clean the eyes by using the eye wash fountain for 15 – 30 minutes to flush the
eyes. Remove contact lenses before using eye wash.
b. Fire blanket is used to extinguish the fire.
c. Shower is used when a fire or a chemical spill happens. Water is poured over
the body for 15 – 30 minutes flushing down the chemical off the body.
d. Chemical spill kit is used to clean chemically contaminated materials in case of
chemical spills in the lab. The opposite of the chemical is used to neutralize the
spill. For acid or base spill, an opposite of base or acid is used. Use soap and
water to clean body immediately.

, Broken glass container is used when broken glass materials need to be disposed
off. The waste might involve broken class utensils, decoration pieces, windows etc.
The disposal container ensures that person handling the disposal doesn’t get hurt.
Biological hazardous materials container is used to dispose off disease causing
organisms like bacteria and virus that can transfer or transmit to other people
coming in contact like those handling the trash. An example is the disposal of
medicinal waster of elderly at home like syringes, needles or other used materials
like cloth that might contain blood especially from a hepatitis B patient.

a. An adult bottlenose dolphin is 118 inches in length. Given that one
inch = 2.54 cm, convert this length to centimeters.
one inch = 2.54 cm
118 inches X 2.54 cm = 299.72 cm

g while the average mass (weight) of a sea otter in the experimental
group was 40.82 kg. What is the average difference in weight between
the two groups in grams?

a. Normal body temperature of a walrus is 97.90 F. Convert this to
Celsius.
oC = (oF – 32) x 5/9
(97.90 F – 32) x 5/9 = 36.6 oC

5. What is the purpose of the control group in the Scientific Method? Explain
in detail and be sure to use examples. (2 points)
The purpose of the control group in the experiment is to have constant samples
that can be compared to the experimental group samples so the results can be
deduced from the experiment. The variable in the control group is kept constant
and the changes in the same variable in the experimental group determines and
tests the hypothesis of the experiment.
