Know your suncream

Learn about SPF and the different types girls need to stay in the sun.


  1. Inside or under some shade, line up the suncream bottles and cut a piece of photo-sensitive paper into four A6-sized pieces. Place each one inside a zip-lock bag and seal it. Pin each bag to a stiff piece of cardboard and write on it which SPF will be used. The fourth will be a control.
  2. Smear the correct suncream onto the outside of each bag. Leave the control without any suncream.
  3. Set the paper out in the sun. Wait for five minutes.
  4. Bring the paper inside and submerge it in the tub of water to stop the process and fix the images.
  5. The more blue the paper, the more UV rays came through. The whiter the paper, the more UV rays were blocked by the suncream.
