With an emphasis on how important light is to our planet, this beautifully-illustrated book explains how light affects photosynthesis, how light travels, and light’s different properties. Whether it’s ultraviolet light that helps bees pollinate flowers or solar panels that use sunlight to heat our homes, students learn about the various ways that both animals and people depend on light.
