This page contains all the resources used in lessons for Topic 1 as well any others I feel you may find useful. Alongside each topic is also a description of what you are expected to know, this has been taken directly from the specification.
Models of the Solar System
Describe how ideas about the structure of the Solar System have changed over time, including the change from the geocentric to the heliocentric models and the discovery of new planets.
Demonstrate an understanding of how scientists use waves to find out information about our Universe, including:
a the Solar System
b the Milky Way
Discuss how Galileo’s observations of Jupiter, using the
telescope, provided evidence for the heliocentric model of the Solar System.
Compare methods of observing the Universe using visible light,including the naked eye, photography and telescopes.
Reflection and Refraction
Recall that waves are reflected and refracted at boundaries between different materials.
Explain how waves will be refracted at a boundary in
terms of the change of speed and direction.
Lenses and Telescopes
Explain how to measure the focal length of a converging lens using a distant object.
Investigate the behaviour of converging lenses, including real and virtual images.
Investigate the use of converging lenses to:
a measure the focal length using a distant object
b investigate factors which affect the magnification of a
converging lens (formulae are not needed).
Explaim how the eyepiece of a simple telescope magnifies the image of a distant object produced by the objective lens (ray diagrams are not necessary).
Describe how a reflecting telescope works.
Describe that waves transfer energy and information without transferring matter.
Use the terms of frequency, wavelength, amplitude and speed to describe waves.
Differentiate between longitudinal and transverse waves by referring to sound, electromagnetic and seismic waves.
Use the correct equations to calculate wave speed, distance, frequency and time.
