### 7th Grade Science Exam 1 Mr Barrett

List 5 Dos for working in a science lab 1 WEAR GOGGLES 2 HAIR BACK 3 GLOVES 4 CLOSED TOE SHOES 5 RESPONSIBILITY
Independent Variable THE PART OF THE EXPERIMENT YOU CHANGE ON PURPOSE
Dependent Variable THE CHANGE THAT OCCURS AS A RESULT OF THE CHANGE MADE FOR THE INDEPENDENT VARIABLE
Constants A FACTOR IN AN EXPERIMENT THAT DOES NOT CHANGE EX: ON THE DECAY OF A FRUIT AN APPLE WOULD BE THE CONSTANT
Control Group A GROUP USED AS A BASELINE FOR CHECKING AND CMOPARING THE RESULTS OF AN EXPERIMENT EX: GIVE SOMEONE A SUGAR PILL AND SOMEON AN ENERGY PILL
Quantitative Observations/Data DATA THAT DEAL WITH NUMBERS AND MEASUREMENTS EX: IN A FIRST GRADE CLASS THERE ARE 12 BOYS AND 9 GIRLS
Qualitative Observations/Data DATAT THAT CAN BE COLLECTED WITHOUT TOOLS BY USING 5 SENSES EX: TOUCH, SEE, SMELL, TASTE, HEAR
Repeated Trials ADDITIONAL TRIALS OR TEST OF THE SMAE EXPERIMENT EX: 2 + 2 = 4 CHECK ON A CALCULATOR
How to write a hypothesis AN "IFâ€¦.THEN" STATEMENT EX: IF WE GO WHILE IT'S RAINING THEN WE WILL GET WET
How to write a title THE EFFECT OF IV ON DV
Y axis: Which variable goes on it and what direction is it? THE DEPENDENT VARIABLE VERTICALLY
X axis: Which variable goes on it and what direction is it? THE INDEPENDENT VARIABLE HORIZONTALLY
Permeable MATERIAL THAT LIQUIDS CAN FLOW THROUGH EX: SPONGE
Impermeable MATERIALS THROUGH WHICH LIUIDS CANNOT SOAK/FLOW EX: CONCRETE, CEMENT/PUDDLE
Which material (clay, sand, or gravel) will hold the most water? GRAVEL
Accumulation THE PROCESS OF WATER GATHERING IN A RESERVOIR
Transpiration WATER VAPOR GIVEN OFF BY PLANTS AND ANIMALS
Which reservoir in the water cycle contains the most water? CONDENSATION
Condensation THE CHANGE FROM GAS TO LIQUID EX: WHEN STEAM TURNS INTO RAIN/DEW
What are you seeing when the mirror fogs up after you breathe on it? EVAPORATION
Percolation THE MOVEMENT OF WATER THROUGH EARTHS MATERIALS EX: GRAVEL/SOIL/CLAY
Aquifer PERMEABLE EARTH MATERIALS THAT COLLECT WATER EX: THE DICKSON RIVER
Aquitard IMPERMEABLE EARTH MATERIALS EX: CLAY: NOTHING CAN GET THROUGH IT
Pesticides CHEMICALS TO KILL INSECTS EX: INSECTICIDES, FUNGICIDES, HERBICIDES
Point-source pollution SINGLE, INDENTIFIABLE SOURCE OF AIR, WATER, THEMAL, NOISE OR LIGHT POLLUTION EX: AIR OR CERTAIN COMPANY MAKING CHEMICALS
Non-point source pollution BOTH WATER AND AIR POLLUTION FROM DIFFUSE SOURCES EX: AIR: PEOPLE THAT DRIVE CARS
Ecosystem SPECIES COMING TOGETHER WITH IT'S ENVIRONMENT, LIVING AND NON-LIVING EX: DESERT: ALL ORGANISMS DESIGNED TO SURVIVE WITH LITTLE WATER
Biotic Factor LIVING THINGS IN AN ECOSYSTEM EX: BIRDS/ HUMANS/ ANIMALS
Abiotic Factor NON-LIVING PARTS OF ECOSYSTEM EX: TABLE CHAIR PAPER
Niche IT PROVIDES MANY DIFFERENT NICHES FOR ORGANISMS THAT LIVE UNDER / ON THE CORALS
Population ALL OF THE INDIVIDUAL OF ONE SPECIES IN A SPECIFIED AREA A TONE TIME EX: BEEHIVE
Community ALL THE INTERACTING POPULATIONS AND/OR INDIVIDUALS IN THE SPECIES AREA, MORE THAN ONE SPECIES EX: OWL AND BIRDS
In which biome would it be an advantage to have white fur? TUNDRA
Tundra ICY, COLD CLIMATE, FREEZING (LITTLE SNOW)
Taiga/Boreal Forest COOL 40-1100 CM RAINFALL ALL YEAR
Temperate Deciduous Forest LOTS OF TREES HOT /DRY
Grasslands VERY HOT IN SUMMER DRY AND VERY COLD IN WINTER
Tropical Rainforest HOT, MOIST 100 CM RAIN PER YEAR
Direct Observation A METHOD OF COLLECTION DATA THAT INVOLVES FIRST HAND VISUAL INSPECTION OF THE PARAMETERS UNDERSTUDY EX: YOU SEE 5 APPLES, YOU COUNT 5 APPLES, THERE ARE 5 APPLES
Indirect Observation THE RESEARCHER MUST RELY ON REPORTED OBSERVATIONS THAT INCLUDE DIRECT OBSERVATIONS OF OTHERS EXL ASKING SURVEYS
Sampling COUNTING THE NUMBER OF ORGANISMS EX: A CORAL REEF HAS MANY ORGANISMS
How populations increase WHEN THE BIRTHRATE EXCEEDS DEATHRATE EX: WHEN A MOUSE RATE GOES DOWN AN OWLS RATE GOES DOWN AS WELL
How populations decrease WHEN DEATH RATE EXCEEDS BIRTHRATE EX: WHEN A MOUSE RATE GOES UP AND OWLS GOES UP THE MOUSE GOES DOWN
Limiting Factor THE GROWTH OF AN ORGANISM POPULATION EX: SPACE - THE POPULATIONCAN ONLY GROW WITHIN ITS ROOM
Jet Stream A NARROW, VARIABLE OF VERY STRONG AIR CURRENTS CIRCLING THE GLOBE 5-9 KILOMETERS
Density THE DEGREE OF COMPACTNESS OF A SUBSTANCE EX: IF OIL GOES INTO THE OCEAN IT RISES BECAUSE OF IT'S LESS DENSE THAN WATER
What causes warm air to rise? TEMPERATURE, WIND, AND DENSITY EX: WHEN MOLECULES ARE HEATED THEY COME TOGETHER AND RISE
Gulf Stream A WARM OCEAN CURRENT THAT FLOWS FROM THE FULF OF MEXICO THROUGH THE ATLANTIC OCEAN
Habitat Destruction/Loss WHEN A NATURAL HABITAT IS RENDERED FUNCTIONALLY UNABLE TO SUPPORT THE SPECIES PRESENT EX: WHENA FOREST FIRE HAPPENS THEN A TREE FALLS A SQUIRREL LOOSES IT'S HOME
Habitat Fragmentation DESCRIBES EMERGENCE OR DISCONTINUES IN AN ORGANISM PREFERRED ENVIRONMENT EX: WHEN ANIMALS ATTACK EACH OTHER
Extinction THE STATE/PROCESS OF A SPECIES FAMILY OR LARGER GROUP BEING OR BECOMING EXTINCT. EX: DINOSAURS WENT THROUGH AN EXPLOSION AND GOT KILLED
Keystone Species OTHER SPECIES IN AN ECOSYSTEM LARGELY DEPEND SUCH THAT IF IT WERE REMOVED THE ECOSYSTEM WOULD CHANGE EX: IF YOU TOOK A BIRD OUT OF A WHOLE SPECIES THEN IT WOULD ALL CHANGE
3 Factors that Affect Biodiversity 1 HABITAT DESTRUCTION 2 CLIMATE CHANGE 3 POACHING EX: 1 LOOSING HOMES 2 PLANTS IN COLD EATHER WON'T GROW 3 ELEPHANTS AND TUSKS
Captive Breeding BREEDING ANIMALS IN HUMAN CONTROLLED ENVIRONMENTS WITH RESTRICTED SETTINGS EX: MAKING A BIGGER POPULATION
Biodiversity THE NUMBER OF A DIFFERENT SPECIES IN AN AREA EX: POPULATION/ECOSYSTEM
What is the MAIN cause of species extinction? (Be specific!) POACHING/ILLECAL HUNTING EX: ELEPHANTS FOR TUSKS AND ALLIGATORS FOR SKING
What type happens after a forest fire? BURNS LOW-LYING VEGETATION
Pros and Cons of forest fires 1 RECYCLES NUTRIENTS INTO SOIL 2 HELPS CONTROL DISEASES IN SOIL/PLANTS 3 OPENS FOREST FOR SUNLIGHT EX: 1 ANIMAL HABITATS = RUINED 2 DAMAGE TO HOUSE.PROPERTY
Controlled burn A TECHNIQUE USED IN FOREST MANAGEMENT AND FARMING
5 DON'TS FOR WORKING IN A SCIENCE LAB 1 NO HORSE PLAY 2 HAIR DOWN 3 NO EATING OR DRINKING 4 DON'T DRINK CHEMICALS 5 NO OPEN TOED SHOES

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
