Full Specification Text[]
a) All objects emit and absorb infrared radiation.
b) The hotter an object is the more infrared radiation it radiates in a given time.
c) Dark, matt surfaces are good absorbers and good emitters of infrared radiation.
d) Light, shiny surfaces are poor absorbers and poor emitters of infrared radiation.
Starter Activities[]

Activities to introduce new ideas[]
- A Nasa video (6 mins long) about infra red. Lots of everyday objects viewed with IR camera. Also links to Infrared astronomy. A great video from Nasa (6 mins long) about infra red. Lots of everyday objects viewed with IR camera. Also links to Infrared astronomy.

Practical activities[]
Demonstrations[]
- 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
