A.1.1.5 Charged coupled device
Use of CCD to capture images. Structure and operation of the charge coupled device: A CCD is silicon chip divided into picture elements (pixels). Incident photons cause electrons to be released. The number of electrons liberated is proportional to the intensity of the light. These electrons are trapped in "potential wells" in the CCD. An electron pattern is built up which is identical to the image formed on the CCD. When exposure is complete, the charge is processed to give an image. Quantum efficiency of pixel > 70%.
A.1.2 Non-optical Telescopes
Single dish radio telescopes, I-R, U-V and X-ray telescopes. Similarities and differences compared to optical telescopes including structure, positioning and use, including comparisons of resolving and collecting powers.

Concepts: Refracting Telescopes, Reflecting Telescopes
Part of a Blended Classroom taught at Millard West High School.
Produced for Millard Public Schools by Justin Higgins.
Lesson Plans and how the course is structured:
Learn about the effect of our atmosphere on optical telescopes. Discover how the geography of Mauna Kea, Hawaii helps astronomers overcome the problems of light polllution and the atmosphere. See why you might need a coat to visit the Big Island!

Print out as sets of cards. Students match the appliance to its power rating (appliances and answers in same order). Can they spot that high power usage linked to heat? Use then as basis for energy calcs either in Joules or kWh.

For the triple separate science AQA pathway every required practical for the physics has been included with various skill parts pupils have to complete as they work through the booklet. The additional excel spreadsheet shows which skills are tested for each required practical.
Ideal revision tool at the end or to work through and keep in a folder over the KS4 years to refer back to.
Ready made booklet to hold a stargazing evening at your school.
Lots of activities and information, can be used for the BBC Stargazing evening or just for a STEM event.
The booklet has my old schools name on and logo. Feel free to change these for your own!
