This week we have enjoyed being scientists along with the children from rooms 1 and 2 as we have undertaken a few simple experiments and made some discoveries about rainbows.
We started by wandering outside with prisms and were excited to find rainbows on the ground. When we came inside we discussed what we’d seen and read about prisms in a book. We learnt that the bending of light through a prism is called refraction.
Next we did an experiment with a torch, mirror and water and by shining the torch on the mirror we could make a rather faint rainbow on the cardboard.
We have learnt that when you see a rainbow in the sky, it is caused by the sun shining through water droplets in the air. The water droplets are acting like tiny prisms. They cause the light to refract. The light spreads apart into the spectrum, the colours of the rainbow.
Later in the week we went outside and blew bubbles in the sun and kept a keen eye on them to see if we could see rainbows within them. It was so much fun we laughed a lot and chased the bubbles around our playground.

During one of our discussions about rainbows I told the children that when the sun shone through my bathroom window in the morning a rainbow appeared on the bathroom wall and that it was circular in shape. Cate from our class suggested I take a photo of it so I did! The children were fascinated.
