Scientific Method
The first step in the scientific method where one may notice something.
What are observations?
A glass container with measurement markers and a consistent wide cylindrical shape throughout.
What is a glass beaker?
True or false: It is not acceptable to consume any materials or chemicals in a laboratory?
True
The list of things and equipment needed to perform a specific experiment that is written out in a professional and legal lab report.
What are materials?
The measurement system used by the majority of the world with the exception of the United States and some other smaller nations.
What is the metric system?
A question proposed typically and officially stated in an ‘if... then’ statement.
What is a hypothesis?
A tool that uses suction to transport small amounts of a liquid and only drops an extremely controlled amount of it into another container. It is pinched to release the liquid and is un-pinched to take in a liquid.
What is a pipet?
True or false: During a lab experiment, open toed shoes and short sleeved shirts are acceptable?
False
The step-by-step instruction provided in a lab report so that the experiment may be easily repeatable.
What is the procedure?
My plants were potted at the same time with the same amount of soil in each pot and are watered as evenly as possible. Sprouts of the same type came up in a synchronized manner. What conclusion could be drawn?
The time at which a plant begins to sprout may be genetically encoded. (Other conclusions will be accepted as well.)
After an experiment this is drawn to sum up or conclude the results of the experiment.
What is a conclusion?
An electrically induced heat source to maintain a stable temperature for a mixture for long periods of time. The mixture will rest on a flat bed and will be heated from below.
What is a hotplate?
If dangerous or possibly corrosive materials are present in one’s eye, they should head here immediately!
What is the eyewash station?
The group that does not receive the independent variable through trials. It acts as the usual and comparable data point.
What is the control group?
The amount of matter in an object. This remains constant despite gravitational flux and is thus different from weight, which does fluctuate with gravitational pull.
What is mass?
A proven fact of nature or law to which anything will almost always abide. This can be drawn from many repeated experiments.
What is a scientific theory?
A scientific tool used to heat and combust chemicals in a controlled manner. This is a tall rod with a gas flame.
What is a Bunsen Burner?
Unacceptable behavior in a lab where one may fool around.
What is horse play?
The factor that is determined by the independent variable in an experiment. This is directly influenced by the changes in initial conditions.
What is the dependent variable?
The amount of matter in an object per unit cubed of volume.
How to calculate:
If a solid is X grams, and the volume is Y centimeters cubed, then this is calculated with X (Grams) / (Divided by) Y^3 (Number of cubic centimeters) to get X grams per cubic centimeter.
What is density?
After determining something with experimentation, one is to...
Publish findings and share results.
An extremely accurate tool to measure the volume of a liquid precisely and can also measure fluid displacement.
What is a graduated cylinder?
True or false: As it is a laboratory, it is reasonable to mix random chemicals for a reaction?
False, do not combine chemicals without supervision or instruction!
A constructed graph or chart from the data drawn that is used to determine causations, and correlations is in this section of the lab report.
What is the analysis?
The temperature measurement that relies on the same rate of thermal flux as Celsius but zero represents absolute zero rather than water's freezing point.
What is Kelvin?
