My 5-year-old and I made a shoebox aquarium (see photo) during the holidays. She has been learning about the natural environment at school and decided to get creative. She made fish and an octopus and a shark, and decorated them all with googly eyes, smiley faces and glitter sparkles. She drew eyelashes on the fish, which made them look super-cute, but it got my 9-year-old thinking:
Do fish actually have eyelashes? What about eyelids? And do they need to blink or does living in water mean that they can always keep their eyes open?
