The UV index is a forecast (provided by the Met Office in the UK) of UV radiation for each day across different regions. It is expressed as a number from 1-11 as follows:

UV Index

Index     Exposure 

1-2         Low

3-5         Moderate

6-7         High 

8-10       Very High

11          Extreme 

 

a) Ask students to research and make notes on these:

  •  What the UV Index is
  •  Where you can find it
  • Why it is important.

b) Students quiz each person at home (parents/carers/siblings/older family members) to discover if they know what the UV index is:

  1. Do you know what the UV index is?
  2. What does the UV index measure?
  3. Why is it important?

b) Ask students to share what they have found out. Look at the Met Office UV forecast (search ‘UV Index’) and find out how it works.
