Can you grow a rainbow?

Good afternoon lovely Nursery class!

I hope that you are all feeling well and enjoying some time to explore your fun, creative ideas. I spotted this scientific challenge earlier in the week and it made me think of you all (because we certainly love a rainbow in our classroom!) so I wondered if you'd like to give it a try... It's called 'Can you grow a rainbow?' and to do this, you will need: 1 piece of kitchen roll, a pair of scissors, some colouring pens and two small glasses/cups of water. If it helps, you could also use a paperclip and some string to hold onto the rainbow during the experiment.

First of all, you need to cut your piece of kitchen roll into the shape of a rainbow - it's easier if you fold it in half first to make it more symmetrical. Then with your colouring pens, you need to colour in the bottom of each side of the rainbow (red, orange, yellow, green, blue, purple and pink if you can). Attach the paperclip and string now to the top of the rainbow (if you have chosen to use them). Finally, place each end of the rainbow into one of the cups of water and see what happens!

Fingers crossed, your science skills of 'following key instructions' and 'observation' will help you to create your very own rainbow! As the kitchen roll absorbs the water, the colours should spread across your rainbow shape to form a bright and beautiful rainbow :)

Best of luck!
