The Periodic Table Of Elements (2/8-2/12)






http://sciencenotes.org/printable-periodic-table/

Summary:

Have you ever heard of a periodic table and wondered what it is? Do you know what an element is? If you want to know more, than you are at the right place!

Elements of the Periodic Table.

Look at the elements in the periodic table above. In the top left corner there is a number, and the elements are in numerical order. That number is the atomic number. Each element has a different atomic number. The atomic number is the number of protons in the atomic nucleus.
On the top right corner there is another number. This number is the melting point of an element. This number is usually in C°. Some of the elements say "unknown" because scientists have not figured out yet what the melting point is. Example of a melting point: The melting point for titanium (Ti) is 1668 C°.

Each row in the periodic table is called a period. There are 7 periods in a periodic table. The first period only has 2 elements! (Hydrogen, and helium.) Do you know which row has 32 elements? It is the 6th period. The elements in rows have different properties.
The columns in the periodic table are called groups, or families. There are 18  groups. Each  element in a group has a similarity. Think about it like this: The families look alike, and have similar properties just like in real life, but the neighbors (periods) are close, but they do not look the same, they do not have the same properties. Just like in the periodic table! 

Atoms and their Structure

Are you wondering what an atom is? Matter is made from atoms. Practically everything is made from atoms! But... are you wondering what an atom looks like? Well that is pretty difficult because atoms are super, super large. There is something easy about atoms though: they are made out of some easy parts. They include the nucleus (protons and neutrons) and electrons.

 Imagine an atom like our solar system...

 Are you wondering what the nucleus is? The nucleus is the center of the atom. Imagine the nucleus as the sun. Inside of the nucleus there are 2 parts: the proton, and the neutron.

 The proton has positive charge. Some atoms have many protons, but some atoms (e.g., hydrogen atoms) only have 1 proton! It depends on the type of atom. A proton is part of the nucleus. If the atom was the size of a football field, then the proton would be smaller than a marble. If you think that an atom is small, think about the proton inside of it!!

The other part to the nucleus is a neutron. The neutron has a lot of mass, but no charge, it is neutral. All neutrons look the same. The number of neutrons affects the mass, and the radioactivity of the atom.

 Another part of an atom is the electron. The electron are pieces of electricity that move from one atom to another.  They are negatively charged. You might be thinking how small a proton is now, but electrons are even smaller!

 When elements are in their usual form, they have the same number of electrons as protons. When they change their state, that number could be different.

 Here's a joke just for you!!!
An atom walked into his classroom looking very sad.
The teacher asked him "Why are you sad?"
The atom replied "I lost and electron."
The teacher said "Are you sure?" 
"Yes, I'm positive!" replied the atom. 

SP8: Obtain, evaluate and communicate information

This week our class engaged in discussions with scientific peers. We worked on a few documents to get more understanding about the periodic table. We analyzed data from a few presentations, and we worked with our table groups to write a sentence each about what we learned that day. I learned a lot this week with my table group.

Fun Facts!
  • The only letter that is not in the periodic table is "J".
  • Every name in the periodic table has a symbol that is not always based on the element. Example: The symbol for silver is Ag.
  • Francium (Fr) is the rarest element on earth.
  • Argentina is named after the element silver.
  • 90/109 elements are found in nature.
  • 19/109 elements are only created in a laboratory
  • 5 of the elements are named after people (Einsteinium after Einstein ... and 4 more)

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vibrate, mak

Three Sisters - Plate Tectonics (3/19 - 3/23)

https://upload.wikimedia.org/wikipedia/commons/5/5f/The-Three-Sisters-Szmurlo.jpg Summary: Do you ever wonder how some famous landforms such as mountains and islands are created? There are eight main tectonic plates on the surface of the Earth that make up the lithosphere. The movement of these plates is what causes landforms such as mountains and more. The three sisters mountains in Oregon were created by the movement of tectonic plates over a very long period of time. The three sisters mountains were created by the collision of subduction zones. Subduction zones are a type of convergent boundary where one of the places contains oceanic crust, and the other contains continental crust. The two plates collide, causing the oceanic crust to move downwards into the asthenosphere. The collision that created the three sisters mountains was between the Juan de Fuca tectonic plate and the North American tectonic plate. These amazing landforms were also created by land erosion.

The Food Chain (10/26-10/30)

This is an example of a land food chain http://www.sheppardsoftware.com/content/animals/kidscorner/foodchain/foodchain2.htm Summary: This week in class we started to learn about the food chain. We watched a video about the food chain, and then we had to answer a few questions. First you need to know that food chains always start with plants and end with animals. But remember, humans are animals. Humans are usually at the top of the food chain. But that does not means that they are always at the top, what if a lion ate the human! Then the lion would be at the top of the food chain. There are different types of food chains. If you want to see a full list then go to this website: http://examples.yourdictionary.com/examples-of-food-chains.html . In the video they talked about the ocean food chain. The ocean food chain is a food chain that happens in the ocean. Here is an example of an ocean food chain: phytoplankton (tiny little plants), get eaten by zooplankton (tiny animals
