Interactive Temperature Game

I learned from this game that temperatures are very different numbers depending on the way you measure them. For example, you can measure temperature in three different ways, celsius, fahrenheit and kelvin. I never heard about kelvin before. All of the different temperatures are vary different. For instance, freezing point in kelvin is 293, in celsius is 0, and in fahrenheit is 32. Those are all very different numbers. Overall, I realized that there are many different ways to measure temperature and our normal fahrenheit is just one way to measure it.

Popcorn Lab

Did you know that when you pop popcorn in the microwave, it's radiation? The popcorn kernels get heated up in the microwave's radiation which cause it to pop into the white popcorn that we all love! Also, all the popcorn kernels do not pop at the same pace. Finally, the amount of time that you pop the popcorn matters because if you leave it in for 1min. 30sec. then it will burn, however, if you pop it for 1min it will be perfect.

Tropicana: Trying To Make a Greener Orange Juice

Who: PepsiCo(owns Tropicana)

Where,When,What,Why: An average half-gallon carton of Tropicana Orange juice surprisingly contains 3.75 pounds of carbon dioxide. People who worked at PepsiCo at first thought that the carbon dioxide was coming from transporting or packing the orange juice, but they were wrong. The carbon dioxide was actually coming from the fertilizer used to grow the orange trees. A lot of natural gas is used to make nitrogen fertilizer and a lot of fertilizer was used to grow orange trees. The solution they came up with was to make a greener fertilizer. With the help of two agricultural companies, Yara International and Outlook Resources, they produced two low-carbon fertilizers. One of them is a calcium based fertilizer that would almost completely eliminate overall greenhouse gas impacts. The second one is using organic and renewable feedstock like biofuels. Tropicana is testing these at SMR farms to see id it reduces the carbon dioxide. This may seem like not a big deal but this my be huge. In this article it says that this could have a major impact on US farming and the corporation of PepsiCo. This small change in changing fertilizer could result in a set closer to living in an Eco friendly weird.

Deciphering the Chatter of Monkeys and Chimps

Who: Klaus Zuberbuhler, Robert Seyfarth, Dorothy Cheney, Marc Hauser

Where: Tai forests of Ivory Coast

When: January 12, 2010

What and Why: Scientist believe that Diana monkeys in the Tai forests of the Ivory Coast have their own type of language. It was discovered before that monkeys have their own language, however, they can now decode it. Dr. Zuberbuhler reported that these monkeys can vary individual calls by adding suffixes. For example, "krak" means they see a leopard, their predator, coming but by adding "-oo" to the end of it to make "krak-oo" that means they have not seen the predator but heard others say the have. Some other "words" are "boom boom" which means I'm here, come to me, "boom boom krak-oo krack-oo" means a tree is falling and "pyow-hack" means let's get out of here in a hurry.

My Opinion: I think this is amazing. I never thought that monkeys actually had meaning to what they were saying, I thought they just called out random things. The way theses monkeys formulated their own kind of language makes me wonder if other animals have done the same.
