Do You Know What Matter Is?
Matter is any thing that takes up space and has mass. Matter also has
properties. A property is a characteristic that you
can observe about matter. This includes color, texture, size,
shape, and hardness. Mass is the amount of
matter in a object. Matter is measured in
grams.
Buoyancy
Do you know what buoyancy is? Buoyancy is the up ward force of water or other liquids
Solid
A solid is matter with a definite size and shape. A solid also takes up a
definite amount of space. The particles of a solid
are packed tightly together.
Liquid
Do you know what a liquid is? A liquid has no
definite shape ( takes the shape of container) has a fixed or definite amount.
It's particles are more free than a solid an moves very slowly
Gas
Do you know what gas is? Gas has no definite shape and no definite size. Gas's particles moves VERY fast and
free.
Area
Do you know what area is? Area is the number
of square units that covers a surface. The
formula of area is length x width. The red
squares are an example of area.
Perimeter
Do you know what a perimeter is? The way
you can get a perimeter is add 4 all sides. The
blue arrows are an example perimeter.
Volume
Volume is how much space an object takes up.
To get a volume you multiply
lengthxwidthxhieght.
Weight
Do you know what weight is? Weight is
measure of the pull of gravity on an object and
you can measure it in newtons and pounds.
The three R's
Did you know that there's something called the
three R's. The R's stand for reduce, reuse,
recycle.
Density
Density is the amount of mass in a given space. If you have a 15 gram cup and a 20 gram cup and each one has 12 grams
of paper in it the 15 gram cup has more density.
Elements
Elements are the building blocks of matter. They
are made up of only one type of matter. Gold,
silver, and oxygen are some examples of
elements. The periodic table sorts the elements
by properties.
AtomsAtoms are the smallest
particles of an element. Atoms of one element are
all alike. Atoms have a nucleus, protons,
neutrons, and electrons. Protons and neutrons are
inside the nucleus. Protons have a positive
charge and can't leave its atom. Neutrons have no charge. Electrons have a
negative charge .they travel in a cloud outside
the nucleus.
Mixture
A mixture is two or more types of matter
combined but are not blended entirely
together. Mixtures can be separated by sorting
or picking, a filter, or evaporation. Some examples are mixed
vegetables, salt water, and grape juice.
Compound
A compound forms when two or more matter are combined chemically. Each element loses its
properties when combined.
Alloy
A mixture of two or more elements one must be
metal. Mixing metal with another element can
make it stronger.
Physical Change Physical changes begin and end with the same type of matter. Heat
energy and loss of heat energy causes matter to change state. The mass of the object stays the
same. Matter can change in size/shape,
change in texture, change in position, and
change in state.
Chemical Change
A chemical change has different properties than the matter you started with. You start with one
matter and end with another matter. Chemical change
involves energy either takes in or gives of energy. Penny +
vinegar= copper acetate.
