focuses the image under high power | Fine adjustment knob/focus |
the lighted area when looking through a microscope | field of view |
a prediction about the relationship between variables is formed from the testable question | hypothesis |
gained by carefully identifying and describing properties using the five senses or scientific tools | scientific observation |
are observations that use numbers (amounts) or measurements (including the unit label) or observations that make relative comparisons, such as more than, all, less than, few, or none | Quantitative observations |
observations that are made using only the senses and refer to specific properties | Qualitative observations |
an explanation or interpretation of an observation based on prior experiences or supported by observations made in the investigation | inference |
Each set of repeated data | trial |
a portion of the total number, as a type of estimation | sample |
extremely small particles, too small to be seen with a classroom microscope, that matter is composed of | atoms |
pure substances that cannot be changed into simpler substances | Elements |
pure substances that are composed of two or more types of elements that are chemically combined | Compounds |
not uniform throughout, the component substances can be visibly distinguished | heterogeneous mixture |
uniform throughout, the substances are evenly mixed and cannot be visibly distinguished | homogeneous mixture |
Having a shiny surface or reflecting light brightly | Luster |
Heat and electricity move through them easily | Conductors |
Ability to be hammered into different shapes | Malleable |
Ability to be drawn into a wire | Ductile |
Heavy for their size | High density |
Not shiny | Dull |
Heat and electricity do not move through them easily | Nonconductors |
Break or shatter easily (solids) | Brittle |
A horizontal row on the periodic table | period |
also called groups, are vertical columns of elements on the periodic table; they are usually numbered 1-18 | Families |
Rod-shaped bacteria | BACILLUS |
Round-shaped bacteria | COCCUS |
Spiral-shaped bacteria | SPIRAL |
The thin, flexible outer covering of a cell. It controls what enters and leaves a cell. | CELL MEMBRANE |
occurs as materials are moved from an area of higher concentration to an area of lower concentration | DIFFUSION |
Contains the genetic material (DNA) and is the control center of the cell | NUCLEUS |
Act as temporary storage centers. Some store water; others store waste products until they can be eliminated from the cell. | VACUOLE |
All organisms, including plants and animals, break down simple sugars (C6H12O6) into carbon dioxide (CO2) and water (H2O) and release energy. | RESPIRATION |
a process of cell division, which results in the production of two daughter cells from a single parent cell | MITOSIS |
A structure found in the nucleus of a cell that contains the genetic information (DNA). | CHROMOSOMES |
the passing of traits from one generation to another | HEREDITY |
a genetically determined characteristic that distinguishes one organism from another organism | INHERITED TRAIT |
the physical expression of the genes | PHENOTYPE |
responsible for the inherited characteristics that distinguish one individual from another | GENES |
Organisms rid the cells of waste products that could be harmful to the cell. | WASTE ELIMINATION |
Plants use light energy (for example sunlight) to combine carbon dioxide (CO2) and water (H2O) to make simple sugars (C6H12O6). | PHOTOSYNTHESIS |
Provides support and shape for plant cells. It is made mostly of cellulose. | CELL WALL |
Are the energy producing sites in the cell where respiration takes place. It is sometimes called the “powerhouse” of the cell. | MITOCHONDRIA |
Are the sites where photosynthesis takes place in a plant cell. They contain the chlorophyll used to make food. | CHLOROPLASTS |
The gel-like fluid inside of a cell made of mostly water | CYTOPLASM |
the diffusion of water across a membrane | OSMOSIS |
Protist with Pseudopods | AMOEBA |
Protist with Cilia | PARAMECIUM |
Protist with Flagella | EUGLENA |

covers the body and prevents the loss of water | skin |
connect the skeletal muscles to bones | tendons |
involuntary muscle that forms the heart | cardiac muscle |
involuntary muscles that control many types of movement within the body (such as digestion) | smooth muscle |
voluntary muscles attached to bones and provide the force needed to move the bones | skeletal muscle |
filter and get rid of urea, excess water, and some other waste materials released by the cells | kidneys |
tubes which connect each kidney to the bladder | ureters |
a saclike muscular organ which stores urine until it is released from the body | bladder |
tube through which urine passes before it is removed from the body | urethra |
a secondary organ to the digestive system that functions to produce digestive juices that help to further break down the food in the small intestine | pancreas |
a secondary organ to the digestive system that functions to store bile produced by the liver | gallbladder |
a secondary organ of the digestive system that produces bile, which is used by the body to break up fat particles | liver |
a short tube that stores solid waste until it is eliminated from the body through the anus | rectum |
the organ where water is absorbed from the food and taken into the bloodstream; prepares the remaining undigested food for elimination from the body | large intestine |
