Welcome to this lesson on Animal Superpowers: Bees Can See in Ultraviolet. Bees can see in ultraviolet which humans cannot see. So, why might this be? First, I'll talk about what ultraviolet is. Colors are actually wavelengths that our eyes interpret as colors. Each color has a different size wavelength which our brain sees as different colors. But humans cannot see ultraviolet. Ultraviolet wavelengths are shorter than violet, and our eyes cannot detect the size. X-rays are even shorter, and we definitely can't see those. These really short waves are ultraviolet waves. So, why do bees see in ultraviolet? It turns out, flowers that attract bees have ultraviolet colors that signal to the bee where the pollen is. To humans, this looks like a normal flower. But when using an ultraviolet camera, it looks more like this with a darker circle leading to where the pollen is. It turns out that flowers that attract bees have ultraviolet colors that signal to the bee where the pollen is. This is why bees have the extraordinary sense that they can see in ultraviolet vision.
Kids earn more screen time by answering fun educational questions.
Here are some example of questions about this video that kids may be asked in the 1Question app to earn screen time.
