MatterBy Brooke Elwell:)
I am Persnickity the Perfectly Perfect Panda. I am perfect at
all smarts. Today I will help you to learn about matter! Think about this while you learn: Matter matters! Why does matter matter? I will help you learn throughout
this presentation.
Matter is anything that takes up space and has mass. The three states
of matter are solids, liquids, and gases.
Matter also has properties. Properties are characteristics of something you can
observe. Examples of properties are color, texture, shape, size,
buoyancy, and hardness.
What is matter?
What is mass?It doesn't matter if it's a solid, liquid, or a gas, it
all has mass. Mass is the amount of matter making
up an object. Mass is measured in grams or
kilograms, depending on the size of the object. You would measure object on a balance pan with known
masses.
This is a balance pan. I am showing
how you would measure mass.
I am measuring my earbuds. I start with 50 grams, and that was
way to heavy. I kept trying out known masses and eventually came out with
11 grams.
Area
Area is the amount of square units that it takes to cover a surface. Area is measured in square inches, centimeters,
yards, etc. To find the area of an object, you would calculate the LengthxWidth. This is how you would find area.
VolumeVolume is the amount if space an object
takes up. You can calculate volume using LengthxWidthxHeight.
AtomsThe atoms of one element are all alike. They are the smallest particles of an element. Each atom has special parts to it. The nucleus is the center. Inside the nucleus are protons and neutrons. There are always the same amount of neutrons as protons. Outside of the
nucleus is a cloud. There are two shells to the cloud. The inner cloud can only have two electrons whereas the outer
shell can have up to eight electrons. To make an atom balanced, there will be
the same amount of protons, neutrons, and electrons. To make an atom
electrically charged, you would add more electrons because you can't take
away protons. To make an atom positively charged you will take away
electrons. On the periodic table elements are organized by their state
of matter and by the number of protons. For example hydrogen has 1
proton so it is the first element.
Elements
Elements are the building blocks of matter. They are made up of only
one type of matter. Examples of
elements are gold, silver, and oxygen. Elements are made
of atoms.
Mixture
A mixture is two or more types of matter
combined. Each type keeps its original
properties. Examples of a mixture are mixed
vegetables, salt water, and grape juice. A
solution is a mixture too, but it is blended
completely. A mixture or solution can be separated
by picking, filter, or by evaporation.
CompoundA compound is when two or more types or
matter combine chemically. All
elements combined in a compound lose
their properties when combined. Examples are salt, sugar, and
rust.
Alloy🏆An alloy is a mixture of two or more elements-
one must be metal. Mixing metal with another element
makes it stronger. For example, you would mix pure gold with
another metal to make it stronger that pure
gold.
Physical change
A physical change begins and ends with the same
type of matter. In a physical change, the mass stays the same. There are four types of physical changes. There
are changes in size and shape, change in texture, change in position, and change in state. Heat
energy and the loss of heat energy causes matter to
change state. 🚿
Chemical Change
A chemical change is when matter changes
itself. It always involves energy. You start with one
type of matter and end with another. An example of a chemical change is
copper acetate. It always involves energy.
