When a blender is used to break cells into parts.
Devices that spin thousands of times per minute.
Separating a specimen, body or cell, into its parts.
Done with a microscope and special miniaturized tools. Used to remove parts of or dissect a cell.
One cell is placed in a dish, and nutrients are supplied so that the cell can reproduce.
Used with light microscopes to highlight structures.
Adjusting a piece of laboratory equipment for accuracy in measurements.
Commonly used to collect behavioral data.
Based on glass lenses focusing a light beam, specimen in air or liquid environment, maximum power or resolution of about 1000 times
Single eyepiece to look through, keep both eyes open and keep the unfocused eye not looking through the single eyepiece.
Compound monocular light microscope
Two eyepieces to simultaneously look through, keep both eyes open, better suited for larger objects.
Stereoscopic binocular microscope
Allows higher resolution because the oil prevents scattering of the light rays that pass through the specimen.
Oil-immersion objective lens
This type of mounting of a specimen can be used to observe motion.
Based on electromagnetically focused electron beam, specimen in a vacuum, maximum power (resolution) of about 1000 times that of light microscopes.
An extremely thin slice of specimen is used. The electron beam travels through the slice.
Transmission electron microscope
Slicing is not needed. The electron beam bounces off the surface of the specimen to form a three-dimensional image of the surface.
Scanning electron microscope
A beam with pans on each end that is suspended exactly in the middle on a pivot point.
Calibrated by placing a known, calibrated mass on the balance. The balance is then adjusted so that the reading matches the mass of the sample.
Triple beam balances
Used to accurately measure volume of liquids.
Lowest part of the meniscus determines
This is the curved surface at the top of a liquid being measured in a graduated cylinder.
Pyrex beakers that can be marked for measure and or transferring fluids.
Pyrex beakers that have large base that becomes smaller towards the top, ending in narrow neck. Used to prevent spillage, good when experimenting with heat.
How close a measurement is to the true value is called...
Being able to reproduce the same measurement is called...
Include all the digits in a measurement that are known accurately and one more digit that is estimated.
Science uses this system in measurement because it is based on the decimal system, making converting between these units.
A quantity of matter.
Mass is measured in
The measure of the space a liquid occupies.
Volume of liquids
Is measured by cubic centimeters.
Volume of solids
Factors are fractions or rations of equivalent measures
1 ft =
1 inch =
Temperature, length, mass, and volume
Common measurement equipment
These are used to measure larger volumes
Used for the largest volumes to measure
Measuring small volumes
This is used in a balance beam to obtain the final balance
These are used for accurate measurements
Converting F to C is
