Practical Investigation

• Investigate the power consumption of low-voltage electrical items.
• Investigate factors affecting the generation of electric current by induction.
• Investigate how the nature of a surface affects the amount of energy radiated

or absorbed.

• Investigate models to show refraction, such as toy cars travelling into a region of sand.
• Investigate the areas beyond the visible spectrum, such as those found by Herschel and

Ritter, who discovered infrared and ultraviolet (UV) respectively.

• Investigate the relationship between potential difference (voltage), current

and resistance.

• Investigate the relationship between force, mass and acceleration.
• Investigate the forces required to slide blocks along different surfaces, with differing

amounts of friction.

• Investigate how crumple zones can be used to reduce the forces in collisions.
• Investigate forces between charges.
• Conduct experiments to show the relationship between potential difference (voltage),

current and resistance, for a component whose resistance varies with a given factor, such

as temperature, light intensity and pressure.

• Investigate the motion of falling.
• Investigate momentum during collisions.
• Investigate power by running up the stairs or lifting objects of different weights.
• Investigate the critical angle for Perspex®/air, glass/air or water/air boundaries.
• Investigate factors affecting the height of rebound of bouncing balls.
• Investigate the temperature and volume relationship for a gas.
• Investigate the volume and pressure relationship for a gas.
• Investigate the absorption of light by translucent materials in order to simulate the

absorption of rays.
