This is one of the better introductory microscopes out there. This one is more of a student microscope than a toy, and its fairly low price makes it one of my favorite children’s microscopes available anywhere. There are two basic types of lab microscopes - compound scopes with bottom illumination and high magnification, and dissecting scopes with only top lighting, lower magnification, but a true three-dimensional view. The My First Lab Duo-Scope microscope combines the two types of microscopes into one and is therefore excellent for classroom or homeschool use.
An actual laboratory instrument made by C&A Scientific, the metal scope features dual lighting so you can view up through a slide at powers up to 400x or down into a solid object at low 40x magnification. Like other First Labs products, the Duo-scope has a professional slant design and real precision-ground optical lenses, which means easy focusing and clear viewing, even for a novice.
This microscope also comes with a simple but nice kit for making your own slides. You will need three AA batteries for the light. This one also made the list of Best Selling Christmas Toys of 2008 from Atomic Elephant Science and Toy Company.
The Dozie 6 tennis ball is the perfect toy for him. Science Toy
