Safety Rules Conduct yourself in a responsible manner at all times in the laboratory. A set of instructions that if followed will keep you safe.

Safety symbols Designed to warn about hazardous materials or locations.. Visual shapes and pictures are used.

Graduated cylinder Is a piece of laboratory equipment used to accurately measure the volume of an object. Water displacement can be used to find out the volume of an object. Graduated cylinders are generally more accurate and precise for this purpose than flasks

Metric System An international decimalised system of measurement, first adopted by France in 1791, that is the common system of measuring units used by most of the world. It...

balance A lab instrument used to measure mass. Can be electronic or a triple beam

mass A body of matter with no specific shape

flask A small container, such as a bottle, having a narrow neck and usually a cap.

Spring scale A scale which measures weight by determining the deflection of a spring

volume Is how much three-dimensional space a substance or shape occupies or contains, often quantified numerically using the SI derived unit, the cubic meter.

graph A visual display of data for quick review.

problem The first step in the scientific method and is written in the form of a question.

Gather data Using the internet, books, journals, libraries, and interviews to increase knowledge.

materials What is needed to conduct the experiment.

conclusion The final step in the scientific method and is a final statement.

infer To make a quick decision based what your senses are telling you.

Independent variable s that variable presumed to affect or determine a dependent variable. It can be changed as required, and its values do not represent a problem requiring explanation in an analysis, but are taken simply as given.variabledependent variable

Dependent variable In any true experiment, a researcher manipulates an independent variable, to influence a dependent variable, or variables.

Theory A statement that has some data to support it but there is still reason not accept it as fact. Big Bang Theory Darwin’s Theory Plate Tectonic Theory Natural Selection Theory Einstein's Theory of Relativity

law It can not be disproved and has stood the test of time. It is a fact.

Control variable All the things in an experiment that is kept the same throughout.
