UEFA launched a campaign called Cleaner Air, Better Game. Footballers need the air to be clean to perform well, just like all of us.
Here's a fun way of seeing what the air is like around where you live.
What do you need?
- Petroleum jelly
- 4 pieces of white cardboard circles (approx 15 cm diameter) or 4 white paper plates
Step by step
Collect all the things you'll need we've listed. Punch a hole in the upper part of each piece of cardboard (or plate) and pass a string through it. You'll use the string to hang the plate up.
Draw a circle on each piece of cardboard (or plate). Try and make each circle about the same size. Then smear a thin layer of petroleum jelly in the circle. To be able to compare results properly, try and have same amount of jelly spread in each circle.
Hang up the cardboard plates in different places: at home, in your classroom or outside (make sure it is sheltered from rain). Wait 5 to 7 days to have a look at it. Compare the different plates! To really examine what is in the air, look at it with a magnifying glass.
To score your goals, make sure to upload a picture of your results!
Most likely you can find it in a chemist's shop.
You can also use vaseline.
