Thames & KosmosKids First Crystals, Rocks & Minerals Science Experiment Kit, Intro to Geology, Mineralogy & Crystal Growing for Early Learners

This was an awesome choice ! My daughter and I do tons of “experiments” because she lives to learn and loves every minute of it. She is huge on rocks and this was a huge hit with her! Easy to use and easy to follow instructions. My girl is three && more patient than most so this was an amazing find for us ! Can’t wait for out next purchase like this !

This Thames and Kosmos Kids First Kit is essentially the same as the Thames & Kosmos Earth Science : Crystals, Rocks and Minerals. We have both kits and my 8 and 10 year old enjoyed doing the earth science activities. I think that parental supervision is needed for this kit. I read through the clear, easy to understand instructions prior to my children starting the labs.For best results with growing the crystals, you will need distilled water. Some of the crystals take at least a week to start growing, so be patient and have the kids check the solution daily. There are 6 crystal growing labs in this kit. All of them worked out for us.There is also experiments involving rock testing, making paper models of crystal shapes and two plaster-based activities. Making the plaster geode filled with alum crystals takes a couple of days but my kids enjoyed doing it. The sand and plaster layered experiment was also enjoyable for them to do. This is a nice earth science kit for children that is fun and educational at the same time.

My kiddo loves anything rocks related. This is a huge hit and she can spend hours exploring. This is our second set. The first set was gifted to us many years ago and now my youngest age 9 is loving it. Makes a great birthday or Christmas gift.

This kit is easy to use with adult supervision, though patience is needed with some of the experiments. 30 mins of stirring to make sure the powders have dissolved will test the best of us.

This is a great kit for a great price. It was the perfect gift for my geology loving third grader! What a great way to spend time together!

Great gift for my 6 year old! She loves it!!

My 8 yo grandson and I had a blast with the kit. He enjoyed trying the mineral testing procedures, but the crystal kit was a lot of fun. We got enormous alum crystals and some very nice Copper Sulfate crystal. The Potassium Cyanoferrate didn't turn out quite as nicely. My only minor complaint is it would have been nice to have more of the Copper Sulfate and Potassium Cyanoferrate to repeat experiments, but, more importantly to be able to create a supersaturated solution as that forms better crystals. That works really well for the alum.
