Eye, Magnifying Glass, Microscope
photographs by Bruce Iverson
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.
Look closer and you can see its head and where its legs attach to its body.
If you could look at it under a microscope, you might not even know you were looking at a spider's head.
You can see a leaf with your eyes.
With a magnifying glass you can look closer at the veins that carry food and water to the plant.
But you need a microscope to see the tiny openings on the leaf that let air in and out.
- A microscope is used to see things that are too small to see with our eyes alone. Microscopes can make tiny things look big.
- What form of matter are a flower, a spider, and a leaf? How you do you know?
[anno: A flower, a spider, and a leaf are all solids. They are solids because they have their own shape.]
- If you looked at a gallon of water from the ocean under a microscope, what might you see?
[anno: Answers will vary but could include that students would see tiny creatures in the liquid that are naked to the human eye.]
- Do you think it is easier to study a solid, a liquid, or a gas under a microscope? Why?
[anno: Answers will vary but could include that a solid might be the easiest form of matter to study under a microscope because it keeps its shape and would not have to be contained in something else in order to study it.]
