Oreos: Are they as addictive as cocaine

Hey guys, i'm back with another topic that I thought was very interesting. Today i'll be talking about oreos and if they are as addictive as cocaine. Studies show that rats treat oreos as addictive as cocaine. scientists at Connecticut College conducted an experiment on rats using a maze with rice cakes at one end and oreos on the other. The rats were observed on both sides of the maze.

The experiment results were compared with previous tests done on rats that were given shots of morphine or cocaine on one side of the maze and saline on the other. The study showed that the rats the weren't given shots of morphine, cocaine, or saline had spent as much time on the side with oreos as the rats that were given shots of morphine, cocaine, or saline did. Also, according to the studies, rats liked to eat the filling of the oreo first, just like many humans do. The studies also showed that oreos activated more neurons than the morphine or cocaine. So when you have a craving for oreos, blame it on your brain chemistry.

That's all for today guys, see you next week.

Chemical Reactions

Hey people i'm back and i'll be talking to you about chemical reactions. Did you know that chemical reactions happen around us all the time. A chemical reaction is even happening right now while you're reading this. Anyways, lets get back to what I was saying. The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus also contains a mix of positively charged protons and electrically neutral neutrons.

The nucleus is what is in the center of an atom. Shells are what electrons are on that surround the nucleus. Clouds are what happens when electrons spin around really fast. Now i'll be telling you about how many electrons can each shell hold. The first shell that is closest to the nucleus can hold two electrons. The second shell can hold eight, then the third can hold sixteen, then the fourth can hold thirty-two. Valence electrons are the electrons that are on the outermost shell.

Now i'll tell you the difference between when an atom is unstable and when an atom is stable. An atom that has a full shell is called stable. An atom the doesn't have a full shell is called unstable.


That's all for today people see you next week.

The Periodic Table

Hey guys i'm back and today i'll be talking about the periodic table of elements. You're probally wondering who made the periodic table and why. Well, the person who made was a scientist by the name of Dmitri Mendeleev, and he made the periodic table for elements, but he left spaces knowing some elements would be discovered after he died. The Periodic Table is a list of all the chemical elements that occur in the universe. It also categorizes elements according to the property of their atoms.Atoms are the smallest units of an element. They are made up of a nucleus composed of protons and neutrons and a number of electrons orbiting in different shells, or orbitals.







It's the numbers of protons, neutrons, and electrons in an element's atoms that determine its properties. The configurtion of these three particles is the only thing that makes one element different from another.

The modern periodic table of elements organizes elements so that it's easier to see how elements relate to each other. First you need to know how the elements are listed on the periodic table. The elements on the periodic table are listed by their atomic number, or number of protons in their atomic nuclei.






That's all for today people I might be blogging next week, PEACE.

Compounds and Mixtures

Heeeeeey i'm baaaack, and I have something else to teach you peeps about. Today i'll be talking about Compounds and Mixtures, and who thinks they know that compounds and mixtures can't get confused between each other. For some people that's true but for others it might not be that easy for them to not get confused between them, and trust I do too sometimes. Anyways, back to what I was saying, a compound is when a chemical change takes place, cool right, yeah not always. Sometimes those chemical reactions can harm the planet and they can also harm you.
Mixtures are when two or more elements, or compounds, are blended without combining chemically and ta-da you have a mixture. Oh and guess what else is cool, each substance in a mixture keeps its own properties. Mixtures can only be seperated by physical or mechanical means. An example of an homogenous mixture is a bottle of salt and salt crystals that have been dissolved in water.

Another example is trail mix, which has a mixture of many diferent things. Trail mix is a heterogeneous mixture and an example of a homogenous mixture is food coloring.

Atoms&Molecules

The Atoms Family

Years ago there were around 2,400 elements. There was a Greek guy named Democritus argued everything in the world was made up of particles so small that they couldn't be cut in half. Democritus called these tiny things Atoms which came from the Greek word Atomos which means indivisible.
Somewhere in the 1800's another guy named John Dalton refined the idea with his theory that atoms are the smallest particle of an element that retain its chemical properties. That means if you were to break apart an atom of an element such as carbon, its not carbon anymore.
Atoms are made up of something smaller then itself. Those things are called Protons, Neutrons, and Electrons. The atom's center, or Nucleus, is a cluster of protons and neutrons. Protons have a positive electrical charge, and neutrons have no electrical charge.
The Nucleus is held together by something called the Strong Force (as in the picture below).

   The inside of a carbon atom is made up of 6 Protons and 6 Neutrons. Electrons surrounds the outside of an atom's nucleus going as fast as the speed of light. If we were able to see the electrons it would look like a fuzzy cloud.
