Lab Safety

Toxic: Corrosive: Dilute: Flammable: Waft: Biohazard:

Poisonous, harmful

Acid, burns the skin

lower the concentration, (acidwater)

catches on fire easily

safely smell, protect your respiratory system

caution bodily fluids (blood, urine, bacteria, fungi)

•Observe lab symbols

Electrical Hazard Corrosive Open Flame

Prohibited

Fire Extinguisher

Toxic Chemical Flammable

LAB EQUIPMENT

Measurements Temperature: Mass: Volume: Time: Distance: Accurate: Precise:

thermometer(*C, *F, Kelvin)

triple beam balance, scale, (kilograms or grams)

Graduated Cylinder, buret, pipet (milliliters)

stopwatch (hours, minutes , seconds)

Meter stick ( kilometers, meters, centimeters)

Exact true value (accuRIGHT)

consistent, close together, nearest decimal (pREPEATABLE)

Equipment Used for:Beaker

Flask Test tubeGraduated cylinder

BuretPipet

TongsFume hoodStopwatch or Timer

Triple beam balance or scale

ThermometerMeter stick

Never to measure, only to hold and heat liquids

Used to swirl and slows evaporation rate

Used to observe chemicals

Used to measure volume in mL (precise)

Used to measure volume in mL (more precise)

Used to measure small amounts of volume in mL (most precise)

Used to hold HOT beakers

Used when working with toxic gases or noxious fumes

Used to measure time in hours, minutes, seconds

Used to measure mass in kilograms, grams, and milligrams

Used to measure temperature in *C, *F, and Kelvin

Used to measure distance in kilometers, meters and centimeters

Scientific Method

Problem: Observation : Inference: Hypothesis:

Independent variable

Dependent variable:

Control group: Experimental group: Constant:

question you want to solvesee, smell, taste, hear, feel

gathered from cluestry to answer or solve the question (If _______, then ________)

: added, tested or changed in an experiment (x-axis)

what happened from the change, has to measurable, (y-axis)

group or set up that was left alone

groups tested (with independent variable)what was the same in all groups

TIM & MOBY’s “Scientific Method” Problem: Why is Moby’s plant dying even though it is being

watered every day? Observations:The leaves are brown and falling off, and the soil is

wet and squishy Inference: Maybe Moby is watering his plant too much.

Hypothesis: Fig trees grow best when watered only once a week.

Independent variable: Amount of water Dependent variable: The plants growth

Control group: A Experimental groups: B,C,D

Constants: same kind of plant, same pot, same soil, and same amount of sunlight

Conclusion: Fig trees grow best when watered only once a week
