Read page 17 of the biology text book "Magnification of images"
Collect a secure, develop or challenge sheet to have a go at using this equation to either calculate magnification or the size of the real object.

How do you know what magnification you have your microscope?

# data[].attributes.body
The size of objects can be measured in meters (m), centimeters (cm), or millimeters (mm). However cells are so small they are measured in micrometers (µm). Research these answers
1. How many cm in a m
2. How many mm in a cm
3. How many µm in a mm
4. How do you convert something from mm into µm?
5. How do you convert something from µm into mm?
