LESSONS

Energy Transfer - Where does energy go? The aim of this section is to recognise that when energy is transferred from one form to another, something happens. It builds on students' Key Stage 3 knowledge of energy forms and applications.

• 1 GAINS AND LOSSES
• 3 GOLD FEVER
• 5 FREE FALL

Heat and Temperature - This section aims to make clear the difference between heat and temperature.

• 7 HOT AND COLD
• 9 IN HOT WATER
• 11 BOILED EGGS

Heat Transfer - This section consolidates students' knowledge of heat transfer by conduction, convection, radiation and evaporation, and extends their ideas of conduction into one practical application: house insulation.

• 13 BURNING QUESTIONS
• 15 HOT MOVES
• 17 KEEPING WARM

Forces and Effects - In this section, students become familiar with the names for different forces, consider adding forces and balanced and unbalanced forces. They are introduced to Newton's First and Second Laws.

• 19 NATURAL FORCES
• 21 NEWTON'S LAWS
• 23 MORE NEWTON

Pictures of Motion - Students begin by interpreting distance-time and speed-time graphs. This understanding is extended by two practical experiments with ticker timers and tapes.

• 29 THE BRISTOL FLYER
• 25 MOTION PICTURES
• 27 TICKER TIMING
• 29 THE BRISTOL FLYER

Kinetic Theory - The aim of this section is to introduce the main points of the Kinetic Theory to students and to conduct prac-tical experiments to reinforce their understanding.

• 31 KINETIC QUESTIONS
• 33 SMOKE CELLS
• 35 PURPLE HAZE

Mass and Weight - Through a careful examination of the concepts of weight and mass, and practical investigation of these concepts in action, students come to understand why weight and mass is measured in different units.

• 37 NEWTONS AND KILOS
• 39 FEELING THE WEIGHT
• 41 OTHER PLANETS

Electric Currents - This section aims to clarify the concepts of electric current, potential difference (voltage), electric charge and energy. Students plan electrical circuits on paper, conduct a practical, using appropriate components and circuitry, and make detailed records of their results.

• 43 CUT AND PASTE
• 45 CHARGE AND TRANSFER
• 47 ELECTRIC MATHS

Waves - What is a wave, and what determines its size and speed? This section employs a series of simple practical experiments to investigate the physics of water waves.

• 49 MAKING WAVES
• 51 SURF'S UP!
• 53 SHALLOW END

Magnetic Forces - This section begins by studying the forces that exist between magnets, links this to the idea that motor force is an interaction between two magnets, and concludes with an extended practical in which students build a simple 'Nuffield' electric motor.

• 55 POLES APART
• 57 MOTOR EFFECT
• 59 MAKE A MOTOR
