Our UV BEADS Experiment!

On Wednesday Mr Yardley gave each class a packet of special beads.  We put them onto some string and put them on our wrists before going out to lunch.  Mrs Brown said to keep an eye on them over lunch and see what we noticed!

After lunch we talked about what had happened to our beads during the lunch break.  We all found that our bead changed colours during lunchtime!  Wow - were they magic? 

Here are some of the reasons/observations as to why we thought they changed....

·      They are made for glowing outside – Sven

·      They change to blue when you were eating lunch – Eve

·      I was standing on the step and it turned purple – Tarin

·      By Room 14 mine changed colour – Ameelea and Ashley

·      Outside it was glowing but inside it wasn’t – Coco

·      I noticed when I went in the sun it changed colours – so I think it's something to do with the sun and the dark – Riley

Mrs Brown talked to us about how they were UV Beads which change colour when they have exposure to the sun.  UV rays or ultra violet rays, are present all the time - even on a day like Wednesday when the sun was not shining in the sky!  It made us realise that even though the sun is not bright and it is a cloudy day - it is still very important to have protection from the sun by wearing a hat and sunblock.

We are going to wear them over the next few days in lots of different places and see what we observe!  

Can you see our beads have changed colours now that we are outside?
