Lesson Title: Today we are learning about
What factors affect radaition and emission?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Students should be able to explain that all bodies (objects) emit radiation. (HT only) A body at constant temperature is absorbing radiation at the same rate as it is emitting radiation. All bodies (objects), no matter what temperature, emit and absorb infrared radiation. The hotter the body, the more infrared radiation it radiates in a given time. Since a good absorber is also a good emitter, a perfect black body would be the best possible emitter. Students should be able to explain that the intensity and wavelength distribution of any emission depends on the temperature of the body. A perfect black body is an object that absorbs all of the radiation incident on it. A black body does not reflect or transmit any radiation. (HT only) The temperature of a body increases when the body absorbs radiation faster than it emits radiation. (HT only) The temperature of the Earth depends on many factors including: the rates of absorption and emission of radiation, reflection of radiation into space. (HT only) Students should be able to explain how the temperature of a body is related to the balance between incoming radiation absorbed and radiation emitted, using everyday examples to illustrate this balance, and the example of the factors which determine the temperature of the Earth. (HT only) Students should be able to use information, or draw/ interpret diagrams to show how radiation affects the temperature of the Earth's surface and atmosphere.

Keywords:

Reflect: when waves bounce back off a shiny surface (1)
Emitter: a substance that will transfer energy to its surroundings (1)
Radiate: transfer of energy to the surroundings (1)
Absorb: take in or soak up energy or a liquid or other substance. (1)
Use this as the enquiry question ahead of the homemade Leslie cube demo (1)

AFL/Key Questions:

(Physics only) Do only perfect black bodies (objects) emit radiation?
All bodies (objects) emit radiation.
(HT only) (Physics only) What is happening in terms of radiation and emission when a body is at a constant temperature?
(HT only)A body at constant temperature is absorbing radiation at the same rate as it is emitting radiation.
(Physics only) At what temperature do all bodies (objects) emit and absorb infrared radiation?
All bodies (objects), no matter what temperature, emit and absorb infrared radiation.
(Physics only) What is the relationship between temperature and radiation of infrared radiation?
The hotter the body, the more infrared radiation it radiates in a given time
(Physics only) What colour object would be the best absorbed and emitter of radiation?
Since a good absorber is also a good emitter, a perfect black body (object) would be the best possible emitter.
(Physics only) What factors affect the intensity and wavelength distribution of emissions from a body (object)?
The intensity and wavelength distribution of any emission depends on the temperature of the body.
(Physics only) What is a perfect black body (object)?
A perfect black body is an object that absorbs all of the radiation incident on it. A black body does not reflect or transmit any radiation.
(HT only) (Physics only) What happens when the temperature of a body (object) increases?
(HT only)The temperature of a body increases when the body absorbs radiation faster than it emits radiation.
(HT only) (Physics only) What factors can affect the temperature of the Earth?
(HT only) The temperature of the Earth depends on many factors including: the rates of absorption and emission of radiation, reflection of radiation into space.
(HT only) (Physics only) Give an example of when the balance between incoming radiation absorbed and radiation emitted results in a constant temperature of a body (object)
(HT only) The constant temperature of the Earth.
(HT only) (Physics only) What affect to the temperature of the Earth's atmosphere would an increase in radiation absorbed have?
(HT only) If the amount of radiation absorbed by the Earth's atmosphere was to increase, the overall temperature of the Earth would also increase.

Starter Activity	Differentiation and Challenge question/task
Students to copy and complete the keywords. Teacher reveals missing letters; Students correct mistakes; Discuss the scientific meanings of the words. Students to write down the definitions of the most important / new keywords. Discuss the 'Memory Anchor'. What does it show? How does it relate to the what we are learning about today (title)?
