Study Notes
Scientific Models
- A scientific model is a representation of an object, system, or concept.
- Physical models are tangible representations like a globe.
- Scientists use models to help them understand complex systems.
Scientific Mindset
- A critical mindset is essential for scientists to explore new ideas and challenge existing theories.
- Persistence is the ability to keep working despite obstacles.
- Humility involves recognizing the contributions and ideas of others.
- Open-mindedness is the willingness to change views when presented with new evidence.
Example of Physical Models
- The structure of DNA is a physical model representing a complex biological system.
Physical Changes
- Melting ice is an example of a physical change.
- Sublimation is the process of a solid changing directly into a gas.
- Freezing is the process of a liquid changing into a solid.
Scientific Method Steps
- Identify variables: define the factors that are being investigated in an experiment.
- Independent variable: the factor that is changed or manipulated by the experimenter.
- Dependent variable: the factor that is measured or observed in response to changes in the independent variable.
- Controlled variable: the factor that is kept constant throughout the experiment to ensure a fair test.
Characteristics of a liquid
- Liquids have a fixed volume but take the shape of their container.
- Liquids can flow.
