Science As A Way Of Knowing: 5 Scientific Activities
Science as A Way Of Knowing Here are 5 scientific activities
Identify and classify each of the five scientific activities as empirical science, historical science, or non-scientific, using supported quotes. Determine which activity best demonstrates the power of the Scientific Method and which highlights its limitations, and provide rationales for your choices in a concise, 50-word summary.
Paper For Above instruction
Analyzing the classification of various scientific activities reveals the diverse approaches employed within scientific inquiry and underscores the strengths and limitations inherent in different methodologies. The activities span empirical investigations, which rely on direct observation and experimentation; historical sciences, which interpret data to understand past events; and some efforts that lack scientific rigor. This paper aims to categorize five specific scientific activities, evaluate their scientific nature, and identify the most illustrative examples of scientific power and limitations, supported by evidence from the activities themselves.
Classification of Activities
| Activity Number | Classification (E, H, NS) | Supporting Quote | Most Useful (MU) or Limitations (L) |
|---|---|---|---|
| 1 | E | "Measurements of gas volume reduction are taken every 5 minutes for 20 minutes." | |
| 2 | H | "Shells are seen to vary in shape from the bottom of the core column to the top." | |
| 3 | NS | "Drawings are evaluated by the instructor for accuracy." | |
| 4 | E | "DNA from mitochondria is degraded into small segments which are then amplified and sequenced." | |
| 5 | NS | "Quantitative values are taken from angiogram scans to compare before and after dietary regimes." |
Selection of Most Useful and Limitations of Scientific Method
Most Useful (MU): Activity 4 demonstrates the power of the scientific method through genetic sequencing, mutation rate analysis, and inference of human origins, exemplifying hypothesis testing and use of data to uncover historical and biological truths. Its systematic approach exemplifies scientific strength in human evolutionary studies.
Limitations (L): Activity 3, involving drawings of animals based on video observations, highlights limitations due to subjective interpretation and potential inaccuracies in visual representation, demonstrating how human bias and observational constraints can limit scientific precision.
Rationale for Choices
The activity with mitochondrial DNA sequencing (Activity 4) epitomizes the power of scientific inquiry because it involves rigorous data collection, laboratory experimentation, and analytical modeling, leading to profound conclusions about human evolution. Conversely, the activity involving artistic drawing of animals from video clips (Activity 3) demonstrates the limitations of science, where subjective interpretation and artistic skill impact accuracy, exemplifying the subjective constraints affecting some scientific efforts.
