Unit 1 - Sports and forces

Content

The concept of force as a push or pull
To represent forces in sketches that show magnitude and direction of force
The types of force: gravity/weight, friction, air resistance, friction in water, buoyant force, normal force, forces in sports
The effect of force on motion through understanding of balanced forces (no change to motion); unbalanced forces (acceleration, deceleration)
Acceleration and deceleration (speeding up, slowing down, going at a steady or constant speed)
The effect of increase or decrease of net force on motion of objects
The forces in sports and contribution of science to improvement of safety and performance.

Unit 2 - Nutrition

Content

The energy flow through biomass.
To appreciate the energy content of different carbohydrates and lipids.
That all energy comes from the sun.
That photosynthesis is the process whereby plants store energy as carbohydrates.
The Celsius temperature scale.
The concept of a balanced diet.
That excess nutrients can be as damaging as deficiency.

Skills and understanding

Content

The kinetic theory of particles and motion
States of matter and changes of state
The aggregation of particles into matter
Particles as atoms and molecules
Aggregation of matter as elements and compounds
The periodic table as a data table of the elements (atoms)
Pure substances and mixtures
Solutions and dissolution
Crystallisation and precipitation
Separation of mixtures, filtration, decanting, evaporation, distillation, magnetic separation, floatation
Chemical techniques to obtain new materials (electrolysis)

Skills and understanding

Work safely in science laboratories
Recognise mixtures and pure substances
Use solutions as a type of mixture
Use the concept of solution concentration (dilute, concentrated, saturated) appropriately.
Physically separate mixtures using a variety of techniques (filtering, dissolving, evaporation, condensation, distillation)
Recognise elements and compounds
Identify common element symbols and locate them in the periodic table

Content

Skills and understanding

Content

Form and function of senses of sight and hearing.
Waves as energy form and varieties of waves (sound as mechanical waves) and light (electromagnetic waves).
The properties of waves, amplitude and frequency.
The ranges of wavelengths/frequencies that are perceptible by humans and animals and safety limits.
Impact of modern technology on issues of hearing and sight (cochlear implants for severe hearing problems).

Skills and understanding

Use the term frequency correctly
Use the term amplitude as the "size of the wave" measured from the undisturbed point.
Describe the characteristics of waves that can be transmitted, absorbed or reflected by materials or when entering different mediums. They can also be refracted when being transmitted which means there path is changed.
Describe the operating principles of the ear drum.
Describe the operating principles of the eye
Describe waves as caused by vibrations and transfer energy
Describe the difference between longitudinal waves and transverse waves
