ABC

A

• A is for air mass
• A large volume of air that has nearly the same temperature and humidity at different locations at the same altitude
• Maritime tropical air masses (mT), continental polar air masses (cP), ect.

B

• B is for barometer
• An instrument that measures air pressure in the atmosphere
• The barometer read 990 so we may get rain.

C

• C is for cell
• The smallest unit that is able to perform the basic functions of life
• Plants and animals are multicellular, while bacteria is unicellular

D

• D is for data
• Information gathered by observation or experimentation
• According to our data it rained ten inches this week

E

• E is for electromagnet
• A magnet that consists of a piece of iron or steel inside a coil of current-carrying wire
• Doors, cars, stereos, phones and more all have electromagnets in them

F

• F is for fulcrum
• A fixed point around which a lever rotates
• The fulcrum on the see-saw broke

G

• G is for germiantion
• The beginning growth of a new plant from a spore or seed
• We made sure the plant had the right conditions to germinate

H

• H is for humidity
• The amount of water vapor in the air
• The humidity in Rock Hill was 72% on Wednesday

I

• I is for imprinting
• Instincts that animals are born with and cannot reverse
• Baby ducks recognize the first thing they see as their mother

J

• J is for jet stream
• A wind that flows in the upper troposphere from west to east over vast distances at great speeds
• The jet stream was going 75 mph

K

• K is for kinetic energy
• The energy of motion
• The roller coaster going down the long hill has kinetic energy

L

• L is for lever
• A solid bar that rotates, or turns, around a fixed point
• Examples of levers are gardening hoes, baseball bats, crowbars, and wheelbarrows

M

• M is for magnet
• An object that attracts certain other materials, particularly iron and steel
• Refrigerators, motors, cars, cabinet latches and computers all have magnets in them

N

• N is for newtons
• the International System of Units derived unit of force
• Forece is measured in newtons on a spring scale

O

• O is for Ozonosphere
• The ozone layer refers to a region of Earth's stratosphere that absorbs most of the Sun's UV radiation
• If we mistreat our planet then we'll brake the ozone layer

P

• P is for pulley
• A wheel with a grooved rim that turns on its axle
• Blinds, car engines, and DVD trays all have pulleys

Q

• Q is for qualitative observation
• Detailed descriptions of what is seen
• Colors, shapes, and sometimes sizes are qualitative observations

R

• R is for radiation
• Energy that travels across distances in the form of electromagnet waves
• Fires radiate heat

S

• S is for spring scale
• a balance that measures weight by the tension on a helical spring
• The spring scale read 10 newtons

T

• T is for transpiration
• The movement of water vapor out of a plant and into the air
• The water from the plant traveled to a cloud and was later rained back down to Earth

U

• U is for ultraviolet radiation
• Radiation of higher frequencies than visible light
• The ozone layers protect us form these rays

V

• V is for vertabrate
• An animal with an internal backbone
• Dogs, cats, birds, and ducks are vertabrates

W

• W is for wind direction
• The direction of which the wind is blowing
• The wind direction is southeast

X

• X is for xylem
• the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem
• The xylem in the plant helped it grow big and strong

Y

• Y is for y-axis
• the secondary or vertical axis of a system of coordinates, points along which have a value of zero for all other coordinates
• The y-axis showed the inches moved

Z

• Z is for zebra
• an African wild horse with black-and-white stripes and a mane that sticks straight up
• I saw a herd of zebras at the zoo
