observe
Definition
In science, observation is the act of gathering information about the natural world through the senses. Observations can be made using the naked eye, with tools like microscopes and telescopes, or with other instruments.
Observations are important in science because they provide the foundation for scientific knowledge. Scientists use observations to make inferences and conclusions about the natural world. They also use observations to test hypotheses and theories.
There are many different types of observations that can be made in science. Some common types of observations include:
- Qualitative observations: These observations describe what something looks like, smells like, tastes like, or feels like.
- Quantitative observations: These observations measure something, such as the length, weight, or temperature of an object.
- Temporal observations: These observations measure how something changes over time.
- Spatial observations: These observations measure the location of something.
How can the word be used?
In social situations, observe is often used to describe the process of paying attention to the behaviour of others.
Different forms of the word
Verb: To watch or pay attention to something carefully.
Noun: The act of observing something.
Etymology
The word "observe" comes from the Latin word "observare," which means "to watch over" or "to guard." The Latin word "observare" is also the source of the French word "observer" and the Spanish word "observar.".
The word "observe" was first used in English in the 14th century. It was used to refer to the act of watching or paying attention to something carefully.

AQA Science Exam Question and Answer
Question:
Explain the importance of observation in the scientific method. Provide examples of how observation contributes to our understanding of the natural world.
Answer:
Observation is a fundamental aspect of the scientific method, serving as the starting point for inquiry and investigation. It involves gathering information through our senses or using tools to collect data about the natural world. Observations provide the raw data that scientists use to formulate hypotheses, make predictions, and draw conclusions.
Observations are crucial because they provide empirical evidence that can be used to test hypotheses and theories. For example, in the field of biology, observing the behaviour of animals in their natural habitat can offer insights into their social interactions, feeding habits, and mating behaviours. Similarly, in chemistry, observing the colour change of a chemical reaction can indicate the occurrence of a chemical change.
Moreover, observations can lead to the discovery of new phenomena or relationships. One notable example is Sir Isaac Newton's observation of an apple falling from a tree, which led to his formulation of the theory of gravity. In astronomy, observations of the motion of planets and stars over time helped astronomers like Johannes Kepler develop the laws of planetary motion.
