Questions and Answers|2026 Update |
100% Correct.
How do you measure an object using a ruler in cm, mm, and inches? - CORRECT
ANSWER-take the number of centimeters and multiply by 10 to get millimeters. mm to
cm divide by 10. cm to inches multiply the centimeters by 2.54 to get the length in
inches.
What volume measurement does a graduated cylinder use? - CORRECT ANSWER-
The graduated cylinder measures volume of a liquid. Volume is measured in LITERS. a
graduated cylinder uses milliliters.
What is the curve formed by water sticking to glass called? Be able to accurately read
the volume of a liquid. - CORRECT ANSWER-meniscus. To get the most accurate
reading of the volume of a liquid, read the meniscus at its lowest point.
What unit of measure is used to determine the volume of a solid? - CORRECT
ANSWER-cubic units
What is water displacement? Be able to accurately determine the volume of and object
using this method. - CORRECT ANSWER-When an object enters water, it pushes out
water to make room for itself. The object pushes out a volume of water that is equal to
its own volume. This is called displacement. Measure the beginning, measure the end,
and subtract the two numbers.
Be able to covert units of measure- dimensional analysis. (You need to remember
conversion factors) - CORRECT ANSWER-
What are the lab safety rules? - CORRECT ANSWER-look at document on canvas
What is the metric unit of measure for length/distance? - CORRECT ANSWER-meter
(m)
What is the metric unit of measure for volume/capacity? - CORRECT ANSWER-liter ( L)
What is the metric unit of measure for mass/weight? - CORRECT ANSWER-gram (g)
What is the metric unit of measure for temperature & time? - CORRECT ANSWER-
Celsius / the second
, What is an independent variable? - CORRECT ANSWER-Independent variable is also
known as the experimental variable. The independent variable is the factor that is being
tested.
What is a dependent variable? - CORRECT ANSWER-The dependent variable of the
experiment is the data, which is the result of the experiment. The dependent variable is
a result of the manipulation of the independent variable.
What is a control group? - CORRECT ANSWER-A control group goes through all
aspects of the experiment but is not exposed to the independent variable.
A botanist wants to see how different colored light waves influence the growth of pea
plants. She puts the same number of seeds into three identical pots with the same kind
and amount of soil. She then gives them the same amount of water every three days for
the length of the experiment. One pot is placed into a dark windowless closet. Another
pot is left on the windowsill, and the third is placed under a lamp with a green bulb. She
records the height of each plant every day for three months. Identify the independent
variable and the dependent variable - CORRECT ANSWER-the independent variable is
the color of the light given to the plants, the dependent variable is the height of each
plant
What is an organic compound? Give and example. - CORRECT ANSWER-By definition,
organic molecules contain C (carbon) atoms arranges in chains or rings with at least 1
H (hydrogen) atom present. Examples of organic molecules are carbs, lipids, proteins,
and nucleic acids. Ethane is a example of a carbon molecule because it is made up of 2
carbon atoms that bond with 6 hydrogen atoms. Organic compounds are cells that are
mostly made up of CHONP.
What is an inorganic compound? Give an example. - CORRECT ANSWER-Inorganic
compounds are compounds that do not contain carbon in the form of chains or rings. An
example is phosphoric acid.
What reagent is used to test for reducing sugars? - CORRECT ANSWER-Benedict's
solution. Benedicts reagent undergoes a complex color change when it is reduced. The
intensity of the color change is proportional to the concentration of reducing sugar
present. The color change sequence is blue, green, yellow, orange, brick red.
What reagent is used to test for starch? - CORRECT ANSWER-Iodine solution. When a
starch is present the color changes from blue to black.
What reagent is used to test for lipids? - CORRECT ANSWER-Sudan IV. If lipids are
present the Sudan IV will stain them reddish-orange.
