Tools Life Scientist

Compound Light Microscope Consists of a tube with lenses, and a light source - it magnifies the image
Electron Microscope Tiny particles of matter are used to magnify images
Transmission Electron Microscope Electrons pass through the specimen and produce a flat image - can magnify up to 200,000 times the actual size
Scanning Electron Microscope Electrons bounce off the surface of the specimen and a three-dimensional [3-D] image is produced - can magnify up to 100,000 times the actual size
X-Rays Used for almost a century to see internal structures of organisms [bones, heart, lungs] and the structures of proteins
CT Scans [Computerized Tomography] Low dosage x-ray beams are passed through the body at different angles, and often a dye is injected to help highlight tissues - provides a clearer, more detailed image than x-rays - useful for studying brain and spinal tissue
MRI [magnetic resonance imaging] provides a clearer image than x-rays by using short bursts of magnetic field - useful for studying brain and spinal tissue
Computers Can collect, store, organize, and analyze information - can create graphs, solve math problems, and analyze data - With the help of computers, life scientists are able to solve problems that they weren't able to solve in the past
Graduated Cylinder Measures the volume of liquids - basic unit is liter
Thermometer Measures how hot or cold an object is - basic unit is degree
Balance Measures the mass of an object - basic unit is kilogram
Meter Stick Measures the length of objects - basic unit is meter
Metrics The SI unit of measurement based on the number of ten
Length How long an object is - basic unit of length is the meter
Volume The amount of space an object occupies Liquid is measured in Liters Solid objects are measured in cubic meter [m3] or cubic centimeters [cm3]
Mass The amount of matter in an object - basic unit of measure is kilogram
Calorimeter Instrument used to measure heat Heat isn't measured with thermometer
Kelvin Official SI unit for temperature
Joules Unit of measure for heat
Degrees Unit of measure for temperature
Technology The application of science for practical purposes, the use of tools, machines, materials, and processes to meet human needs
