reproduce
to make more of the same kind of organism
trait
a characteristic that an organism has (exp. pine trees have needles, zebras have stripes)
inharit
the way an offspring (or baby) gets a trait from its parent (note: plants and animals inherit traits from their parents)
life cycle
the stages a plant or animal goes through
lief span
how long an organism lives
grow
to increase in size
develop
to change from one life cycle stages to another
egg
an oval object laid by some animal from which offspring hatch
larva
the life cycle stage that comes after egg and before pupa
pupa
the life cycle stage that comes after larva and before adult
adult
a mature organism
roots
the parts of the plant that grows underground and takes in water and nutrients; they also help hold the plant in the ground
leaves

flower
the part of the plant that makes seeds
seed
the product of a flower which contains an embryo (from which a new plant can grow)
fruit
the part of the plant that contains seeds
germination
when a seed begins to sprout or grow
photosynthesis
the way plants make food by using water, carbon dioxide, and sunlight
mature plant
an adult plant that can make flowers and seeds
shelter
a place that protects or covers an organism
nutrients
any substance that plants or animals need to live and grow (such as; minerals, vitamins, food)
food
it supplies the energy for organisms tp grow and heal themselves
rotating
when the Earth spins on its axis (it takes the Earth one day or 24 hours to rotate once)
revolving
when the Earth orbits around the Sun (it takes one year or 365 days)for the Earth to revolve once

precipitation
rain, snow, sleet, or hail
runoff
water flowing on the Earth
groundwater
water under the ground
erosion
the wearing away of earth
deposition
when pieces of earth are moved from one place to another
matter

three state of matter
it can be gas, liquid, or solid
solid
has definite shape, volume, and mass
liquid
it flows and takes the shape of the container it is in (liquid has a definite volume and mass)
gas
it spreads out to fill the container it is in
properties

mass
the amount of matter in n object
gram
metric unit of mass
volume
the amount space matter takes up
milliliter

heat
moved from warm matter to cool matter
temperature s
how hot (or cold)matter i
closed circuit

conductor
an object or material that allows electricity, heat, or sound to move through it
insulator
an object or material that does not allows electricity, heat, or sound to move through it
force
a puch or a pull
gravity
a force that pulls objects towards the centers of the Earth
friction
the force that stops or slows down or stops movement
magnetism
the force exerted by a magnetic field
experiment
