Lenses
Photography has never been as popular as it is in this age. With social networking sites and cheaper digital cameras or smartphones (although SLR cameras are still quite expensive!), almost anybody could take a shot at photography. Learn about the science behind the technology of being able to capture beauty and emotion. Learn about lenses.

The Electromagnetic SpectrumHere are the details of what your report should contain. Please be prepared and take note that this is counted as a Unit Test as well.
|
RefractionIt happens everyday but has never become scientifically cool until now. Learn about the concept of refraction, apparent depth, dispersion and total internal reflection.
|
Reflection of Light
What is reflection? How do we see an image on a plane mirror? Learn how to construct ray diagrams for plane mirrors and discover the many uses of reflection. Understand what total internal reflection is and where this concept is widely used in this age.
|
Sound
Know the different properties of sound like frequency as to pitch and amplitude as to loudness. Recall the method of determining the speed of sound through its echo and understand why it slows down as it moves from vacuum to gases to liquids to solids.
|
Mechanical Waves
Discover the nature of mechanical waves. There are transverse waves like plucked guitar strings and then there are longitudinal waves like sound. Know about wave speed, amplitude, period, frequency and wavelength.

Heat and Heat Transfer
Definition of heat; three modes of heat transfer and their mechanisms; examples of each mode of heat transfer; applications of heat transfer.
|
Thermal ExpansionDefine expansion and give examples of experiments showing expansion; uses and applications of expansion.
|
States of MatterSolids. liquids and gases and their respective characteristics; pressure and how it relates to volume and temperature; kinetic energy of molecules and temperature.
|
Power and Efficiency
You have given a class report on the different sources of energy. Trace the processes involved again by looking at the different energy transformations involved. Which of these energy sources is most efficient? Then recall the definitions and formulas for power and efficiency.
|
|
Work and Energy
Work and energy are the same thing. The physics definition of work is different from our common understanding of what work is. Learn more about energy and it various forms and how it can be transformed from one to the other.
|
Forces
What forces are acting on you right now? Discover the different forces around you and their effects.
|
Special Project: Sources of Energy
The information you need to complete your report are contained in the file below.
The tentative first day of reporting is on October 24, Wednesday, for IGCSE 1B and October 23, Tuesday for IGCSE 1A, so be prepared. Remember, this counts as one of your unit tests!
|
Describing Motion
We describe motion by the speed and acceleration of the moving object. Learn about what each quantity means and the formulas involved. Discover the story behind motion graphs and what information we can get out of the gradients of each type of graph as well as the area under a speed-time graph.
|
Density
We have done two experiments on determining the density of steel. Relive those moments and recall the definition and equation for density, the formulas for volume of regularly-shaped objects and the different applications of knowing and using density. Remember, we even had Jack Sparrow on our discussion and how ridiculous it was for pirates like him to drag or carry a chestful of gold.
|
Measurement
We have learned about different physical quantities that are used in physics and how important it is to measure them accurately. We have also learned about base quantities and corresponding units.
