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+.

Fossils make fun and unique gifts for children captivated by the world around them, and are ideal for older children who may be on the verge of growing out of toys. While the price of fossils can vary considerably, with many being worth thousands of pounds, there are some great low-cost options that make ideal gifts for older children with an interest in science. Look out for trilobites, ammonites and fossilised plants for low-priced starter fossils.
You can even buy kits (such as those made by National Geographic) of fossil and geode bundles with information packs for an instant prehistoric collection.
Buy ammonites from about £5 from Mr Wood's Fossils.
