How Can We Get Plop To Sleep?

As part of our class reading book 'The Owl who was Afraid of the Dark',Year 3 have been finding out all about Plop the Owl who, much to his parent's dismay, does not sleep in the day time. As part of our science work on light we carried out investigations to determine which material would be most suitable for curtains to block out the light so that he will finally get some rest.
We made our predictions and then tested each material fairly so that we could determine which material would be most effective.
