While a home microscope is a must for any science-loving child (and there are many great kits available at various price points) you do risk spending money on something that might lose their interest. With a portable microscope, such as the Brainstorm Outdoor Adventure Microscope, you get an extremely well-priced starter microscope that children can wear around their necks and take out on walks, nature trails or even in the garden to examine flowers, minibeasts and anything else that takes their fancy.
Recommended for ages 6+.
