Study Notes
Classification
- Living things are classified based on similarities and differences in structural features
- Classification helps to organise the diversity of living things
- Simple keys can be used to identify plants and animals
- Micro-organisms can be classified into groups
Cells
- Living things are made of cells
- Cells have specialised structures and functions
Electrostatic Charge
- Objects can acquire an electrostatic charge
- Charged objects interact with each other
- Everyday situations where electrostatic forces can be observed, for example, lightning strikes and dust storms
Gravity
- Gravity pulls objects towards the Earth’s centre
- Gravity is an unbalanced force in many everyday situations
- Mass and weight are distinct concepts
Magnets and Electromagnets
- Magnetic poles interact when brought close together
- Magnets and electromagnets are used in everyday devices and technologies
Earth's Structure
- The Earth's structure comprises core, mantle, crust and lithosphere
Landforms
- Landforms are created through physical and chemical weathering, erosion and deposition
Rocks
- Sedimentary, igneous and metamorphic rocks are formed by processes within the Earth over a variety of timescales
- These rocks contain minerals
