I) Which of the following are recognized limitations of science? (1 point)

Question

Science is unable to study phenomena that cannot be observed or measured.
Science provides absolute and unchanging truths.
Science can address questions of morality and ethics.
Science can explain every aspect of the human experience.
J) Which of the following is a crucial lab safety practice? (1 point)
Ignoring safety data sheets since they are not important.
Wearing appropriate personal protective equipment (PPE) at all times.
Eating and drinking in the laboratory to maintain energy levels.
Disposing of chemical in any sink to ensure quick cleanup.
K) Which of the following is an important safety procedure for scientists working in a natural
environment? (1 point)
Inform someone of your location and expected return time, and carry appropriate safety and
emergency equipment.
Always work alone to minimize disruptions.
Ignore weather conditions as they have no impact on fieldwork.
Leave all gear behind to travel light.
L) Which of the following hypotheses is the best for this scenario?
"In a high school science lab, a group of students is conducting an experiment to determine the
amount of water needed to grow a seed into a fully mature plant. The students are
investigating the effect of varying water amounts on the growth and development of bean
plants." (1 point)
The amount of water has no effect on the growth and development of bean plants; all plants will
grow equally well regardless of the water amount.
Bean plants will grow best when they receive the most amount of water, as this will provide them
with more nutrients and encourage faster growth.
Bean plants will grow best when receiving a moderate amount of water, and excessive or
insufficient water will result in stunted growth or plant mortality.
Bean plants will grow best when they receive the least amount of water, as this will encourage
them to develop deeper roots and seek out water.

Answer 1

I) The recognized limitations of science include:

• Science is unable to study phenomena that cannot be observed or measured.
  This statement is true, as science relies on empirical evidence and measurable phenomena.

J) A crucial lab safety practice is:

• Wearing appropriate personal protective equipment (PPE) at all times.
  This is essential for ensuring the safety of individuals working in a laboratory environment.

K) An important safety procedure for scientists working in a natural environment is:

• Inform someone of your location and expected return time, and carry appropriate safety and emergency equipment.
  This practice is crucial for safety in potentially hazardous situations.

L) The best hypothesis for the scenario described is:

• Bean plants will grow best when receiving a moderate amount of water, and excessive or insufficient water will result in stunted growth or plant mortality.
  This hypothesis reflects an understanding of the balance needed for optimal plant growth.
