Science From Small
Large It's all... More than you think... Chemistry An atom is the smallest
thing in science. It contains a nucleus and
multiple protons, netrons
and eletrons A nucleus is located
inside a atom in the
middle. It also has a positive charge. A proton has a positive
charge. It's located in the
nucleus... And is used to
count the atomic
number. An electron has a
neagative charge. It also surrounds
an atom. A neutron is located
in an atom. It has a negative charge. Genetics Genetics is the study of
how traits are inherited
thorugh the action of
alleles. Hereditary is the
passing of traits
from parents to
offspring. A hybrid is an offspring
that was given different
genetic information for
a trait from each
parent Dominant describes a
trait that covers over
or dominant another
form of that trait. Recessive describes a trait
that is covered over or
dominated by another form
of that trait and seems to
disappear. Body Systems Systemic circulation is the
largest part of the circulatory
system. It has oxygen rich
blood... And it also flows
to the organs and
body tissues excluding
the heart and lung. Pulmonary circulation is the flow
of blood through the heart and
back to the heart. Coronary circulation is the
flow of to and from the
tissues of the heart. Plasma is the liquid part of blood. It makes up more
than half of blood
and is made of
mostly water.
Nutrients, minerals, and oxygen
are dissoulved in the plasma so
that they can be carried to
body cells Waste is also
carried in the
plasma. Platlets are irregularly shaped
cell fragments that help clot
blood. Physics Temperature is the
measure of the kinetic
energy of the atoms of'
an object. Kenetic Energy is energy
an object has due to it's motion. Potential Enerygy is energy an object
has due to it's motion. Energy is the ability to cause change. Law of conservation of energy
states that energy can not be
created of distryed, but can
only be transformed from
one form to another. It can change the speed, direction, shape or temperature of an object. Weathering/Erosion/Deposition Weathering is mechanical or chemical surface process that break rocks into smaller and smaller pieces Mechanical weathering is the physical process that breaks rocks apart without changing theis chemical makeup Chemical weathering occurs
when chemical reactions dissolve the minerals in rocks or change them into different minerals. Erosion is the process in which surface
materials are worn away and transported
from one place to another by agents such
as gravity, water, wind, and glaciers. Deposition is the dropping of sediments that occurs when agent of erosion, such as gravity, a glacier, wind, or water, loses it's energy and can no longer carry it's load.
It can be caused by ice wedging, animals, and plant roots. Ecology Ecology is the study of interactions
that take place among organisims and
their enviroment. An ecosystem is all the living
organisims that live in an area
and the nonliving features of
their enviroment. A population is all
the organisims that belong to the same
species living in a
community. Habitat is a place where
an organisim lives and that
provides the types of food,
shelter, moisture, and
temperature needed for
survival. Population is all the oganisims
that belong to the same species
living in a community. http://www.mghs.sa.edu.au/Internet/Faculties/Science/Year10/Pics/ecosystem.jpg http://www.wcskids.net/shhs/clubsorgs/ecology1.gif http://www.bcssa.org/newsroom/scholarships/great8sci/Photos/Earth_Photos/Chemical_Weathering.jpg http://grandbaynerr.org/images/Erosion_site03.Grand_Battures.20041201.detail_of_land_slumping.2.jpg http://img.hisupplier.com/var/userImages/old/estarelectronic/estarelectronic$21894844.jpg http://www.enwin.com/

followed by Earth as it
moves around the Sun Solstice is the time
when the Sun reaches
it's greatest distance
north or south of the
equator. Equinox is a twice-yearly time when
the Sun is directly above the eqator
and the lenth of the day equals the lenth
of night worldwide. Lunar Eclipse occurs during a
full moon, when the Sun, the Moon,
and Earth line up in a specific way
and the Moon moves into the Earths
shadow. Solar Eclipses occurs during a new moon, when the Sun, the Moon, and Earth are lined up in a specific way and Earth moves into the Moon's shadow. http://www.cealagar.com/wp-content/uploads/2009/07/july-2009-solar-eclipse-images-live-stream-online.jpg
