What magnification does the microscope need to have for high school?

Sonlight's Ultra Microscope includes 40X, 100X, and 400X to give your student's opportunity to see tiny details. To ensure your students have the best lab experience, we recommend using a microscope with up 400X, though the range provided in Sonlight's Ultra Microscope makes it easier for students to locate what they want to view before zooming all the way in.
