The Three States of Matter 1/25- 1/29

Summary
What is matter? Matter is anything that has mass and takes up space. Three forms that matter can be in are solids, liquids, and gases. You can change one form of matter into a different form. Read on to find out more.


 Some properties of matter:

           How it...

  • Looks (shiny, black, colorful, dull, etc.)
  • Feels  (smooth, sharp, rough, bumpy, etc.)
  • Smells (good, sweet, bad, rotten, etc.)
  • Sounds (loud, quiet, echo, soft, etc.)
  • What it Does (rolls, bounces, walks, crawls, etc.)
One state of matter is a solid. Some examples of solids are pencils, books, computers, etc.  A solid is a matter that has a size that always stays the same. The shape cannot change, and it does not take the shape of its container. Do you think an ice cube is a solid?

Another type of matter is a liquid. Some examples of liquids include juice, water, milk, rain, etc. A liquid takes the shape of any container that it is in. It has no definite shape. (In other words... It does not have a permanent shape.)

The last state of matter is a gas. Some examples of gas include air, steam, fog, etc. Gas also has no definite shape, they take shape of whatever container they are in. Ex: When you are blowing up a balloon, the air in the balloon is taking the shape of the container. 

Physical changes in matter change how the object looks, but it does not change the type of matter that it is in. Here are some examples: If you mow the grass, it is a physical change because it is still grass. If you rip a piece of paper in half, it is a physical change because it is still paper. It is not apple juice!

Another type of change in matter is a chemical change, or chemical reactions. When this type of change happens a new matter is formed.  Here are some examples: butter, flour, sugar, and some other materials create a new matter: cake. 

When something is...
  • Burning
  • Cooking,                             
  • Boiling
  • Rusting
A new matter is forming during chemical changes. Look for examples at the end of this blog.
I hope you have learned from my examples and facts. Have you figured out how to change one form of matter to another? Some solids can change into liquids. Example: To change an ice cube to a liquid, you keep it out at room temperature, and it will slowly melt. Do you think an ice cube is a sold? You were right! It is a solid, because it does not take the sahpe of its computer.


SP3: Planning and carrying out investigations

In class we designed and performed experiments to test out a few of our hypotheses. Our hypothesis was that if we put two M&M's in the same container about 2 cm apart the coloring will mix together. Some other groups thought that the colors would not mix together. 

We did the experiment, and it proved that our hypothesis was not true, and that when the coloring from 2 M&Ms comes together, it forms a line. The next day we did the same experiment, but from a cup so we could see what was happening from the side, and we realized that one of the colors was going over the other, and the other color was going under.

Structure of the Periodic Table - 9/25-9/29

https://image.slidesharecdn.com/theperiodictable-110223090122-phpapp01/95/the-periodic-table-7-728.jpg?cb=1298451775 Summary: This week, we have been learning about how the periodic table is arranged and the different patterns that are in the rows  and columns. In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

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 vib...

Energy Transformations - Weekly Blog (1/28-2/1)

Types of Energy  by  Solar Schools Summary: You've probably heard the quote by Albert Einstein, "Energy cannot be created or destroyed, it can only be changed from one form to another." But what are the forms of energy? There are six general energy forms: chemical, mechanical, thermal, light, electrical, and nuclear. Any form of energy can be converted into another form. There are many examples of energy transformations that happen in our everyday lives. The first energy form is chemical energy. Chemical energy is a form of potential energy and is stored in chemical substances. An example of chemical energy is gasoline that is used to power a car. The next form of energy is mechanical energy. Mechanical energy is energy released by a moving object. For example, mechanical energy is the energy that causes a soccer ball to move when kicked. Another form of energy is thermal energy and is associated with the motion of molecules. This means that it is caused by f...
