Your guiding question: **How do we see and hear** **?** Area of interaction: **Human Ingenuity** (what you should know) || ==Resources== || ==Homework== || ==Deadline== || Ilmiö physics textbooks will be given out; bring them to each lesson. Translations are available from the link at the top of this section (login required). What is light ? Discussion. Light is a form of energy detected by our eyes. It gives things colour. Drawing light rays - they must be drawn with a ruler, arrows and must be continuous. Reflection from plane mirrors. || * recall that light is a form of energy 51-54 Chapter 6 || Qns p. 54 1,2,3,4,5 || For next lesson || Testing your understanding of ray diagrams and plane mirrors - where is the image ? 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 ? Discussion about rainbows and solar halos || * draw ray diagrams to show images in plane mirrors Chapter 8 || Read the Ilmiö chapter, p. 63-67 || For next lesson || 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. Real and virtual images. Uses of lenses || * draw ray diagrams to show refraction || Read Ilmiö chapter 10, p 73-77 || For next lesson || 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. Measuring the power of lenses. || * identify the main parts of the eye and know the function of each part Short animation showing light rays going into the eye How 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. || How do your reflectors (for use in winter) work ? They are not made with mirrors. Write a brief account - just a few lines. || For next lesson. || Total internal reflection - how reflectors work; demonstrations using prisms and optical fibres || * understand why light can be totally internally reflected Kidney stone removal using endoscope - short youtube clip Vocal cord polyp removal - clip Where does the light go when it enters a water drop ? - drawing a ray diagram || None set ||  || Colour - how white light is in fact made of many colours which can be split into a spectrum using a prism. This is called dispersion. Traditionally there are 7 colours of the rainbow in the English speaking world. We talk a bit about the history of this. 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. || * list the main colours of the spectrum of visible light Isaac Newton's experiment Primary and secondary colours of light
