There are many ways to look at things around us. You can look at flowers with your eyes and see beautiful colors and patterns.
A magnifying glass makes the flower look bigger. You see details that your eye missed.
And with a very powerful microscope you can see these spiky balls. They are the grains of powdery pollen that bees collect when they make honey—and that can make you sneeze!
You might see this orb weaver spider spinning its web in your garden.
