10 Amazing Science Experiments you can do with Eggs

Watch these 10 amazing science experiments you can do with eggs. Very wow! And very simple to do. 

Comet on October 19

Be very excited. On October 19th something ridiculous is going to happen. A rare comet from the Oort Cloud at the edge of our solar system is going to fly past NASA’s MAVEN robot as it orbits around Mars.  It’ll be so close that they’re going to postpone work on Mars and study the comet for five days.

This will be the closest a comet’s ever gotten to Mars in human history and it’s coming from so far away that it’s likely going to have a lot of material we otherwise couldn’t find in the solar system very easily.

The chances of this happening are far less than one in a million.

Matter

Matter is anything that occupies space and has mass. Example, wood, plates, clothes, shoes, etc.

Classification of Matter
a. Pure Substance
     i. Element - the simplest pure substance
                     - composed of only one kind of material
                     - ex. silver, iron, aluminum
    ii. Compound - consists of two or more elements always in the same proportion
                          - can be separated into simpler substances by chemical means
                          - ex. salt, water
 b. Mixtures - two or more types of substances
                   - variable composition, can be separated by physical mean
    i. Homogeneous - the composition is uniform throughout the sample
                              - ex. air, salt water
    ii. Heterogenous - nonuniform composition
                              - ex. pizza, water and sand

States of Matter
a. Solid - has both distinct shape and definite volume
            - atoms are arranged orderly
b. Liquid - has a distinct volume but dependent of its container that is occupies
c. Gas - does not have definite shape or volume
           - particles are far apart, there's only little attraction
           - conforms to the volume and shape of it's container

Properties of Matter
a. Physical Property - a characteristic of the substance that can be observed/measured, such as color, shape, odor, luster, size, melting/boiling point and density
b. Chemical Property - a characteristic that indicates the ability of a substance to form another substance, this cannot be determined just by observing or touching the substance,
                                 - ex. Heat Combustion
c. Intensive Property - a property of matter that is dependent of the quantity of the substance but depends on the kind of matter
                                - ex. Density, boiling and melting point, specific gravity
d. Extensive Property - depends of quantity of a substance
                                 - ex. Mass, Volume

Changes of Matter
a. Physical Change - a change in physical property that retains the identity of the substance: a change in size, or a change in shape or in appearance or state
                               ex. water boiling, water freezing, sugar dissolving in water
b. Chemical Change - a change in which the original substance is converted to one or more new substances
                                - ex. paper burns, iron rusts, silver tarnishes

Science and its branches

Science (from the Latin scientia, meaning “knowledge”) - is an organized body of knowledge about the natural universe and the processes by which that knowledge is acquired and tested.

1. Social Sciences - deal with human society and individual relationships

1. Natural Sciences - investigate the natural universe.

• Biological Science (also called "Life Science") - the study of living matter
• Physical Science - the study of nonliving matter.

5 Major Divisions of Physical Science

• Physics, the most fundamental of the divisions, is concerned with the basic principles and concepts of matter and energy.
• Chemistry deals with the composition, structure, and reactions of matter.
• Astronomy is the study of the universe, which is the totality of all matter, energy, space, and time.
• Meteorology is the study of the atmosphere, from the surface of the Earth to where it
• ends in outer space.
• Geology is the science of the planet Earth—its composition, structure, processes, and history.
