Learning outcomes and Specification referenceEdit

P1.1.1 Infrared radiation P1 Lesson 8&9 Emission of Infra Red radiation
a All objects emit infrared radiation. Understand what infrared radiation is.
b The hotter an object is the more infrared radiation it radiates in a given time.

Understand what infrared radiation is.

c Dark, matt surfaces are good emitters of infrared radiation. know the factors which affect the rate at which an object radiates infrared radiation
d Light, shiny surfaces are poor emitters of infrared radiation.

Practical activitiesEdit

DemonstrationsEdit

  • Ignite bubbles full of methane using a splint on a metre ruler (Read Cleapps model risk assessment). Students will feel the heat on their face. You can have them stand side on and they will experience a marked difference in the heating affect on the two sides of their face
  • Get students to veiw a remote control using the camera on their phones. As the buttons are pressed the IR LED will appear to light up when viewed in the camera phone. This is because the camera sensor responds to IR light. This does not work well with phones that have better cameras. It appears not to work on some models of ipod
