GeoSafari Jr. My First Microscope allows kids to see magnified hidden worlds with ease! This fully functional microscope is a real tool with a range of magnification (2.5x–8x) designed with a preschooler in mind. Magnified views can be challenging for little ones to understand, so by starting with the 2.5x view (with the focusing knob turned as far away from your child as it will go), your preschooler can orient herself to the item she’s viewing, and as she turns the focusing knob towards herself, she can gradually pull away to an 8x view.
