Irvington Seventh-Graders Learn to Use Microscopes, Make Observations

IRVINGTON, NY - Seventh-graders in Nicole Arvanites’ Irvington Middle School science class recently learned how to use the microscope and make proper scientific observations with it.

As part of their lesson, the students demonstrated how to use and focus a microscope from a lower to a higher power objective lens. They also had to determine what happens to the image of a specimen when it is observed under the microscope.

“The students were surprised to see everything was flipped and upside down,” Arvanites said. “They will use this understanding to help them when observing microorganisms in our protists unit.”

A protist is a one-celled organism.
