MBE STEM Science Kits Review and Giveaway (age 8+) Sent by Thames And Kosmos

I like science toys best of all and I'm delighted that my boys love them too. Thames and Kosmos have a huge range of science, mind and exploration toys, games and puzzles. Their brand new MBE range of science kits includes 8 different sets designed to allow your child to explore their world and learn something new and exciting, and at only £8.99 each, they make a great birthday gift for friends.

The new kits are designed to introduce different scientific topics, with fun facts and interesting hands-on experiments, and Thames and Kosmos have sent us 2 to review - Amazing Minerals and Crystal Geode.

The Amazing Minerals Experiment Kit is a nicely presented digging kit with 2 tools, magnifying glass and the familiar chunk of plaster containing the hidden treasure.

The instructions suggest you behave like a real geologist or archaeologist, marking your area into squares and working in sections. My son really liked this idea and it was around 30 minutes before he had proudly excavated all three of his precious stones.

Each kit contains a purple Amethyst, a milky white piece of Mountain Crystal Quartz and a stony, glittery piece of Pyrite, or Fool's Gold. Before you uncover them though, you really have no idea what shape or size they'll be, or just how pretty.

I think we did very well and my 9 year old is very happy - especially with his Fool's Gold!

Our second kit is a bit more complicated, but only slightly. The Crystal Geode Experiment Kit has everything you need to actually create your own geode, and I love geodes, so I was particularly excited about this.

First you need to dissolve one of the sachets of chemical 'Crystal Powder' (Potassium Aluminium Sulphate) into warm water to create a 'seed crystal', and leave it to sit until the 'seeds' are ready to be taken out. I had expected the 'seeds' to be more chunky, but here they are, small and beautiful.

Use the plaster of Paris to create your geode 'rock' and scatter the seed crystals onto the damp plaster. Let that dry for 24 hours.

When the 'rock' is dry, mix up the second sachet of Crystal Powder and add in the colour dye sachet. Pour the dyed chemical mix into the rock, sit back and wait for your crystals to grow. Once you are happy with your formation, you can remove the plastic mould and tip away the excess liquid and crumbs of tiny loose crystals that are created.

It takes a few days and it's entirely my fault that we haven't yet been able to complete this... I promise I will post our progress on my Instagram account!

I love these kits. They're carefully thought out, interesting and the instruction leaflets are very clear and easy to follow. My children needed a little help with the Crystal Geode kit because you have to heat your mixture, but it's well worth 5 minutes adult supervision to be able to do a more tricky and 'grown up' scientific experiment, and my children learned a lot about how to be safe and sensible while heating and moving chemicals.

Amazing Minerals – excavate minerals like a real geologist!

We were sent our kits for review. *Amazon links are affiliate, which never costs you anything more, but earns me a few pence if you buy through my link. I'm not paid to cover children's STEM, so it helps keep the website free. 


  1. During a recent holiday on the Isle of Arran, I saw a kingfisher hovering over a stream! It has to be the prettiest of birds I have ever seen - it's feathers were so vibrant!

  2. A bottle filled with all newspapers - dates from 30 years previously ! So many great finds on beaches

  3. I would also be Fossils that I found.

  4. It was a sunset one evening. The weather that day wasn’t particularly spectacular, but I walked down the road to be greeted by those clouds. Beautiful pinks fading into bright yellow. It was certainly the most sublime combination of colours I have ever witnessed. I’ve never seen a sunset that compared since.

  5. I saw a pineapple plant in St Lucia, up until then I had thought pineapples grew on trees

    It was a few,months was a tree that looked just like a human. My little girl was fascinated xx

  13. I think it has to be fossils for me too - fossilised fish, in a quarry in Caithness. It's so exciting to split open a piece of slate and see the remains, knowing you are the first person to see it for many thousands of years

  14. Margaret Clarkson

  15. A ghost of an old lady picking flowers in the garden.
