Science Intro 1st Test Review

A complete set of vocabulary flashcards covering basic lab safety symbols, metric conversions, scientific notation, experimental variables, data types, and graphing.

WHMIS

Workplace Hazardous Materials Information System, a standard system used primarily in workplace environments to classify and label hazardous chemical products.

HHPS

Hazardous Household Product Symbols,

Diffrence of HHPS AND WHISM

Whisms are deisgned for the workplace and industrial materials, while HHPS is deisgned for consumer products used at homes.

Flammable Label

A hazard symbol indicating that a substance can easily catch fire and burn when exposed to a spark or heat source.

Corrosive Label

A hazard symbol indicating that a material can chemically destroy or burn skin, eyes, or other physical materials upon contact.

Oxidizing Label

A hazard symbol indicating that a chemical releases oxygen, which can feed a fire and cause other combustible materials to burn more readily.

Explosive Label

A hazard symbol indicating that a substance can rapidly detonate or explode if exposed to heat, shock, or pressure.

Lab Symbols

Safety pictograms placed in laboratory environments or manual procedures to warn against specific hazards or detail required protective gear.

Metric Conversions

The mathematical process of converting between different units within the metric system by moving decimal places or multiplying/dividing by powers of $10$.

Scientific Notation

A method of writing very large or very small numbers using powers of $10$, written in the standard form $a \times 10^n$ where 1 \break \neq 0.

Independent Variable

The factor in an experiment that is intentionally manipulated or changed by the researcher to test its effect.

Dependent Variable

The factor in an experiment that is measured or observed, which changes in response to the manipulation of the independent variable.

Hypothesis

A proposed, testable explanation or prediction for an observation, often structured to show how changing the independent variable affects the dependent variable.

Quantitative Data

Data and observations that are expressed as numerical measurements, quantities, or counts.

Qualitative Data

Descriptive data and observations that focus on non-numeric qualities, physical properties, or characteristics.

Types of Graphs

Visual diagrams—such as line graphs, bar graphs, pie charts, and scatter plots—used to organize, display, and analyze relationships between variables.
