Principles Governing Science's Characteristics
Learning about science isn't just about doing experiments. It's like thinking you'll understand photosynthesis by watching a leaf in the sun – that doesn't work for science either. We need to teach students about the actual nature of science, not just the science content or exciting investigations. Here are some key tenets that primary to secondary school students should learn to help them get a clearer, more accurate understanding of the scientific enterprise.
The Tentative Nature of Scientific Knowledge
Scientific knowledge might seem reliable and robust, but it's not set in stone and perfect. It's subject to change due to new evidence or a fresh interpretation of existing evidence. This means we can't actually claim 'absolute truth' in science, and laws and theories may change over time.
The Empirical Nature of Science
Science is based on observations of the world around us. Scientists make interpretations and build scientific knowledge from what they see. New evidence can bring revisions to existing scientific knowledge.
The Inferential, Imaginative and Creative Nature of Science
Science isn't just about gathering observable evidence and organizing it. Scientists need to interpret observations, make inferences and use their imagination in every aspect of their work, whether it's making sense of observations, coming up with new ideas or designing investigations.
The Subjective and Theory-Laden Nature of Science
Different scientists can interpret the same data differently because their minds aren't blank slates. Their prior knowledge, theoretical beliefs, experiences, culture, training, expectations, and biases all play a role in their observations and conclusions.
The Socially and Culturally Embedded Nature of Science
Science is produced within a society and culture, so social and cultural elements like politics, economics, power structures, religion, and philosophy impact the science knowledge produced and how it is accepted. This means that the direction and products of science will be influenced by the society and culture in which it is conducted.
These key tenets can't be taught as a list to be memorized. Instead, they should be understood within the context of any science topic or investigation and incorporated into all science teaching. They can be reframed as questions to promote effective teaching of the nature of science and a deeper understanding of NoS ideas.
Here are some activities that can help students develop their understanding of the nature of science:
- The Extra Piece: A problem-solving game that requires students to make connections and work together.
- Mystery Boxes: A hands-on, open-ended activity where students use their observations, inference, and imagination to solve a mystery.
- Scrambled Sentence: A fun way to have students practice critical thinking and sentence structure by rearranging scrambled sentences to make sense.

You'll find an interactive flowchart that represents the process of scientific inquiry, as well as other resources to help you teach the nature of science effectively.
Science education and self-development should involve teaching students the tentative nature of scientific knowledge, acknowledging that scientific knowledge is not set in stone and is subject to change. This understanding can help students appreciate the dynamic and ever-evolving nature of scientific understanding.
Furthermore, it's essential to emphasize the empirical nature of science, indicating that science is based on observations and interpretations of the world around us, with new evidence constantly shaping and revising scientific knowledge. This approach encourages a deep and critical examination of the world, which is crucial for personal growth and development.
