Round up of National Geographic Stem toys from Bandai (and Giveaway)

(AD) As ambassadors in the 2021 Bandai National Geographic STEM blogger club we have tried lots of the National Geographic STEM range. From dig kits to crystals and slime we’ve prodded, polished, brushed, mixed, grown, explored and learned so if you are looking for a great STEM activity for children aged 8 and upwards which of the National Geographic kits might be best for your child?

Our Recommendations for the Best STEM Kits in the Bandai National Geographic Range

Best Kit for Impatient Children

If your child wants to jump right in and explore then the Sensory Science kit is really good because as soon as you open the box it is ready to play with the (very cool) hydrophobic sand, play sand, slime and putty. No prep needed.

Best for Fans of Dig Kits

The Ultimate Gemstone Dig Kit was our favourite of all the dig kits we reviewed because there are so many gemstones to find in the dig block. It’s also great that there are lots of less common stones in there so children will love building up a collection.

Best for Dinosaur Fans

The Dino Fossil Dig Kit has a nice balance of 3 items to find in the dig block and will hold interest longer than the mini kit.

Best for Slime Fans

Both the Glow In The Dark Science Kit and Sensory Science Kit contain slime with the big difference being you mix it yourself with the Glow In The Dark Science Kit and it is ready made in the Sensory Kit, with the different textures to explore slime loves might like the Sensory Science Kit best though.

Best Pocket Money Item

The mini dig kits are the lowest priced of the National Geographic STEM kits. Each kit only has one item to find so they aren’t the most exciting, but they are a price children can afford with their pocket money and good if they want to build up a collection. Because they contain genuine items each find will be different making it interesting if they want to build up a collection. The standard sized dig kits are about twice the price, but you get 3 items so they are are a good option too.

Best All Rounder Kit

The Earth Science Kit is great because you get a good range of activities: there are stones to investigate straight away, pyrite to dig out a block, crystals to grow, a volcano to make (and erupt) and a tornado.

It’s a great starter kit and you can then (depending on which they like best) get more eg if they enjoy the concept of the dig kits you can get more of these.
