SAFETY GOGGLESEye protection is a priority in any science laboratory setting.

APRONUsed to protect clothing from being stained or damaged and skin from chemical burns or other irritations.

GLOVESUsed to protect hands against temperature extremes or to serve as a barrier against harmful substances.

EYE WASHUsed to rinse sediments or chemicals from the eyes. The user must bathe the eyes for several minutes.

FIRE EXTINGUISHERFire extinguishers are required safety equipment in all laboratory settings. Students may not operate these devices.

FIRE BLANKETUsed to smother flames from a fire.

FUME HOODProtect laboratory workers from fumes of potentially dangerous chemical reactions and provide a glass shield through which experiments can be clearly seen.

If you see a fire in an apparatus, or a burning liquid, it is best to put it out with

The fire blanket Water from the sinkYour coatThe fire extinguisher.

During chemistry lab two chemicals are being mixed that produce a noxious odor. Which pieces of safety equipment would be required for this lab?Lab apron, fire extinguisher, fume hoodSafety goggles, lab apron, fire blanketFire extinguisher, safety goggles, test tubeSafety goggles, lab apron, fume hood

If acid gets on your skin or clothes, wash at once with - Sulfuric acidSoap Water Oil

During a lab testing the properties of a mineral sample, John gets a small particle in his eye. Which piece of safety equipment would he use to remove the particle from his eye?A squeeze bottleA chemical showerAn eyewashForceps

When smelling a liquid -

Inhale deeplyUse the fume hood.Waft it toward youPour it on the table.

The ingredients above are used to make a bonding agent. The most important safety precaution when applying this bonding agent is - Dry it with a small flameWork in a well ventilated areaCover the work area with newspaperWear a lab coat

METERSTICKUsed to measure an objects length in centimeters or meters.

BEAKERUsed to hold and work with liquids. If graduated, it can serve to make approximate measurements of liquid volume in mL.

GRADUATED CYLINDERUsed to make accurate liquid volume measurements in mL. The volume is read from the lowest portion of the convex dip of the liquid as it sits in the graduated cylinder (meniscus). Graduated cylinders are available in a number of sizes.

EHRLEMEYER FLASKUsed to hold and store liquids. If graduated, it can serve to make approximate measurements of volume in mL. A main advantages of this type of flask is the fact that the mixing of its contents can be done with little or no spillage.

STOPWATCHUsed to measure time to the nearest 1/100th of a second.

THERMOMETERUsed for determining temperature. Most laboratory thermometers are calibrated in degrees Celsius and Fahrenheit.

TRIPLE BEAM BALANCEUsed to obtain an objects mass in g. [NOTE: If the measuring device uses springs against gravity, it is correctly referred to as a scale & measurements are described as weight not mass.]

SPRING SCALEUsed to measure weight of an object in grams or ounces.

pH TESTERSUsed to test the acidity [0 - 6] or alkanity [8 - 14] of a substance, a paper with pH indicator dye. The pH papers use a chemical that changes colors with a change of pH.

MICROPIPETTEUsed to extract or deliver extremely small amounts of a liquid in biology labs. The capacity of a micropipette can range from less than 1L to 1000l (1mL).

Which of the following will allow measurement of a liquids volume with the greatest precision?50mL cylinder graduated in 1mL increments100mL cylinder graduated in .5mL increments100mL cylinder graduated in 1mL increments200mL cylinder graduated in 5mL increments

The graduated clylinders below show the water level before and after a mineral sample was placed into the cylinder. What is the volume of the mineral sample?16mL32mL48mL80mL

Four groups measured the volume of acid required to neutralize a base. Which group made measurement with the most precision?

Which is the best estimate of the volume of solution released from the burette?47.3mL47.7mL48.3mL48.7mL

How much liquid was dispensed from the micropipette? .01mL .12mL .14mL .23mL

HANDLENSUsed to magnify objects up to 5X in order to make detailed observations.

PIPETTE/DROPPERUsed to extract or deliver small amounts of a liquid. Some are graduated to deliver exact quantities, but most allow for a "drop at a time" delivery.

TEST TUBEUsed to hold a small experiment, which would be used to conduct an investigation. Test tubes are made of specialized glass (can be heated and cooled without breaking). Test tubes must be handled carefully.

FORCEPUsed to pick up small items.

TONGSUsed to hold beakers or other hot lab equipment when transferring items from one location to another.

FUNNELUsed to transfer liquids from one container to another. It can also be used with filter paper to separate sediments from a liquid.

SCOOPULAUsed to transfer a small amount of solid of a powder from one location to another.

TEST TUBE CLAMPUsed to hold test tubes during an experiment.

TEST TUBE BRUSHUsed to clean test tubes and graduated cylinders.

TEST TUBE RACKDesigned to hold test tubes. However, it can be used to hold pipettes and stirring rods, etc. as well.

RING STANDUsed to support experimental equipment above the lab tables surface.

UTILITY CLAMPAttaches to the ring stand to hold other objects.

WIRE GAUZEProvides a barrier between the Bunsen burner and the object being heated.

BUNSEN BURNERUsed to heat substances. The burner can be regulated by changing the air and gas mixture.

HOT PLATEUsed as an alternative to the bunsen burner to heat objects.

LIGHT MICROSCOPEAllow a user to view small objects. Student microscopes can magnify between 40 X to 1000 X.

SLIDE/COVER SLIPSlide - a flat piece of glass used to serve as a platform for viewing objects under the microscope. Cover slip - used with a microscope slide to serves as a barrier between the object being observed and the microscope's objective lens.

PETRI DISHPrimarily used to grow bacteria. The petri dish can also be used to view seed germination, small animals, sedimentation, etc.

MORTAR & PESTLEUsed to grind solids into powders.

Which of these tools is most useful in measuring the wavelengths of visible light?Convex lensSpectroscopeMicroscopeConcave mirror
