Today in class we read the latest Scholastic News. One of the articles featured polar bears and how global warming is affecting them. We even viewed a few videos on YouTube to further illustrate the growing threat the changing environment plays in making life more difficult for the polar bear.

How much usable soil is there on Earth?
Our class has been studying rock formation, properties of soils, and minerals in Science class the past few weeks. Today the students were able to see a visual representation of the amount of water on the planet versus the amount of soil that can be used for farming. This was eye-opening to say the least. The apple in the photo below represents the planet.
We then cut the apple into 4 equal slices. Three of the four slices represent the water that is found on Earth. This includes both fresh and salt water.
This leaves 1/4 of the apple to represent the land on the Earth's surface.
Of that 1/4 of the Earth's crust, approximately 1/8 of that is considered to be soil that can be used for producing things for our use and consumption.
That is not much soil when you compare it to the size of the Earth. Here is a shot of the apple after we cut it according to the fractions described above.

Latest Wordle:
In surfing the net this evening to learn all about today's historic event, I came across President Obama's Inaugural Address. I then placed the text into wordle and this was what I got. If you have a moment, see if you can spot any patterns.
