed, it is “real time”. Let me reassure you, it is not. I moved into my house 2 years ago. Not only did no Internet map program know I was there, but even Google Earth seemed to think I lived in a dirt lot. It took almost 2 years for them to update to something more recent. (I finally live in a house.) Unfortunately, even though my house is visible, my street is not listed anywhere and only one Internet map service to this day knows that we live in the middle of a huge housing complex. Yeah … I think, as long as you’re not a target, they’re still a ways off of tracking your movements.

    (Oh, and thanks for the heads up on the birdwatch thing in February. I’ll definitely want to take part in that.)

    Oh, it isn’t really Google Earth itself that concerns me. I know it isn’t real time, but it is kind of eerie to think how much those satellites up there can “see.”

    Mind boggling!

    Most of the pictures from Google (and the like) are not satellite pictures. There are a bunch of companies out there that fly over terrain with aircraft and take pictures that they try to sell in various markets. (Note that only populated areas enjoy the “hi res” images. That’s because these companies have no market for areas without population.) I suspect that the standard satellite resolution is what you would see in the areas on Google Earth that are not hi res.

    (Note: I worked on one of the top resolution satellites for commercial use. They were touting a 1 meter resolution. That means, in essence, that they could differentiate between things at least a meter in size. Maybe that will ease your mind?)
