This hawk is a biotic limiting factor because it limits populations such as the mouse population. It also limits the population of rabbits, squirrels, and basically any small mammal that can fit in its talons. It does this by eating them.

Camden Aquarium

This past friday, we went to the Camden Aquarium. First, we made groups with our friends, than we were given a chaperone and a bus. My group was on bus number two. After about an hour, we finally made it to the aquarium. After getting off the bus and finding our chaperones, we were allowed in. Although most of my group left us, half of us found a new chaperone after getting lost and half found our old chaperone. The half with our old chaperone got to see all of section D and part of section C, and I don't know what happened to the other group. At the end, we all went to the gift shop, and then went home.

worlds only immortal animal

An immortal jellyfish (turritopsis Nutricula) has been discovered. It was originated in the Carribian but spread throughout the world. Its immortality is thanks to something called transdifferation, or the ability to completely transform from an adult to a polyp and back again. Scientist believe that it can do this to no extent, making it, literaly, immortal.

Math in the Afghanistan Conflict

Most people would think that the war in Afghanistan is only something that has to do with Social Studies, yet there are a few math aspects in the war as well. One aspect is finding out how long the war lasted. Also, sadly, another aspect is how many bombs were dropped. On a happier note, another aspect is how many buildings were repaired and how many people were saved. Finally, there's how many soldiers were braught in.

Wonderful, Glorious Goop

In science class, we had an experiment about the states of matter. On the lab tables, there were beakers filled with "slime" (corn starch mixed with water). We had to find out what state of matter it was: solid, liquid, or gas. My group thought that it was a trick question: that it wasn't a solid, liquid or gas. We thought it was an amorphous solid, which is a solid that will hold it's shape when moving, but will turn to liquid when it stops moving. We later found out that our guess was correct.

Cork Launching

In a recently completed lab, we launched corks with baking soda with vinnegar. The carbon dioxide produced by this foaming mixture has to escape so it pushes the cork out of the test tube. At first, my group and me were using too much baking soda, which didn't launch the cap to the window, which was our objective. Then, we tried using more vinnegar with less baking soda. This made the cork fly a huge 690 centimeters. We tried this method over and over again (about 4 times) because the only thing wrong with our launching was our aim. Finally, we aimed it at the wright angle and the cork sailed through the room and straight to the room. My group and me were extatic.
