This Day in History 1/28

Twenty-six years ago the Space Shuttle Challenger exploded 73 seconds after lift-off, resulting the death of all 7 of it's crew members. One of the astronauts on board was Christa McAuliffe, the first member of the "Teacher in Space Project." Because the first teacher was going into space, many people were watching the launch on television, including most classrooms across the country. Most people would agree that this was one of the biggest tragedies in the history of NASA. Another disaster like this occurred on February 1, 2003 when the Space Shuttle Columbia exploded upon re-entry into the earth's atmosphere, resulting in the deaths of all seven of it's crew members.

Gas Prices

Check out gas prices around the United States with this interactive price chart.
Change the cities to compare gas prices in cities throughout the US, including Des Moines. You can compare gas prices in other countries as well, like Canada. Change the date range to look at gas prices for a month to gas prices over the past three years. You can really get a good visual of inflation and deflation taking place. If looking at the 1-3 year view, think about events that occurred that may have caused a fluctuation in gas prices. Also, why would other cities have higher or lower gas prices than here in Iowa? Why aren't all gas prices the same across the United States?


The State of our Union


This is a word cloud of the transcript of President Obama's State of the Union address. I found it on the CBS News website. I believe that the words which appear larger in the cloud were used more frequently in Obama's speech.

Some of the larger words are: Americans, jobs, work, energy, tax, Congress, and businesses.
We can probably all agree that most of Obama's address focused on the economy, which is what we're learning about right now!!

Fairness Based Economics

Tax breaks, outsourcing, unemployment, aren't these all things we've been talking about?

Inflation






Inflation Is… A Letter to a Ten-Year-Old (http://gazizza.net/)

Excerpt:

Well, let’s pretend that you’re not happy with the allowance that your parents give you. You don’t have enough money to buy all the bubble-gum, hamburgers, comics or toys that you want. Let’s also suppose that you had a Magic Machine that could print all the dollars you wanted. (This is called “counterfeiting” and people go to jail for doing this. But just pretend that you could print as much money as you’d like.) Since you would have all the dollars from this Magic Machine you could spend as much as you like and would not have to worry about asking your family for a bigger allowance. When you’re on a limited allowance you have to watch your pennies pretty carefully. But if you had a Magic Machine, you could be less careful with your dollars. You wouldn’t have to choose between a new book and a pad of drawing paper. You could buy both and even more! This would be fine and dandy for a time.

But suppose your friends all had these Magic Machines or that you had so many dollars that you gave a lot of them to your friends. Well, if enough of you had loads of money to spend at the local candy store pretty soon something interesting would happen. The candy store owner has only a certain amount of bubblegum to sell. But suddenly, with you and other “rich” kids, there’s a big demand for bubblegum! If he had only 5 packages of gum for sale and there were ten of you who wanted to buy it, any one of you might be willing to pay $10.00 or more for one package of gum. (Remember that back when you had only your allowance, you’d never pay that much for a little pack of gum!) Because of the bigger demand, the owner of the candy store might decide to ask a higher price for the gum — and you will pay it because each of your dollars has lost some of its value. You may seem “rich” but your money has lost a lot of its buying power because there are others who also have lots of money and are “rich.”

In very simple terms, this is what our government has done. Through many decisions made by the officials in the government, there has been an increase in the number of dollars printed. There are just many more dollars—paper dollars that don’t buy as much as the old dollars did. (You’ve probably heard adults say, “Gee, the dollar doesn’t go as far as it used to.”)
