Obtaining in Science
Obtaining in science refers to the process of acquiring data, materials, or information through various methods and techniques. It is a crucial step in the scientific method and is essential for conducting experiments, making observations, and gathering evidence to support scientific claims and theories.
Methods of Obtaining
There are several methods of obtaining information and materials in science:
- Experimentation: Conducting controlled experiments to gather data and test hypotheses.
- Observation: Making careful and systematic observations of natural phenomena.
- Research: Utilizing existing literature, scientific papers, and other sources to gather information.
- Data Collection: Using various tools and instruments to collect quantitative and qualitative data.
- Sampling: Collecting representative samples from larger populations for analysis.
Study Guide Questions
- What is the importance of obtaining in the scientific method?

Key Concepts to Remember
When studying the topic of obtaining in science, remember these key concepts:
- The process of obtaining involves collecting data, materials, and information through various methods such as experimentation, observation, and research.
- Obtaining is essential for supporting scientific claims and theories, and it is a fundamental step in the scientific method.
- Data collection methods can be qualitative (descriptive) or quantitative (numerical), and both are important for scientific investigations.
- Sampling techniques are used to collect representative samples from larger populations, ensuring the reliability of the obtained data.
- Obtaining plays a critical role in forming and testing scientific hypotheses, ultimately contributing to the advancement of scientific knowledge.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
