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
