A.1.1.5 Charged coupled device<br />
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%.<br />
A.1.2 Non-optical Telescopes<br />
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.<br />

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:
Nasa video presentation. 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.
This is a worksheet that students can use to consolidate their knowledge and understanding. <br />
The worksheet is differentiated and includes a checklist, key words and an extension task (Legendary Level).<br />
There are several ways in which you can use the task sheet.<br />
1. After an explanation give students time to work at their own pace on the tasks they wish.<br />
2. Select a specific task for students to complete.<br />
3. Use each task as separate parts of your lesson.<br />
4. Set the task as a book or computer based research task.<br />
5. Set the task sheet for homework. <br />
This task sheet covers<br />
1. Describing the ways in which the universe could have been created.<br />
2. Describing the Big Bang theory.<br />
3. Describing and evaluating the Big Bang theory.<br />
4. Describing the big yawn and big crunch.
Outstanding resources for teaching waves and how they can be used to identify the structure of the earth.<br />
Includes, active learning, KAGAN, AFL, hinge points, exam practice, and homeworks to make your planning much easier!
