Playing and spending time outdoors is good for your students but it is important to protect their skin when outside in the sun. Protect yourself and your students by following and promoting the SunSmart guide to protecting skin and eyes.
The UV index tells us what level of UV radiation is reaching the earth's surface. It ranges from zero to 11+. The higher the UV index, the greater the risk of skin and eye damage and the less time it takes for harm to occur.
In Ireland, the UV index is usually 3 or above from April to September, even when it is cloudy. Stay safe by limiting time in the sun when UV is strongest, typically between the hours of 11am to 3pm.
Getting too much sun can be harmful whatever your age. It exposes your skin to ultra violet radiation (UV rays) that can damage your skin and lead to skin cancer. With good protection against UV rays, most cases of skin cancer could be avoided.
This doesn’t mean you have to avoid the sun completely. Sun exposure is the best natural source of vitamin D and is important for general health. You can still go for walks, enjoy the garden and get involved in all of the things you enjoy doing outdoors. Just make sure to think about how you will protect your skin when outside.

Ultraviolet light is invisible to the human eye but you can still detect it. Science on Stage Ireland has produced a demonstration guide for detecting ultraviolet light using tonic water. The tonic fluoresces bright blue in the presence of ultraviolet light. A component of tonic water (quinine) absorbs the ultraviolet light energy, electrons in its atoms become excited--that is, their energy level increases.

The Royal Society of Chemistry held a global experiment on UV protection called Starlight. The Starlight resource material is still available. The experiments can be run consecutively or individually. They have been designed to challenge all ages and abilities with all resources being easily sourced and affordable. Each experiment can be completed in an hour-long lesson but can also be extended. Teacher Guide | UV Colour Chart

The global experiment is now closed, however, students can access the global results and compare data recorded from different countries. Alternatively, students could pin their results to a classroom board.
