astronomy

the study of stars and hevenly bodies to learn more about them

astrology

the study of stars to predict the future

rotation

the act of rotating as if on an axis

revolution

when a hevenly body goes around anthor hevenly body

star

a ball of hot glowing gas

our nearest star

SUN

SUN

93 million miles away. light from sun reaches Earth in 8 minutes medium star

three ways a star is medium

size, temperature, and age

stars give off

heat, cosmic rays, x rays, light, energy, ultra violot rays, and radio waves

2 ways telescopes help study stars

stars are brighter and more stars are seen.

obsevatory

a domed shapes building with a telescope to study real stars

plantarium

a domed theater with a projector for studing fake stars

radio telescope

a telescope that picks up radio waves from very different stars

double star ( binary star)

2 stars that orbit each other and look like one

cepheid ( regular varible)

a star that changes from bright to dim in a pattern

nova

a star that suddenly becomes thousand of times brighter

super nova

a star that suddenly gets very bright and explodes

thermocouple

an instument used to find the temperature of stars

spectroscope

an instrument that uses a prism to find the elements of a star

constellation

A group of stars that appear to form a picture in the sky

nebula

a large cloud of dust and gas in space

star cluster

a group of hundreds or thousands traveling together in space

Two types of nebula

bright and dark

examples of a bright nebula

crab, orion, butterfly, and the witches hat

examples of a dark nebula

horse head, colsack, cone, and the tower

two types of star clusters

open and globular

examples of a open star cluster

pleiades, beehive kids and the jewel box

examples of a globular star cluster

M13

Galaxy

a group of billons of stars, planets, nebule, and dust

three types of glaxies

spril, elipical, and irrelgular

our nearest glaxy

Andromedia

Universre

All the glaxiers and the space in between them

the big band theroy

A mass of matter blew up. this crreated the glaxies. they are still moving away from each other today.

cell

the smallest part of a living thing

cell wall

the rigid structure that gives plant cells their shape.

cell membrane

the thin layer that hold the cell together and lets substances in and out of a cell

cytoplasm

the watery gel inside a cell that holds the various parts

nucleus

center of the cell contols activites

chromosones

structures that hold the DNA inside the nucleus

vacuoles

spaces in the cytoplasm that store food and water

mitocondria

structures that release energy from food

chloroplasts

green parts in a plant cell that contain chlorpphyll

chlorophyll

the green sustance that plants use to make food.

protist

a large group of mostly single celled organisms that have traits of animals, plants, or both

protozoa

protists with animal like traits

algea

protists with plant like traits

the amoeba facts

protozoan
lives in fresh water
no definate shape
no front or back
neither male nor female
3 d

the amoeba can

move with falsefeet ( pseudopod)
eat surronds it food
reproduce dividing
breath cell membrane
respondes to things food and light
eliminates waste cell membrane

the paramecium facts

protozoan
lives in fresh water
definate shape
front or back
neither male nor female
3 d

the paramecium can

move with cilla
eat mouth
reproduce dividing
breath cell membrane
respondes to things food and light objects in its way
eliminates waste anal pore

the euglena facts

protist
lives in fresh water
definate shape
front or back
neither male nor female
3 d

the euglena can

move flagellum
makes food clorplasts
eats with gullet
uses eyspot find sunlight
reproduces mitosis

sybiosis

a close relationship between two species that helps at least one of them

three types of sybosis

mutualism commesalism parasitism

mutualism examples

both are helped cleanerwrasset and bigger fish

commesalism and examples

one is helped and the other not affected orchid and tree

parasitism

one is helped and the other is harmed ticks

parasite

an organism that lives in or on another organism to get food and harms it

host

the organism that is providing food for the parasite

monerans

one celled organisms without a necleus

bacteria

monerans that feed on living things or dead materal

three kinds of bacteria

rod spiral sherical

blue-green bacteria

monerans that contian chorophyll that makes its own food

bacteria reproduce by

fission

virus

tiny bit of genitc materal wrapped in a capsule of protein

immune system

body's system of defense against disease

communicable desease

a disease that passes from one host to another bty direct or indirect contact

toxins

chemical posins harmful to the body

antibodies

protiens that attach to bacteria and virusand destroy them

antibotic

medicine that stops the reproduction of bacteria

vaccine

a mixture of dead or weakend microbes that causes the body to produce antibodies

tissue

similar cell grouped together

organ
