What is light ?

Shadows in space - moon phases and eclipses || understand light is a form of energy that helps us see; we cannot light itself. Luminous and incandescent objects give out their own light. Most objects reflect light. Phases of the Moon. Eclipses || Ilmiö p.48

Eclipses - why don't they happen every month ?

Comet Lovejoy || Pay attention to the colours you see in nature, particularly the sky. We may have northern lights,solar halos and there is a comet in the sky if you look hard enough. No written work - just look at the world! || None || 14/1/15 || Reflection of light || How to draw light rays correctly - three rules (straight lines; arrows; continuous) Finding the image- Pepper's ghost illusion Is the image real or virtual ? Law of reflection - measuring the angles of incidence and angles of reflection || Pepper's Ghost

Pepper's Ghost Illusion

Ilmiö p.51-53 || Learning the vocabulary and rules for drawing light ray, so that you can label a diagram correctly. Finnish version p.53 Ilmiö || Next week || 21/1/15 || Testing your understanding of ray diagrams.
 * 4

Two way mirrors.

Importance of sunglasses in winter.

Periscopes.

Use concave and convex mirrors - how are the rays reflected? What sort of images are found? What are the uses of convex and concave mirrors ? || * Use light ray diagrams to explain how a periscope works
 * investigate rays reflected from concave and convex mirrors
 * describe images as real or virtual
 * describe images as enlarged (magnified) or diminished
 * describe images as inverted or the right way up || Cycling light video

Making a periscope

Lateral inversion video

How a kaleidoscope works

Satellite dish cooker

Ilmiö p 63-68 Chapter 8 || None set ||  || 28/1/15 || Refraction of light - how the change of direction of light affects things like the depth of objects under water. Drawing ray diagrams to show refraction through rectangular blocks and lenses. Convex and concave lenses and their images || * draw ray diagrams to show refraction
 * 5
 * know that refraction is caused by the change of medium through which light passes
 * identfiy when a light ray bends towards or away from the normal
 * investigate rays refracted by concave and convex lenses || Ilmiö chapters - see homework >>>

A litre of light project

Original video || Read from Ilmiö: Chapter 7 Valon taittuminen p.55-58 up to 'Kokonaisheijastus' (Total Internal Reflection), and Chapter 9 Erilaisia Linssejä - the whole chapter. Just read this through and you will be able to ask questions next week if you do not understand it. || For next lesson || 2/2/15 || The structure of the eye: you can see the dissection of an elk eye. Identifying the parts and the job they do in the eye. Common eyesight problems - near sight (likinäköinen) and far sight (pitkänäköinen). Correcting these problems with lenses.
 * 6

Colour - how white light is in fact made of many colours which can be split into a spectrum using a prism. Traditionally there are 7 colours of the rainbow in the English speaking world. We talk a bit about the history of this. || * identify the main parts of the eye and know the function of each part
 * draw ray diagrams to show how a real image is formed in the ye
 * explain how common sight problems can be corrected using lenses
 * list the main colours of the spectrum of visible light || Short animation showing light rays going into the eye

ow the eye works - brief youtube video Ishira Colour Vision test Note: if you are not going to watch the dissection, go to this page. It may be a bit childish but it has some great information and takes you through the parts of the eye very well. When you have read this carefully you can have a go at this quiz.

|| Look at the traffic light sequence to check that it does in fact help colour blind people ||  || 9/2/15 || Total internal reflection - how reflectors work; demonstrations using prisms and optical fibres
 * 7

Colour can be identified by wavelength and frequency.

Objects appear coloured because of the colour of light they reflect.

Primary and secondary colours of light (these are different to the primary and secondary colours of dyes or pigments in art)

You will also watch a film that shows coloured objects in different lights and also tries to explain why the sky is blue.

Introducing basic ideas about waves: frequency, wavelength, speed

Waves in nature - sound, light, water. || * understand why light can be totally internally reflected
 * give examples where this phenomenon is used
 * draw correct ray diagrams to show total internal reflectio
 * know that colours of light are identified by values of frequency and wavelength
 * complete a diagram to show how the primary colours of light make the secondary colours
 * explain why a red object is red when seen in red light but black in green light || Ilmiö p 58-59

Sound as a vibration of particles Frequency and loudness Ultrasound How we detect sound - the structure of the ear || * describe how sounds form and move
 * identify parts of the ear and their function
 * explain common hearing problems || How the ear works
