Teacher Notes:
The study of lenses and light is called
optics. Students will discover
how images can be controlled by lenses to help observe small things. A
microscope uses the physics of optics to allow us to see small things our
eyes cannot detect. This activity has students discover how images are
formed. You should go over the parts of the microscope together.
This depends on the microscopes that you have available.
Set up the lab so
students learn to focus an object under the microscope.
The first exercise has them focus
on a piece of paper. They
should observe that the object is upside down and much smaller.
The best way to do exercise is to have the students face a window
and create an image on the paper.
Students should learn
that there is a set distance to focus an object whether it is the
reflecting microscope or transmitting light microscope.
