Question

1. check the box if the statement describes descriptive, experimental, or applied research.

a scientist studies different metals to see which is best for making prosthetic limbs (i.e., artificial arms or legs).
done to test hypotheses
a scientist wants to know how the state of matter (solid, liquid, or gas) is affected by temperature.
studies a phenomenon through observations
has an independent and dependent variable
is used for real - life scenarios

Explanation:

• Applied research: Focuses on solving real - world problems. The study of metals for prosthetic limbs and research used for real - life scenarios fall into this category as they aim to apply knowledge to practical, real - world situations (making prosthetics and real - life use respectively).
• Experimental research: Involves testing hypotheses and having independent and dependent variables. When a scientist wants to know how the state of matter is affected by temperature (temperature is the independent variable, state of matter is the dependent variable) and when research is done to test hypotheses, it is experimental.
• Descriptive research: Studies a phenomenon through observations.

Answer:

• A scientist studies different metals to see which is best for making prosthetic limbs (i.e., artificial arms or legs): applied
• done to test hypotheses: experimental
• A scientist wants to know how the state of matter (solid, liquid, or gas) is affected by temperature: experimental
• studies a phenomenon through observations: descriptive
• has an independent and dependent variable: experimental
• is used for real - life scenarios: applied
