SCIENTIFIC & ENGINEERING PRACTICES
the first step of the scientific method which involves looking at or realizing something
WHAT IS AN OBSERVATION?
organisms, such as grass, that use the sun's energy to make food
WHAT ARE PRODUCERS?
female part of the flower
WHAT IS THE PISTIL?
WHAT IS PHOTOSYNTHESIS?
the amount of moisture or water vapor in the air
WHAT IS HUMIDITY?
a step in the scientific method that involves forming a question that can be tested
WHAT IS A HYPOTHESIS?
organisms such as fungi that break down and recycle nutrients
WHAT ARE DECOMPOSERS?
male part of the flower
WHAT IS THE STAMEN?
gas produced by plants
WHAT IS OXYGEN?
a tool for measuring air pressure
WHAT IS A BAROMETER?
the answer to a scientific question which is formed after data analysis
WHAT IS A CONCLUSION?
adaptations that help an organism blend into its surroundings (such as camouflage)
WHAT IS PHYSICAL ADAPTATIONS?
small leaves under the developing flower
WHAT ARE SEPALS?
the part of the plant where sugar is produced
WHAT IS THE LEAF?
tall, dark clouds associated with thunderstorms
WHAT ARE CUMULONIMBUS CLOUDS?
the testable variable
WHAT IS THE INDEPENDENT VARIABLE?
a type of adaptation such as migration or hibernation
WHAT IS A BAHVIORAL ADAPTION?
the part of the pistil on a flower that receives pollen
WHAT IS A STIGMA?
gas used by plants
WHAT IS CARBON DIOXIDE?
a boundary between two air masses that have different temperatures and levels of humidity
WHAT IS A FRONT?
the "normal" or "unchanged" group used for comparison in an experiment
WHAT IS A CONTROL?
a natural home that provides an organism with food, water, shelter, and space necessary for survival
WHAT IS A HABITAT?
plants with roots, stems, leaves, and flowers reproduce by this
WHAT ARE SEEDS?
green pigment of the leaf that absorbs sunlight
WHAT IS CHLOROPHYLL?
forms when a thunderstorm meets strong winds, causing a rotating column of air
