| A | B |
|---|
| Stationary Front | doesn't move and causes flooding or blizzards,  |
| Wind Vane | tells the direction the wind is going,  |
| Anenometer | Tells how fast the wind is going,  |
| Asteroid Belt | a band of rocks between Mars and Jupiter and is the boundary between the inner and out planets,  |
| barometer | tells the pressure or weight of the air,  |
| Cold front | This brings bad weather like tornadoes, thunderstorms, and blizzard conditions,  |
| compound machine | more than one simple machine working together to complete a task; an example would be a pencil sharpener,  |
| Rotation | how long a planet takes to make one complete 360 degree spin on its axis; Earth has a 24 hour day because of this.,  |
| high pressure | sunny days,  |
| incline plane | can be a ramp, stairs, or even a screw; the mechanical advantage increases as the length of the ramp increases,  |
| inner planets | Mercury, Venus, Earth, and Mars,  |
| isobars | the closer the lines are together the windier it is outside,  |
| Elliptical orbit | an oval orbit caused by the planets wanting to travel in a straight line until the Sun pulls them back,  |
| lever | made up of a stiff rod and a fulcrum; the closer the fulcrum is to the object being moved the more mechanical advantage it has,  |
| life of a star | sun is an average planet and all things start as nebulae,  |
| low pressure | tends to lead to rainy cloudy conditions,  |
| mechanical advantage | how much easier a job is made by using a simple machine,  |
| phases of the moon | moon gets its light from the Sun as reflected off of it; a new moon is directly in between the Sun and Earth so we can't see it; waxing is getting bigger and waning is getting smaller,  |
| Nake Eye Planets | the planets we can see without the use of a telescope,  |
| Gas Giants | the outer planets that are primarily made of gases,  |
| Revolution | how long it takes a planet to orbit the Sun one time; Earth is 365.25 days,  |
| seasons | caused by the tilt of the Earth on its axis; summer and winter are actually at the far ends of the ellipse,  |
| rain gauge | used to measure how much rain has fallen,  |
| Solar System | made of the planets and one star, the Sun; make sure to know the order of planets,  |
| telescope | used to see things at great distances,  |
| thermometer | measure changes in temperature; 32F is freezing 212F is boiling,  |
| warm front | rain and drizzle or snow,  |
| wedge | a sharp object that is meant to go through things; examples include knives, nails, and axes,  |
| wheel and axle | the bigger the difference between the width of the wheel and the axle the more mechanical advantage it has,  |
| condensation | water vapor cools and becomes drops of water on colder objects or make clouds,  |
| decomposers | things that take dead matter and send it back into the ground as nutrients to make the soil richer,  |
| consumers | animals and plants that aren't green and can't make their own food,  |
| evaporation | liquid water heats up and the atoms start o spread apart and become a gas,  |
| humidity | amount of water vapor in the air; the higher the humidity the closer the clouds are to raining,  |
| producers | green plants that make their food from the Sun and Carbon dioxide,  |
| precipitation | rain, snow, sleet, and hail,  |
| scavengers | consumers that eat dead animals; vulture and hyenas are examples,  |
| constellations | a group of stars that make a picture in the sky; an example would be the constellations of our horoscope,  |
| research question | the first step in the research or experimental process; without this you don't really have a reason to do the experiment |
| hypothesis | your best informed prediction about what will happen in an experiment |
| observations | observations always occur while you are doing the experiment; they can be sounds you heard; pictures you took; or notes about what was happening |
| Testing | when doing an experiment you can only change one thing each time you redo the experiment; this is the only way you will know if it made a difference or not |
| pulleys | involves a round object and a rope; the more pulleys the more mechanical advantage,  |
| Brightest object in sky | planets are the brightest objects in the sky because they are closer to the Earth than any stars,  |
| action and reaction | for every force in one direction there is an equal and opposite reaction in the other direction; gravity,  |
| friction | all MOVING objects have this pushing against their forward movement,  |
| invasive species | any species that doesn't belong in an ecosystem and cause the food chain to be changed,  |
| mimicry | looks like something else that is dangerous even though it isn't,  |
| warning coloration | bright colors that let predators know that they are poisonous,  |
| behavioral adaptation | a behavior like living in packs or migrating that helps the animal survive,  |
| transparent | light goes straight through it and you can see clearly through it; glass,  |
| translucent | light is bent while going through it causing things to appear unclear or blurred like pool water or stain glass windows,  |
| opaque | light can not get through it; light reflects back off it like a mirror,  |
| refraction | the bending of light that can create a rainbow when going through a prism,  |
| reflection | light can not go through so it bounces off the object like a ball,  |
| climate | related to where you are on relations to the equator; this would be the normal temperature and rain patterns you would expect from year to year not day to day like weather,  |
| vibrations | sound travels by using vibrations; it needs a type of matter (solid, liquid, or gas) to vibrate through; there is nothing in space for sound to travel through,  |
| atmosphere | protective layer of gases around a planet that keep or break down meteors so they don't hit the planet; planets have to have enough gravity to hold atmosphere; lots of craters indicate the planet doesn't have much of an atmosphere,  |
| adaptations | things that occur to a species between generations that help it SURVIVE,  |
| CAMOUFLAGE | physical adaptation,  |
| ecosystem | all the animals and plants of an area; includes climate; a lot like dominoes so if one species is hurt by human pollution they all are,  |
| weather map | includes all the different measurements used by meteorologists to make predictions about DAY TO DAY weather,  |
| gravity | the force of attraction that all types of matter have; the bigger the object the more gravity it has; helps to explain why certain planets have so many moons,  |
| big instruments | make a very low sound,  |
| small instruments | make a very high sound |
| tightening strings or covers on drums | the more tension or tighter it is the HIGHER the sound,  |
| scientific method | question, hypothesis, experiment and observation, results, report,  |
| pitch of a sound | how high or low a sound is; the closer the waves are together the higher the sound,  |
| amplitude | the loudness or volume of a sound; the bigger the waves the louder the sound,  |
| example of convex lens | magnifying glass because it makes things bigger; the middle of the lens bubbles out like a drop of water,  |
| convex and concave lens | convex lens have the thickest part in the middle and concave lens have the thickest parts on the outside; effects whether things are bigger or smaller,  |
| Concave mirror | reflects things back at you upside down like a spoon; this is how we see things upside down,  |
