Meet Nebula. She loves painting and learning about microorganisms. Nebula's parents are scientists and they gave her a microscope kit to learn more about the tiny organisms in her world. Sometimes she paints the cool things she sees and shares them with her friends. Can you name a microorganism she should paint?
